Thank you, Ann, good morning, everyone. This morning, we reported strong second quarter results, raised our full year 2018 outlook. All businesses met or exceeded expectations for the quarter, with year-over-year sales growth in each. Highlights include Optical sales were up 16% year-over-year, we are increasing our expectations for full-year organic sales growth. Environmental sales were up 21% year-over-year, we have also increased our full-year outlook. Specialty Materials performed better than expected. We anticipate year-over-year sales growth in quarter three and for the full year, driven by strong shipments of innovative new products. Finally, progress towards stable returns in Display continued, with sales and net income in line with expectations. The pricing environment in Display is the best it has been in more than a decade. We expect to reach the important milestone of annual price declines improving to a mid-single-digit percentage in quarter three.
In total for the quarter, sales were $2.8 billion, up 9% year-over-year. Net income was $359 million, and EPS was $0.38. We completed a strong second quarter in terms of financial performance and progress on our investments. As planned, we undertook a phase of intense operating and capital investments to help us meet committed demand and capture new opportunities. We have now reached an inflection point where those investments are yielding clear benefits, including increased sales and greater profitability. Several of our largest projects have exited the startup phase, and production and efficiency rates are climbing. We are on track to meet increased demand, grow sales, and significantly improve profitability in quarter three and beyond. Specifically, we expect to expand margins and reach approximately $11.3 billion in full-year 2018 sales, up 10% year-over-year, and an increase from our prior expectation of $11 billion.
We feel great about both the back half of 2018 and our long-term opportunities, as Tony will describe in a little more detail in just a few moments. Let's turn to the strategy and capital allocation framework, which outlines our leadership priorities. Under the framework, we target generating $26 billion-$30 billion in cash through 2019. We plan to return more than $12.5 billion to shareholders through repurchases and dividends and to invest $10 billion to extend our leadership and deliver growth. We have made great progress toward those goals since we announced the framework in October of 2015. Our cash generation is on target, and through the end of the second quarter, we have returned $10.8 billion to shareholders. Dividends per share have increased 50% since the framework began.
Investments in RD&E Capital expenditures and acquisitions also remain on track to our four-year plan, totaling $6.7 billion through June 30th. As outlined in our framework, Corning is the best in the world in three core technologies, four manufacturing and engineering platforms, and five market access platforms. Our capabilities are interrelated and reinforcing. We focus 80% of our resources on opportunities that use capabilities in at least two of these three categories. This increases our probability of success, reduces the cost of innovation, creates stronger competitive barriers, and most importantly, delights our customers. I'll turn to our progress in each of our market access platforms, starting with Optical Communications. We remain the world leader in passive optical solutions and the only true end-to-end supplier of integrated solutions. Our outstanding performance in Optical Communications continued in the second quarter and helped drive an increase in our full-year outlook.
We expect full-year sales to be up by a high teens % year-over-year, with organic growth increasing to the low teens versus our prior guidance of 10%, plus an additional $200 million in sales from the acquisition of 3M's Communication Markets Division. Strong market demand and the continuing success of our co-innovation model have resulted in faster than expected progress toward our goal of $5 billion in annual sales by 2020, with continued growth thereafter. We reached a major milestone in June when we completed the acquisition of 3M's Communication Markets Division. This investment extends our market reach and access to global customers while expanding our portfolio in the rapidly growing optical solutions markets. We continue to introduce award-winning products. Our EDGE Mesh Modules received the Data Center Cabling & Connectivity Product of the Year Award in the second quarter.
This family of products has emerged as a critical enabler of data center networks. The award demonstrates strong support from our customers, distributors, and peers. Stepping back, we've positioned our Optical Communications market access platform to deliver advantaged optical fiber, cable, and connectivity solutions for access networks, cloud data centers, and the network densification necessary for 5G and even autonomous vehicles. We're excited about our excellent performance, our current growth, and our future opportunities. Let's turn to mobile consumer electronics, where we are the world leader in glass for smartphones, tablets, and emerging categories like wearables and augmented reality devices. Our goal is to double mobile consumer electronics sales over the next several years. We continue to make significant progress in adding more sales dollars per device by innovating in both glass and value-added components, while also expanding our share in developing regions and entering entirely new product categories.
Gorilla Glass has been designed into more than 6 billion devices worldwide. Last week's launch of Corning Gorilla Glass 6, the world's most durable cover glass to date, extends our market leadership. Research indicates that consumers drop their device on average seven times a year. It's no surprise that having their devices survive multiple drops is important to our customers, and the innovations contained in Gorilla Glass 6 provide a significant step forward. In lab tests, our new glass survived on average 15 drops from one meter onto rough surfaces. That's about twice as many drops as Gorilla Glass 5. Competitive glass compositions under similar conditions did not survive even the first drop. One of our levers to double sales is to increase revenue per device, and we fully expect Gorilla Glass 6 to make significant contributions toward that goal.
Customers have shown very strong interest, you should be hearing announcements from them in the near future. Increasing penetration of glass backs to enable wireless charging and higher data rates also supports our goal of doubling sales in mobile consumer electronics. The fundamental properties of Gorilla Glass make it an ideal choice for both the fronts and the backs of smartphones. In 2018, we expect 28% of smartphones sold to have glass backs, nearly double the amount sold with glass backs in 2017. We're also innovating in new device categories. Gorilla Glass continues to be the most widely used cover material on smartwatches. Last week, we launched Corning Gorilla Glass DX and DX+, which offer enhanced anti-reflective optics and extreme scratch resistance for wearables. We're also sampling these new composite materials in the handheld space.
Our broad product portfolio has enabled continued wins in developing regions and value segments. In the second quarter, General Mobile announced the GM 8 smartphone in Turkey, and Positivo launched the Ska smartphone in Brazil, both featuring Gorilla Glass. We also remain well-positioned with innovative glass-based solutions for emerging applications, including augmented reality and precision 3D sensing. Overall, we expect sales in Specialty Materials to grow in 2018 as more devices adopt Gorilla Glass 6 and our other innovations. Turning to our automotive market access platform. Our expertise focuses on helping customers build cleaner, safer, and more connected vehicles. Corning reached a significant production milestone of 1 million gasoline particulate filters as we lead the market in the next wave of emissions control. We're partnering with most automakers to equip their new European gasoline engine platforms with our technology.
China will be the next market to introduce GPF, and we're preparing by increasing the pace of investment in our new Hefei China facility. Once regulations are fully implemented in Europe and China, we expect gasoline particulate filters to add a half a billion dollars in annual sales for Corning. Excitement about Gorilla Glass for Auto continues to grow as the industry transitions to highly connected and autonomous vehicles that use technical glass. Calls for collaboration from more than 20 leading OEMs is increasing, and customer commitments now support the creation of dedicated finishing capacity for Gorilla Glass for Auto interiors. Earlier this month, we announced an investment in a Hefei facility that will produce Gorilla Glass parts for automotive interiors. We expect it to be operational in 2019.
In our life science vessels platform, we continue to make strong progress on the path to a new long-term multibillion-dollar franchise. Valor Glass dramatically reduces particle contamination, breaks, and cracks while significantly increasing throughput. Valor helps protect patients and improve pharmaceutical manufacturing. Our collaborators, Merck and Pfizer, continue to demonstrate support for Valor. In April, both joined us for the announcement of a high-volume manufacturing facility in North Carolina, which was an important part of the plan we announced last July. Both companies also spoke about the merits of our technology and collaboration at separate industry conferences. In mid-June, Merck presented its perspective and findings on an important patient safety attribute of Valor. Later in the month, I joined a senior Pfizer leader to share some perspective on Valor, our collaboration, and Corning's long track record of co-innovation. At the event, Pfizer leadership affirmed its commitment to Valor.
The leader said, quote, "We're working as fast as we reasonably can to provide those solutions we're talking about today," end quote. Earlier this month, the Food and Drug Administration reaffirmed its commitment to support new technologies that can improve pharmaceutical manufacturing and help prevent drug shortages. We remain closely engaged with the FDA and support its efforts to address this important public health issue. We continue to believe Valor has the potential to power Corning's growth for the next decade and beyond. In display, we remain the global leader. Our priority is to deliver stable returns and win in new display categories. Progress is excellent this year. Television retail demand growth is strong and higher than we have seen in the past several years. We also have the most favorable pricing environment for LCD glass in more than a decade.
We expect to reach the important milestone of annual price declines improving to a mid-single-digit percentage in the third quarter, and we expect the improvement trend to continue into 2019. As we've discussed previously, we took advantage of seasonally lower demand to upgrade our fleet with the latest technology. We're now completing those upgrades, and our Gen 10.5 plant is ramping on schedule and in tandem with BOE's panel production. As a result of these actions, we expect display profitability to increase substantially in the second half of 2018. We continue to make excellent progress across all our market access platforms. We are investing to capture opportunities and are well-positioned to deliver another strong year of growth. Ultimately, we remain on track to fully achieve our strategy and capital allocation framework goals. Now let me turn the call over to Tony for a review of our results and outlook.
Thank you, Wendell, and good morning. Our second quarter results set the foundation for a stronger-than-expected 2018. Each of our businesses grew sales year-over-year. After investing to support near and long-term growth and to extend our market leadership, we are well-positioned and expect to reach approximately $11.3 billion in full-year sales, up from our earlier guidance of $11 billion. We expect to see sales and profitability improve significantly in Q3, and we plan to build on that going forward. Before I get into the details of our performance and results, I want to note that the primary difference between our GAAP and core results is again a non-cash, mark-to-market adjustment for our currency hedge contracts.
As we've discussed before, GAAP accounting requires earnings translation hedge contracts settling in future periods to be mark-to-market and recorded at current value at the end of each quarter, even though those contracts will not be settled in the current quarter. For us, this resulted in an after-tax GAAP gain of $387 million for the second quarter. To be clear, this mark-to-market accounting has no impact on our cash flow. Our currency hedges protect us economically from foreign exchange rates fluctuations and provides higher certainty for our earnings and cash flow, our ability to invest for growth, and our future shareholder distributions. Our non-GAAP, or core results, provide additional transparency into operations by using a constant currency rate aligned with the economics of our underlying transactions. We're very pleased with our hedging program and the economic certainty it provides.
We've received $1.6 billion in cash under our hedge contracts since their inception slightly over five years ago. That brings me to our results and outlook. Our second quarter core sales were up 9% year-over-year, and EPS was $0.38. The intensive operating and capital investments that we have discussed with you over the last several quarters are now yielding clear benefits. Our investments include the continuation of capacity expansions for optical fiber and cable, our Gen 10.5 Hefei display glass plant, capacity for gasoline particulate filters, Gorilla Glass projects for mobile devices and upper automotive, plus several other development projects. These planned investments constrained our gross and operating margin percentages in recent quarters. With several of the largest projects having crossed major thresholds, we are now at an inflection point. Our sales run rate is climbing, and our gross margin is expanding.
We expect to achieve approximately $11.3 billion in sales for the year and to expand gross margin to 42% in the second half. Turning to the balance sheet, we ended the quarter with $2 billion of cash. Adjusted operating cash flow for the quarter was $833 million. Now let's look at the detailed segment results and outlook. Let's start with Display Technologies, where we're making great progress towards maintaining stable returns. Our results were in line with expectations. Retail sales are very strong globally, and production at our new Gen 10.5 plant is ramping. The pricing environment is the best it has been in more than a decade. Second quarter sales were $780 million, up sequentially and year-over-year. Net income was $192 million. Second quarter sequential price declines were better than Q1, as expected. For the third quarter, we expect sequential price declines to again be very moderate.
These continuing improvements in sequential price declines will allow us to reach the important milestone of annual price declines improving to a mid-single-digit % in the third quarter, and for that improvement trend to continue into 2019. Three factors drive our view that this more favorable pricing environment will continue. First, we expect glass supply to continue to be balanced or even tight. Our new Gen 10.5 plant supports the expected growth of large-sized TVs. It is co-located with and dedicated to our customer, BOE. We pace and align capacity in tandem with BOE to ensure our Gen 10.5 glass supply is balanced to demand. The ramp is on schedule. We expect the glass supply demand balance below Gen 10.5 to tighten further because demand continues to grow in 2018, but public information indicates there is little capacity growth planned in this segment by glass makers.
Second, our competitors continue to face profitability challenges at current pricing levels. Therefore, we expect their price declines will slow further as they try to remain profitable. Third, LCD glass manufacturing requires ongoing investments in current and new capacity to support growth. To generate acceptable returns on investment, glass pricing will need to improve even further. For Corning, we will only add capacity if we can get an attractive return for our shareholders. Moving to retail, TV demand was very strong in Q2. Viewing area grew double digits year-over-year worldwide. Strong demand was driven by lower panel prices, which are having a positive impact on TV retail prices and thus consumer demand. We expect TV retail demand to remain robust for the rest of the year.
As for the LCD glass market, second quarter total market volume grew low single digits sequentially, and our volume grew faster as we ramped production in Hefei, in line with our April guidance. In the third quarter of 2018, we expect the LCD glass market volume to grow mid-single digits sequentially and our volume to grow faster as we continue ramping production in Hefei in tandem with BOE's Gen 10.5 demand. For the full year, we continue to expect LCD glass market volume to grow mid-single digits as television screen size growth continues. We expect our volume for the full year to grow faster than the market, driven by Hefei Gen 10.5 ramp-up. In brief, we feel very good about price and volume. As we described last quarter, first half display gross margin was affected by two factors, the Hefei startup and fleet optimization.
That our factory utilization is increasing, our productivity and gross margins in the second half of the year should improve. In summary, we remain very pleased with the current dynamics in our display business and our progress in maintaining stable returns. Let's move to Optical Communications. Second quarter sales were up 16% year-over-year and exceeded $1 billion. Sales growth was driven by both our data centers and carrier customers. Net income was $150 million, up 17% year-over-year. As expected, capacity utilization and profitability increased due to volume growth and progress on our capital expansion initiatives. We're continuing to bring additional capacity online in the second half to support committed demand. In Q2, we successfully closed the acquisition of 3M's Communication Markets Division. In 2018, this transaction will add about $200 million in sales and be neutral to EPS due to integration costs.
As previously announced, we expect it will be accretive in 2019 and beyond. We expect third quarter sales to be up about 25% year-over-year, including sales from the recently acquired business from 3M. Given the strong first half and our second half outlook, we now expect full year sales to be up by a high teens percentage year-over-year, with organic growth improving to the low teens and an additional $200 million in sales from the 3M acquisition. Overall, we are growing Optical Communications faster than the market. These additional sales are driven by preference for our advantage solutions in the data center and carrier markets and enabled by increased fiber and cable output from our new capacity expansions. We're excited about the growth we're delivering. Environmental Technologies second quarter sales were $317 million, up 21%. All products contributed to our growth.
Second quarter net income was up 42%, driven by volume growth in all product categories, as well as strong performance in our manufacturing operations. As anticipated, the North America heavy-duty market continues the improvement that began in the second half of last year, driving 21% year-over-year sales growth in our diesel business for Q2. In auto, we are also growing our sales faster than the market. Sales were up 21% due to more awarded platforms and a shift to premium products. Additionally, gasoline particulate filters contributed to the growth as OEMs ramp for full adoption of Euro 6 regulations in September. We are making progress with capacity and engineering investments to support the ramp of the GPF business. We expect the strong performance to continue in the third quarter, with sales growth of high teens year-over-year.
We are also increasing our full-year sales outlook to mid-teens growth year-over-year. We expect continued strength in sales of all products, including ramping GPF sales. In Specialty Materials, second quarter sales were $343 million, and net income was $64 million. Sales were ahead of expectations and up 2% year-over-year, driven by higher Gorilla Glass shipments as OEMs begin to ramp for second half product releases. While underlying operations remained solid, net income for the quarter was impacted by product development costs. Although the overall smartphone market is maturing, we continue to progress towards our long-term goal to extend our leadership in mobile consumer electronics and double sales. Our ability to innovate and deliver value-added products at a premium price is playing out as we expected. We delivered another breakthrough innovation with last week's launch of Gorilla Glass 6.
We also introduced Gorilla Glass DX and DX+ to capture more value in wearables. Innovations like these increase the value of our glass, extend our differentiation, and support using more glass in more places. We expect strong shipments of innovative new products in the second half. For Q3, we expect sales to be up about 10% year-over-year. We expect the additional sales to generate strong specialty materials earnings growth throughout the second half. In Life Sciences, second quarter sales were $245 million, up 11% year-over-year, and net income was $31 million, up 41%, driven by strong demand in manufacturing performance. We continue to outpace market growth. Third quarter sales are expected to grow by a mid-single digit percentage over last year. We are also increasing our full year's sales outlook to be up by a mid to high single digit percentage over last year.
For 2018, all of our businesses have positive momentum. We now expect full-year sales of about $11.3 billion, which is up 10%. I'll share some additional outlook details. First, let's turn to gross margin. We expect our gross margin to expand to 42% in the third and fourth quarters, up significantly from the first half and versus last year. Annual operating expenses should remain consistent with last year as a percentage of sales. For the full year, SG&A is expected to be about 14% of sales, and RD&E about 8%. We expect other income, other expense in Q3 to remain at our second quarter run rate of about $55 million-$65 million. For the full year, we expect a net expense of approximately $210 million-$220 million.
Full year 2018 gross equity earnings are expected to be similar to 2017 at just over $200 million, predominantly from Hemlock Semiconductor, with the third quarter at approximately $20 million-$30 million, consistent with the typical seasonality. Recall that the timing of contracts typically make Hemlock's fourth quarter its strongest. Our tax rate for the third quarter and full year should be similar to Q2 at about 21.7%. The slides we're showing give you an additional modeling-related detail for the third quarter and the full year. In 2018, we expect to spend slightly more than $2 billion on capital expenditures with programs in every market access platform. How much more will depend on how quickly we ramp some of our investments. We will continue to keep you posted as the year progresses. Finally, we do not expect a material impact from the enacted or contemplated tariffs.
First of all, TVs are not on the current list of proposed tariffs. Second, it's our philosophy to manufacture products in the same region as our customer. This philosophy minimizes our cross-border activity and makes us less susceptible to the impact of tariffs. Third, we are not big consumers of aluminum and steel, so we expect minimal impact from related tariffs. In total, we do not expect a significant financial impact from tariffs. In closing, our second quarter results underscore that we're well-positioned and on track for the second half of our four-year strategy and capital allocation framework. We now expect an even stronger 2018. We expect to reach approximately $11.3 billion in full-year sales, with second half capacity and margin expansion. We expect continued growth in Optical Communications, Specialty Materials, Environmental Technologies, and Life Sciences.
As we've said, the display pricing environment is the best in more than a decade, and we expect to reach the important milestone of year-over-year mid-single-digit price declines in Q3. Other progress on the framework included returning $829 million to shareholders in the second quarter of 2018, for a total of $10.8 billion since the framework's introduction. We're also investing to position our businesses to meet short and long-term sales growth opportunities. Putting it all together, as we invest $10 billion to drive growth and extend our leadership, we are rewarding investors by returning more than $12.5 billion, which compounds the benefit of our future growth for long-term shareholders. With that, let's move to Q&A. Ann?
Thanks, Tony. Our operator, we're ready for our first question.
Mehdi Hosseini, please go ahead. Mr. Hosseini, your line is open.
Yes. Sorry, I have a problem with my phone. Thanks for taking my call. I want to go back to the comment regarding Gorilla use in auto. It's encouraging to see investment taking place, especially in Hefei. How should we think about incremental revenue contribution? It would be great if you could give us some milestones, looking into the next year and 2020. I have a follow-up regarding display. You talked about the best pricing environment, I think you said ever. When I hear the best pricing environment, it kind of makes me worried because can it get even better from here, or can it roll over from here? It would be great if you could elaborate how you see the sustainability of the current pricing environment. Thank you.
Let's start with your first question on Gorilla and auto. We're not quite ready to give insight onto how much revenues we'd expect next year in Gorilla and auto. What I will say is we've already got awarded business for hundreds of millions of dollars spread out over time to certain platforms. How that timing breaks down, what our ability to supply will be relative to demand, all those things are things we're working through. We're not quite ready to cycle that and figure out exactly when that's going to be delivered for each vehicle platform. We're going to try to get there as we work through the end of this year, so we can be helpful to you going into next year.
Mehdi, let me take your question on display pricing. We feel really good about display pricing and the trends that we've seen.
It is the best pricing we've seen in more than a decade, we expect to hit the important milestone of mid-single digit year-over-year declines in the third quarter, we think that improvement trend continues into 2019. There's really three reasons for that. The first, we have supply and demand in balance or even tight from a glass maker standpoint. Secondly, our competitors face profitability challenges at current pricing levels. Therefore, we expect their price declines will slow further as they try to remain profitable. The third item is LCD glass manufacturing requires ongoing investments. To generate acceptable returns on those investments, glass pricing will need to improve further. Overall, we feel very good about where we are. We really don't need everything to continue to improve and improve.
What we need to do is just that rate of decline to continue to slow, and as long as that rate of decline continues to slow, our productivity will more than offset those price declines. That's what we're aiming for.
Very helpful. Thank you.
We have a question from Vijay Bhagavath with Deutsche Bank. Please go ahead.
Hey, good morning. Hey, Wendell, I have a bigger picture question. The company has been investing in multiple capital expansion projects. I could count to maybe 20, and then I gave up. My question is: You're going through this kind of meaningful investment cycle. What's the timeframe you have in mind for subsequent investments in manufacturing capacity expansion, and then the harvesting time when you start monetizing these investments? Thanks.
Vijay, that's a great question. First of all, you're doing a good job on counting, right? We do have over 20 significant plant expansions, including a number included in that or a number of greenfield builds. We are in this pretty intense operating and capital investment cycle. Here's the good news. I think you're going to start to see the harvest begin now. We expect that we're in an inflection point in this quarter
That you're going to see growing sales from those capacity investments and expanding profitability from them. I do not think we need to wait long. I think we're going to start seeing that right in quarter three and quarter four and beyond. Is that responsive to your question, Vijay?
You know it does. Yeah, thanks, Wendell. Yeah.
Our next question is from Steven Fox with Cross Research. Please go ahead.
Thanks. Good morning. Just on the capacity expansions to date and looking ahead, Wendell and Tony, you mentioned a few times that you have committed customer support for a lot of these expansions. Can you just give us an idea of how you're managing that risk? Obviously, the customer forecast can change going forward and how that would affect you. Secondly, how do we get comfortable with the idea that what you went through in the first half of the year was unique, and we don't see another sort of mini capital burst next year or the year after as you continue to innovate? Thanks.
I'll take the first one, and Tony can address the second. We mitigate our risk with these investments a number of different ways, and it really depends on the business and the customer relationships. Sometimes we actually insist that the customer fund or put their money by our side in our capital. That significantly mitigates our shareholders' exposure to any overcapacity risk. Another way we do it is with long-term contracts with firm levels of revenue commitment. Sometimes those are very public, sometimes they're not. The best example of this would be what you saw from Verizon, with their long-term commitment to a revenue from us for $1 billion to help underpin that investment in fiber and cable. We have all sorts of variations really in between.
Our core philosophy here is, since what we do is so important to our customers, we want to do it in tandem with them. Now, that doesn't mean that our customers are always right and that the demand always comes in as we both anticipate. It does mean that we're sharing the risk in an equitable way that allows us to provide our unique products and ability to supply, to help make their vision for what they're trying to deliver in their business model possible.
I think from a going forward basis, Steve, I think the important thing to keep in mind is that we're going through a period where we're seeing growth in all of our market access platforms. The good news is that that growth is showing up right now. As Wendell said, the inflection point is today, and our second-half revenue is going to be annualized at closer to $12 billion as opposed to the first half closer to $10 billion. We're seeing very significant growth, and the payoffs are really happening in the near term. As we look forward, of course, we're going to continue to invest where that growth is. I think the probabilities of all of our market access platforms growing at the same time is probably less than what we've experienced right now.
On top of it, whatever that investment is, it's going to be on a much bigger business than what we were even six months ago. As we look through both of those things, I think we feel pretty good about how we think about that on a going-forward basis.
Great. That's really helpful. Appreciate it.
Question is from Samik Chatterjee with JPMorgan.
Hi. Good morning. I just wanted to start off with the display glass segment, and you mentioned you expect pricing to continue to improve in 2019. What are you hearing from your panel maker customers because panel prices have been down significantly in 2Q? Are you expecting any sort of cutbacks in capacity from them that might limit sort of growth in area in 2019? Then I had a minor clarification on the gross margin guidance for the second half. I think the language you used last quarter was that gross margin would exceed 42% on a quarterly basis in the back half. Today, I think you mentioned 42%. Is there any change in the gross margin expectation for the back half? Thank you.
No, there's no change in the gross margin expectations for the back half. We feel very good about bringing the capacity on and the expansion that we're going to see versus what we've performed in the last three quarters. In terms of from a panel maker standpoint, at the end of the day, what really matters here is the retail demand, and the retail demand has been very strong. As we mentioned, viewing area was up over 20% on a year-over-year basis in the second quarter. We're seeing indications from panel makers that they're buying panels to prepare for what is really the big season, which is in the fourth quarter, and that's happening right now. We expect panel maker utilizations to stay about where they have been in the first half of the year. That's going to translate to a strong glass demand.
We expect the market to be up in the mid-single digits from a glass standpoint. Of course, we'll grow faster than that because of the ramp of the Gen 10.5 factory at BOE.
Great. Thank you.
Our next question is from Rob Cihra with Guggenheim Partners.
Thanks very much. Just on Gorilla Glass, I know you noted you're benefiting from the increase in content per phone, like with the double-sided, which is great. I believe you also get a price premium when you launch something like Gorilla Glass 6. I'm just wondering, I guess, first, how much the Gorilla Glass 6 price premium, I mean, is that a noticeable help in the second half? More broadly, it seems to me, and I'm not even sure if it's the case. It seems that Gorilla Glass pricing has been better than it was a couple of years ago, where it was pretty brutal, and I'm just wondering, I mean, is that the case, and has Gorilla Glass pricing stabilized? If that's the case, why? Thank you.
You are correct in that Gorilla Glass pricing trend has been very good. What's causing that is been a really strong cycle of innovations from us, and those innovations are yielding much better products. Customers value those products more and are willing to give us a higher price for them. You are noticing in the numbers, that fundamental strategy playing out. I'm sorry, but I'm not willing at this time to give you specific guidance on Gorilla Glass 6 pricing. That'll be between us and our customers, and shown to you shortly. I think you're correct on the overall trend, Rob.
Great. Thank you very much.
Our next question is from Rod Hall with Goldman Sachs. Please go ahead.
Good morning, guys. Thanks for the question. I just wanted to come back to this auto glass plant in Hefei and ask what you guys think the utilization of that plant is likely to be once you get it built. I mean, are you expecting it to be mostly utilized, or do you think that it just incrementally gets utilized over time, and you just kind of hit a point where you need capacity? Then secondly, I noticed the R&D to sales guidance is up a little bit. I just wanted to double check what's driving that, why you decided to make that slight change in R&D to sales. Thanks.
Let me address the first one. I'll leave the second one for Tony Tripeny. Rod Hall, what's happening to us is, as we've shared previously, is the demand for our innovations in auto glass interiors has surprised us in a positive direction. As a result, at this point in time, we're having a difficult time keeping up with what our customers want us to do. If we could have had this plant six months earlier be up and running, we would have it full. We expect the utilization to run pretty high. I think it's just worth pausing here a moment, though, so you understand what type of capacity this is. You shouldn't think of this as melting capacity. We don't need to add any Corning Gorilla Glass manufacturing capacity to facilitate our entry into the automotive glass market.
We plan to meet all that demand with our continued productivity improvement on the fusion platform for today's Corning Gorilla Glass business as well as display. What this plant is going to do is going to be applying some of our vapor deposition technology to be able to do advanced optical treatments. It's going to be able to do shaping of the product. It's going to be able to do the decoration of the product, cutting it exactly the right way. It's the value add part on top of it. As a result of that, you're not going to see the typical utilization effects you'd be used to thinking about in a big-time glass factory. The capital intensity of this is much less. That's what this capacity is. Is that responsive to your question, Rod Hall?
Thanks, Wendell P. Weeks. That's super helpful. Appreciate it.
Rod, on the RD&E, there really isn't a change there. I mean, we expect to spend about the same amount in the second half as we spent in the first half. The actual spending always depends a little bit on pacing of projects, but the amount that we're guiding is in the normal range that we've been guiding for a while.
Great. Okay. Thanks, Tony.
Our next question is from George Notter with Jefferies. Please go ahead.
Hi, guys. Thanks very much. I guess I wanted to dig into display segment margins a bit. Yeah, I heard what you said certainly on the BOE expansion ramping and now the reskinning of tanks and improved utilization. Where do you think we could get segment net income margins to go to? If I look back at those numbers, I think there's some 30% numbers if I look back to last year and the year before. If I go way back, I can even see 40% segment net income margin type numbers. Where do you think we can go with these improvements in utilization and BOE? Thanks.
Well, George, I think it's important to realize that what we're all about in Display is stabilizing the profitability in that business. We do that with continued
What we've seen from a pricing standpoint, as Wendell said, we don't need any further pricing improvements than where we are today. With that, along with volume growth, along with our manufacturing improvements, we're all about getting that bottom line to essentially be the same. That's what our objective is. That also means that sales will be about the same, once you get to that point, the operating margin will be about where it is today. Obviously, that's a significant improvement over the last few years, where we've seen that decline for several years, where we've seen significant decline in Display profitability.
Great. Thank you. Our next question is James Faucette with Morgan Stanley. Please go ahead.
Thank you very much. I guess maybe I'd relay probably one of the most common questions we've gotten recently, and that has to do with capital allocation. As we kind of trod towards the end of 2019, we can see how that's likely to be divided up, et cetera. At what point should we expect to see a new plan or further forward outlook on capital allocation? Can you give us a general outline in terms of your preferences for dividends versus buybacks, et cetera? Thanks.
Yeah. I think, James, it's important to note that we have more than a year to go in our current framework. What we're really focused on is delivering our four-year plan. The good news is all of our existing businesses, especially Displays, are generating strong operating cash flow. We expect that to continue. The other piece of good news is we have multiple large opportunities for growth in all of our market access platforms. We're going to continue to invest in those opportunities, especially those because they generate attractive return on invested capital to our shareholders. It's been our practice is that anything beyond that, we're going to return to our shareholders. That's how we think about it going forward.
In terms of specifics and how things are going to look beyond 2019, we're just going to wait until we get closer to the end of the current plan, before we share the next set of specifics.
Great. Ann, we have time for a couple more questions. Thank you. Our next question is Wamsi Mohan from Bank of America.
Yes, thank you. Good morning. Wendell, I was wondering if you can talk a little bit about the dynamics in Specialty as it pertains to Gorilla. Some of your larger smartphone customers are not showing as much cyclicality as in prior cycles. I was wondering if that is giving you more supply chain visibility as it pertains to Gorilla. Is it changing the nature of lead times for Gorilla?
I think that's an excellent question. We have noticed some of those trends that you are outlining. They just haven't been around long enough for us to be able to say with a high degree of confidence that we see a strong improvement in visibility. That's the main effect, as you know, just tends to be in which quarter we actually tend to see the sale. It doesn't really impact us from a long-term financial standpoint, but it certainly is valuable from an operational standpoint. More to come on this topic. If this continues, then I think your logic is very sound. It needs to continue further, for us to establish good, strong mathematical modeling and conclusions.
Thanks, Wendell. If I could follow up just with one quick question on TVs, I'm sorry if you already addressed this. I was wondering, given the panel price declines and the magnitude of those panel price declines, how stimulative has that been to large screen TV demand? What are you expecting for retail sellout trends in the back half of the year? Thank you.
Yeah, Wamsi, I think it's been quite stimulative, it's been very strong from a retail demand standpoint. Glass viewing area was over 20% in the first half of the year, we expect it to continue to be very strong in the second half of the year. That's why we're quite confident that the glass market will grow mid-single digits on a year-over-year basis, will grow faster than that because of the ramp of our BOE Gen 10.5 factory.
Just to build on that, I think one of the main things that people can lose sight of is, in the end, what really matters is how many television sets people buy, right? How much is sold through the whole system. We've certainly been in a cycle where the panel market went from incredibly high utilization and rising prices, then I think that probably caused television demand to be a little suppressed from where it would want to be. Now, we've been through another cycle, like you're seeing with display panel prices having fallen, now flowing through to the end customer. I think this ebb and flow will continue to work its way out. We really like the sell-through data we're seeing.
Of course, panel prices will continue to stabilize and improve over time, and that in turn, of course, that the glass supply and demand dynamics continue to work towards a path of us improving our pricing performance year by year. That's sort of the way we take a look at the industry overall.
Thanks so much for the call. Appreciate it.
Our last question is Joseph Wolf with Barclays.
Thank you. Just a question, I guess, a continuation a little bit on the mobile market. Given some of the move to OLED and Corning's participation in both parts of the market, just can you give us some perspective on what you're seeing on the design side? There's been some talk about flexible applications, and while I know there's nothing customer specific you can share, can you talk about what flexible designs might mean for the Gorilla Glass cover market?
First let's do OLED, then we'll do flexible. As you know, we made a pretty significant amount of innovation effort to put us in a spot to be a very strong supplier into the polyimide OLED market. For those of you on the call who don't know, even though the polyimide OLED isn't made of glass, to make it, you consume a lot of glass. Actually, you consume more glass than is consumed in making a display of the same size using active matrix LCD technology. It's special glass. It's glass we developed for that application. With that being said, that I think is what we predicted, I think, quite accurately, that we could see that becoming, even though it's a small market, a significant force for mobile consumer electronics devices.
What has been in the press really now for a number of years, it's been hyped for a number of years, is the idea of a truly flexible device, which is different than a flexible display. What the idea here is, could we basically make something small that then you could fold it out and it would become something big, and that therefore you could fit more display area in a smaller volume area. That has real interest. We've been engaged for a number of years in trying to solve some of those really hard technical problems to be able to make a product that bends to very tight bend radius, but at the same time, when something is dropped on it or it experiences any sort of sharp event, that it doesn't damage easily or scratch easily.
These two things, in terms of material science, tend to push opposite from one another. That has been the core of our innovation focus. I think that ultimately, if foldables are going to be important, we're going to need to solve that problem for the cover. There's still problems to solve in the display, but ultimately, we'd have to solve that problem. I don't think it's solved yet. I think some of the first devices you'll see to try to market out will be products that are compromising on durability in one direction or the other. I think it's just the stage of the tech, and people will want to introduce it to get a feel for will consumers really get interested in it? Can they make even a form factor that's compelling? These are really big questions.
At the core, we haven't yet seen a cover material out of any material that combines all the required attributes for this to become a significant device. It takes a good amount of effort on our part. We're still working on it. We're working closely with our mobile consumer electronics customers. They really want us to invent something, but we're still on it. Sorry for the long answer.
No, that's very helpful. I will leave it at that. Thank you.
Thanks, Joseph. Thank you, Wendell. Thank you all for joining us this morning. Before we close, I wanted to let everyone know that we will be at the Jefferies Semiconductor, Hardware, and Communications Summit on August 30th and the Deutsche Bank Technology Conference on September 12th. We'll also be posting some virtual presentations and webcasts on business topics. Finally, the web replay of today's call will be available on our site starting later this morning. There also is a telephone replay available for the next two weeks, and you can contact IR for the details. Once again, thank you all for joining us. Ann, that concludes our call. Please disconnect all lines.
