3 Agenda Glass integral in thinner and more touch capable devices Cover Glass to protect and enable touch Corning Gorilla Glass 2 thinner and better touch capability Corning IOX-FS Corning Willow TM Glass the next generation Tomorrow: roll-to-roll/flexed display; today: better touch sensor Durable/combined with Corning Gorilla Glass LCD goes thin Corning EAGLE XG Slim 0.3 mm up to Gen 6 High performance displays have unique needs Corning Lotus TM Glass 3

4 What will a touchable and thinner future look like? 4

5 The future may be here already: all these devices are getting thinner; many, if not all, also touch capable Amazing time in the display industry Higher resolution Brighter Faster response Lower power consumption Thinner Lighter Entrance of smartphones and slates Touch-screen interface 5

6 As we go to a thinner form factor: the entire display stack has opportunity for reducing thickness or eliminate BLU altogether (OLED) Reduce LED chip size & light guide thickness Reduce mother substrate thickness or chemically thin panel Reduce touch sensor thickness or integrate sensor on cover glass ( sensor on lens or one glass solution ) Reduce cover glass thickness BLU LCD cell touch sensor cover glass 6

7 Glass technology for evolutionary display trends Slimmer Devices Ubiquity of Touch Slimmer Devices Better Touch Sensors Slimmer Devices High Resolution 7

8 Failure Load (kgf) Corning Gorilla Glass 2 provides >25% increase in surface damage resistance or enables up to 20% thickness reduction New Product Current Product Abraded RoR Data ** At any thickness, Gorilla Glass 2 shows a >25% higher load-to-failure after abrasion Gorilla Glass 2 enables thickness reduction of 10~20%* with equivalent damage resistance 150 Gorilla Glass 2 can reduce strengthening time by 10-15% Fully compatible with existing parts manufacturing processes mm Glass Thickness (mm) * Actual thickness reduction depends on factors such as initial and final part thickness, glass processing, frangibility and device design **error bars are 95% confidence intervals 8

9 Corning Gorilla Glass 2 has superior scratch performance by optimizing glass chemistry & structure 9

10 Cover glass also protects & better enables large touch displays Corning Gorilla Glass enables displays that engage consumers Thin Corning Gorilla Glass is a better solution for interactive displays Tough / Durable Industry leading toughness and damage resistance Weight Reduction Allows for significant weight reduction, which enables sleek design options as well as transportation savings Touch / Performance Aligns image and touch by addressing the issue of parallax Clarity / Optical Performance Delivers beautiful, clear images with higher optical sensitivity **Photo Courtesy of Perceptive Pixel 10

11 Parallax (mm) SNR Improvement over 1.3mm Improved touch accuracy for a responsive customer experience Thin Corning Gorilla Glass: 75 0 Reduces parallax and improves touch accuracy Makes a big impact particularly at steep viewing angles Is critical for high resolution touch panels Yes No Yes No 5mm Soda Lime (SLG) 1mm Gorilla Glass Parallax difference between direct bonding and air gap Direct Bonding; 0.7 mm GG; 0.1 mm glue Air Gap; 4 mm SLG; 2 mm air gap Can exhibit up to 40% more touch sensitivity than thicker soda lime glass based on parallel-plate capacitor approximations 80% 70% 60% 50% 40% 30% 20% 10% % Sensitivity Improvement over 1.3mm Glass Angle ( ) 0% Cover Glass Thickness (mm) 11

12 Another Cover Glass Option: One Glass Solution (OGS) enables thinner devices One glass solution combines strengthened cover glass and the ITO sensor into one sheet - allowing for large scale, full-sheet processing of touch screens Benefits: Cost reduction Weight reduction Reduced stack height Streamlined manufacturing & supply Discrete Touch Module OGS Touch Module 12

13 Corning IOX-FS delivers superior performance over soda lime glass for applications using OGS OGS is based on single cover glass substrate with ITO pattern underneath Prior to Corning IOX-FS, using OGS required tradeoffs in device durability 5x Surface Damage Resistance Thinner devices Higher in-field durability Design flexibility Corning IOX-FS (Benefits over soda lime) 7x Indentation Threshold 2x Edge Strength Fewer scratches in use Higher in-field durability Design flexibility Higher Transmission Brighter displays Better color on high resolution displays 13

14 The next step: thin and flexible glass substrates for ultra-slim displays Corning Willow TM Glass is thin enough to be flexible while retaining its superior glass attributes Combines inherent benefits of glass with a mechanically bendable form factor, enabling continuous and costefficient processing Enables thinner, lighter, and potentially flexible electronic devices that deliver high performance at a lower cost Thin & Light Devices Thin & Light: Touch sensor mm 0.1mm Color Filter mm 0.1mm Backplane mm 0.1mm 20-40% z-height & weight reduction Roll-to-roll processing enables cost efficient production Native thin avoids thinning cost for sheet-to-sheet processes 14

15 Corning Willow Glass is for substrate and Corning Gorilla Glass is for cover Corning Gorilla Glass Corning Willow Glass as substrate Touch sensor Color Filter TFT backplane 15

16 Combined with the right cover, it is flexible and durable for touch capable devices 16

17 As portable displays, like tablets and notebooks evolve, Corning s a-si substrates evolve with them Emerging mobile applications are driving increased demand for thinner, lighter display panels In 2011, we tested every available tablet and found that 93% used thin glass ( 0.3 mm). Average thickness for handheld devices is even less than it is for tablets EAGLE XG Slim glass substrates help panel manufacturers meet this demand in a more cost-efficient and environmentally friendly way To this From this Photos: Courtesy of Intel EAGLE XG Slim helps enable the vision Now at 0.3mm up to Gen 6 17

18 Corning EAGLE XG Slim: better surface uniformity and naturally thin no chemical processing Fusion drawn surface (bottom left) vs. chemically thinned surface (bottom right) from 0.5 to 0.3 mm Optical uniformity issue may arise by placing thin films / polarizer on glass surface containing large peak-to-valleys Surface topology variation increases by ~ two orders of magnitude Panel without any optical defects Optical defects shown as lines in panel 18

19 But high performance displays including some tablets and smartphones require a different specialty glass 600 C LTPS and Oxide-TFT use higher temperature processes Typical Thermal Cycles a-si Ox- TFT p-si Placing tougher requirements on the glass Glass must be dimensionally stable Glass must be flat Glass must have pure & pristine surface 400 C Time 19

20 Compaction Rate (PPM/ C) Corning Lotus Glass minimizes the pattern errors that hamper high resolution panel manufacturing Corning Lotus Glass substrates show reduced variability due to thermal and device nonuniformity A-Si Glass Variability can come from both thermal and film non-uniformity sources Corning Lotus Glass increases process window for future process optimization in both mobile and large size high resolution displays Corning Lotus Glass Hold Temperature ( C) 20

21 Even the finest sub-micron scratch can result in yield loss with the reduced feature size in high-ppi display 21

22 Millimeters Corning Lotus TM Glass: Not only optimized for high performance displays but getting thinner as well Today, Corning Lotus Glass is available in thicknesses ranging from 0.7mm 0.5mm. But as both portable and large size high performance devices get thinner, the Lotus family of glasses will get thinner as well mm 0.5mm 22

23 Corning Innovations Information Delivery System Historically, Corning has a long tradition of delivering enabling glass technologies for the Information Age Radio Black and White TV Color TV High-Definition TV 1920s 1940s 1960s 1980s 2000s 2010s Vacuum Tube Envelopes CRT Panels and Funnels Optical Fiber AMLCD Substrates Corning Gorilla Glass 23

24 The last word Touch becoming primary user interface Thin becoming key requirement for consumers but also to better enable touch The right cover glass and display glass substrates can provide devices that combine superior touch capability, previously unheard of thinness and amazing optical clarity The glass matters The glass you use matters Corning Glass works 24
