Corning has announced its latest glass substrate for high performance LCD and OLED displays named Lotus NXT Glass. Lotus NXT Glass is the next generation of Corning’s Lotus Glass, which was unveiled back in 2011, an its 2013 Lotus XT Glass.
The company boasts increased brightness, higher resolution and lower power consumption for devices making use of its new Lotus NXT Glass. This has been accomplished by Corning’s focus on to maintaining its glass’ total pitch variation performance in a wide range of manufacturing temperatures. The glass is said to maintain its performance with both low-temperature and high-temperature LTPS and oxide TFT processes.
Pitch Variation is essentially the distance that display components, such as color filters, move during heating. These have to be lined up with the backplane transistors and glass that varies too much has to be discarded. Corning says that variation is improved by up to 60 percent over its competition. Production yields should be improved thanks to these changes, which should help device manufacturers reduce their costs. You can see more about the improvements in the video below.
While Corning’s well-known Gorilla Glass is used to protect a wide range of smartphone displays from scratches and shattering, Lotus Glass is used within the display themselves, nestled closely to the backplane transistors and light emitting components. Improved yields will reduce the costs currently associated with higher resolution, high quality displays.
Lotus NXT Glass is now commercially available for manufacturers to make use of, although we’ll have to wait and see which device manufacturers are the first to make use of Corning’s new glass.
