Corning unveils its improved Lotus XT Glass
Corning has announced its latest glass substrate for high performance LCD and OLED displays named Lotus XT Glass. Lotus XT Glass is the next generation of Corning’s Lotus Glass, which was unveiled back in 2011.
The company boasts increased brightness, higher resolution and lower power consumption for devices making use of its new Lotus XT 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 XT 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.
Second-generation composition features host of new capabilities
CORNING, N.Y., May 16, 2013 – Corning Incorporated (NYSE: GLW) today announced the commercial launch of Corning Lotus(TM) XT Glass, a second-generation glass substrate specially formulated for high-performance displays. The company will feature its latest specialty glass innovation – alongside its other advanced glass technologies – in its booth (#801) at the Society for Information Display’s (SID) Display Week in Vancouver, British Columbia, May 21 – 23.
Lotus XT Glass features best-in-class total pitch variation, which is integral to efficient panel manufacturing. Essentially, total pitch – usually measured in microns or parts per million (ppm) – is the distance features move during panel processing.
“If you can predict the amount the glass shifts, then you can account for this movement. Deviation – or variation – from this predictable movement can ultimately result in yield loss,” said John P. Bayne, vice president and general manager, Corning High Performance Displays. “Lotus XT Glass is designed to have improved thermal and dimensional stability over higher temperatures, generating higher yields for our customers.”
The Corning Lotus Glass platform enables organic light-emitting diode (OLED) displays and liquid crystal displays (LCD) that use either low-temperature poly-silicon (LTPS) or oxide thin-film transistor (TFT) backplanes. The result is an energy-efficient, immersive display device that features high resolution, fast response times, and bright picture quality.
In addition to Lotus XT Glass, the Corning booth will feature each of its advanced glass technologies, including: Corning EAGLE XG® Slim for a-Si displays; Corning® Willow(TM) Glass, the company’s ultra-slim, flexible glass; and Corning® Gorilla® Glass 3 with Native Damage Resistance(TM). Corning experts will provide daily demonstrations of Gorilla Glass 3, the industry-leading, damage-resistant cover glass. Attendees should consult booth staff for exact times.
Display Week attendees will also have the opportunity to hear several of Corning’s technology experts deliver presentations at the conference.
“Display Week is a time to take stock of the industry and its future,” Bayne noted. “The industry is changing, and Corning believes each of its innovative glasses helps solve tough technological challenges – advancing displays even further.”
