Corning is one of the world leaders in glass and ceramics - working on these materials for 150 years. Corning is active in several markets - display technologies, Environmental technologies, telecommunications, life sciences and others.
Corning has three products aimed for OLEDs:
- Lotus Glass, suitable for high-end OLEDs and LCDs (Lotus replaced the old JADE OLED glass product)
- VITA, hermetic sealing solution for OLEDs (available for licensing only)
- Willow Glass: ultra slim (50 and 100 um) flexible glass that can support backplanes and color filters in both LCD and OLED panels and be used in R2R processes.
In February 2012 Corning announced that it will form a new joint-venture with Samsung that will produce Lotus Glass for OLED displays in Korea. That glass plant is now up and running, and Samsung is already using Lotus glass panels from that plant in their OLED smartphones and TV panels.
In 2017 Corning announced that Samsung is adopting its Lotus Glass NXT in its Galaxy S8 smartphones as a carrier glass.
The latest Corning OLED news:
Corning announced an updated version of their high-performance (LCD and OLED) display glass substrate, the Lotus NXT Glass. The new glass improves the 2nd-gen XT glass (launched exactly two years ago in May 2013) with lower total pitch variations.
The new glass has improved stability, and better total pitch variation performance. According to Corning, this enables display makers to produce more efficient displays (up to 15% lower power consumption), or higher resolution displays (by up to 100 additional pixels per inch). The Lotus NXT can also improve display production yields - by up to 1.5%. It's not quite clear if these numbers refer to the improvement over Lotus XT or other glass substrates on the market
Corning's Willow Glass will not just enable the panels to be flexible - the glass also integrates Corning's light extraction technology that will (according to OLEDWorks) enable them to double the light output from the panels.
Two new technologies seem to dominate the LCD TV market in CES 2015. First up are quantum dots TVs - which are LED backlit LCDs that include a QD film that enhances the TV's color gamut, efficiency, brightness and contrast. Sony has been producing QD TVs for almost two years, but this year we have new launches from Samsung, LG, Philips, TCL and others.
These new wave of QD TVs are Cadmium-free, which was one of the major stumbling block towards real QD commercialization. The major advantage of QD TVs is the enhanced color gamut, which is even larger than the color gamut currently offered by OLED TVs (although LG promises their OLEDs will catch up soon). LG still considers OLEDs as their future TV technology, and Merck also says that quantum-dots are not a real game changer (unlike OLEDs).
The OLED Lighting Commercialization Alliance (OLCA) was formed a few days ago in Taiwan, with an aim to make Taiwan an important OLED lighting player. The alliance will promote OLED technologies and will include members from materials suppliers to product makers.
The OLCA seems to be led by Taiwan's ITRI. Other members include Merck, RiT Display, WiseChip, Corning, Tongtai Machine & Tool and the TLFEA (Taiwan Lighting Fixture Export Association). ITRI says that more than 60 companies have shown interest in collaborating with OLCA members.
Corning and Samsung announced a complicated deal today - Corning will buy out Samsung Display's stake in their LCD glass joint venture (Samsung Corning Precision Materials, or SCP). In exchange, Samsung will receive convertible preferred shares in Corning that are valued at $1.9 billion and will acquire more shares for $400 million. If Samsung converts all these shares, they will own 7.4% of Corning.
Corning estimates that this move will add about $2 billion in annual sales and about $350 million in profit. As part of the deal, the two companies signed a new 10-year LCD display glass supply agreement. Corning will also buy other minority shareholders in SCP for about $300 million, and will also pay a special $1.4 billion dividend payment to SDC.
Corning recently announced the new second-gen Lotus XT high-performance glass suitable for OLED displays. The company has been supplying glass substrate and cover glass for OLED displays for years now. Now Corning was kind enough to participate in a Q&A session here on OLED-Info to better explain how they see the OLED market and what the future holds for Corning and OLEDs.
We talked to two Corning executives. John Bayne is Corning's High Performance Displays VP and General Manager, while Harrison Smookler is the commercial director and program manager of Willow Glass Substrates (flexible glass).
Tianma says they chose Lotus XG Glass because of the advanced properties of the glass. The company’s LTPS line is located in Xiamen, China, and has a capacity of 30,000 TFT modules, and more than 30,000 color-filter modules per month. It is the first Gen 5.5 LTPS line in China.
Corning announced today that it has been collaborating with AUO on high-performance displays, and AUO's new 5" HD720 AMOLED panels shown at Touch Taiwan use Corning's Lotus Glass. As far as I understand, they are using Corning's latest generation Lotus Glass XT.
AUO says they selected the Lotus Glass platform because of the glass substrate's outstanding thermal and dimensional stability, which facilitates efficient panel manufacturing during rigorous, high-temperature processing.
Corning announced their new, second-generation Lotus XT glass for high performance displays (LCDs and OLEDs). The Lotus XT offers better dimensional stability and can withstand higher temperatures compared to the previous version.
The new glass features better total-pitch variation (the distance features move during panel processing). All this means that using the new glass shall increase production yields and result in more precise manufacturing. The new glass can be used as substrate for LTPS and Oxide-TFT backplanes.
Samsung unveiled their new flagship smartphone, the Galaxy S4. As expected, it sports a 4.99" Full-HD (1920x1080, 441 PPI) Super AMOLED display behind a Corning Gorilla Glass 3. This phone will launch towards the end of April worldwide (on 327 carriers in 155 countries). The S4 seems to be more of an upgrade to the S3 than a revolutionary new handset.
According to previous reports, Samsung Display started producing these 5" Full-HD AMOLED panels in February at a rate of 3 million units per moth (this will grow to almost 10 million monthly units in coming months). The S3 is Samsung's best selling and fastest selling smartphone, and obviously the company hopes that the S4 will sell even better.
