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:
DSCC posted an interesting blog post in which the company shares its information on Samsung's upcoming foldable smartphones.
First up is the Galaxy Z Flip 3 (which is a bit strange as there's no Galaxy Z Flip 2). This new phone will feature an Ultra Thin Glass cover - which for the first time will not be exclusively produced by SCHOTT. This time Corning will supply some of the UTG for Samsung. According to DSCC, Corning’s UTG will be processed by Korean supplier eCONY. This is interesting - a while back it was reported that Samsung Electronics halted its UTG project with Corning.
Samsung Electronics started to adopt ultra-thin glass covers for its foldable AMOLEDs, instead of polyimide, as it says UTG offers higher durability. Samsung currently uses Samsung Display's UTG, and according to reports it aimed to develop its own solution in collaboration with Corning
A new report from Korea suggests that Samsung Electronics has halted this project as it realized it should better increase the efficiency of its current supply chain (i.e. Samsung Display's UTG solution) and secure lower prices. It may be that this decision is only temporarily, as it is likely that Samsung Electronics is still aiming to also increase the durability of its UTG covers and not just decrease costs.
Samsung started to adopt ultra-thin glass covers for its foldable AMOLEDs, instead of polyimide, as it says UTG offers higher durability. In the Galaxy Z Flip, Samsung used a UTG cover produced by Korea-based Dowoo Insys, who processes Schott's ultra thin glass for Samsung Display.
In April 2020 it was reported that Samsung Electronics wants to develop its own UTG cover technology, as as it feels that Samsung Display's UTG is still not robust enough and the company also wants to increase production yields and reduce costs. Now there are new reports from Korea that say that Samsung Electronics is collaborating with Corning in this new UTG project.
In March 2018 OLEDWorks launched its first flexible OLED panels, branded as BendOLEDs. The company now announced that the panels are now commercially available - and rebranded as LumiCurve Wave, which is the first panel in OLEDWorks LumiCurve product family.
The LumiCurve Wave is produced on Corning's 0.1mm thin Willow Glass flexible glass substrate. OLEDWorks says that the Wave panels are extremely thin and light and deliver the superb light quality and excellent color rendering that is uniquely achievable with OLED.
Corning announced that Samsung Display is using the company's Lotus NXT glass as the carrier glass in its latest flexible OLED panels, including those that are used in the Galaxy S8 and S8+ smartphones. Both these new flagship phones also adopt Corning's Gorilla Glass 5 cover glass.
Samsung Display is producing its flexible OLEDs on a flexible polyimide substrate, and the Lotus NXT glass is used as a carrier glass during production (it is removed at the end of the process).
In April 2016 Corning and OLEDWorks launched an OLED lighting design contest , calling designers to integrate thin, lightweight and cool-to-the-touch OLEDWorks lighting panels into functional luminaires that are practical yet creative.
Corning and OLEDWorks now announced the winners of this content - Matthew Boyko, Mike Garner from MSG Lighting, and Sadyr Khabukhayev. The winners were awarded $10,000 each for their innovative lighting luminaires – which ranged in design from horizontal lighting arrays, to the integration of OLEDs into triangular storage modules, as well as a creative way to install OLED panels.
According to Digitimes, Taiwan's ITRI is building a Roll-to-Roll (R2R) R&D pilot line to produce flexible OLED lighting panels. The line will be operative by 2017, and will be able to produce about 700 panels per month.
ITRI's new OLEDs will be based on flexible glass substrates. Back in 2012 ITRI collaborated with Corning to develop a full roll-to-roll process on 100um flexible glass Willow glass substrates. It's likely that the new line will also use Corning's Willow glass.
Corning and OLEDWorks launched a new OLED lighting design contest - calling designers to integrate thin, lightweight and cool-to-the-touch OLEDWorks lighting panels into functional luminaires that are practical yet creative.
All proposals must be submitted by June 30, 2016. Up to five winners will be announced in September 2016 - and each will be rewarded with $10,000. The contest is open to the public, including students, emerging professional designers, and professionals working at design studios and luminaire companies.
According to reports, Samsung is gearing up to introduce their first foldable OLED smartphone device by the end of 2016, as Samsung's mobile phone unit is under pressure to innovate and recapture its lost market share.
According to an interesting report from Korea, Samsung has been collaborating with a KAIST spin-off called Solip Technology that developed a foldable glass that will be used in Samsung's upcoming foldable OLEDs. Samsung is considering placing a strategic investment in Solip as this material is a key technology for Samsung.
Corning announced that Samsung Display adopted the company's Lotus NXT glass as its OLED panel substrate. The Lotus NXT glass was announced in June 2015, and Corning reveals that that Samsung already adopted those substrates for the Galaxy Note 5's 5.7" Quad-HD (2560x1440, 518PPI) Super AMOLED display. The Note 5 was released in August 2015.
Lotus NXT improves the 2nd-gen XT glass (launched 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).
