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.

Corning says that it will take at least 3 years before we'll start seeing flexible displays based on its Willow glass. Corning sent samples of this glass to companies back in June 2012 hoping that products will arrive in 2013, but it seems that manufacturers find it hard to adopt their processes for the flexible glass.

Willow glass (announced during SID 2012) is an ultra-slim (50 um and 100 um) flexible glass that can support backplanes and color filters in both LCD and OLED panels. Willow glass can withstand temperatures up to 500 degrees Celsius, and can be used in R2R production processes (ITRI developed a full R2R process with Corning).

A couple of months ago we posted about a rumor claiming that Apple is working on a PMOLED Bluetooth smartwatch. Now the New York Times and the Wall Street Journal are both posting a similar story, which actually gives this rumor some credibility. This time they say that Apple is working with their long-time manufacturing partner Hon Hai Precision Industry.

We're not sure what is meant exactly by "curved glass". We have seen devices with curved rigid glass before (for example the Nexus S). The New York Times speculates that the new iWatch will use Corning's flexible Willow glass (shown in the video below) - and so probably the whole display will be curved, maybe something similar to the prototypes Samsung unveiled at CES.

Nanomarkets posted an interesting article on flexible glass (based on their Flexible Glass Market report). Basically they're saying that the opportunities for flexible glass have never been better, and they forecast that the market in 2013 will reach $125 million, and this will grow to over $2 billion before 2020.

Interestingly Nanomarkets says that the OLED market will start adopting flexible glass in 2013 - with $4 million in revenue (this will grow to $280 million by 2020). Perhaps Nanomarket thinks that Samsung will adopt flexible glass in their first YOUM flexible OLED based panels?

Taiwan's Industrial Technology Research Institute (ITRI) claims that Taiwan can still compete with Korean panel makers (Samsung and LGD) in the flexible AMOLED market. The institute says that help from the Taiwanese economics bureau will be required. Upstream suppliers will need to ramp up their development effort and boost production facilities and materials.

Samsung had plans to release their first plastic-based flexible OLEDs in 2012, but this has been delayed to early 2013. LG Display hopes to start flexible OLED production towards the end of 2013.

ITRI announced it has developed a full roll-to-roll process on 100um flexible glass substrates - they say they're the first in the world to do so. ITRI has been collaborating with Corning on this technology, and they are using Corning's flexible Willow glass, unveiled at SID 2012.

ITRI and Corning developed specially designed R2R machines that produce touch panel modules on Corning Willow Glass, a flexible display-grade glass substrate. ITRI are now looking for companies that sell this technology - which can be used for OLED display and lighting panels, solar panels and more applications.

Corning's major announcement at SID was the new Willow glass product. This is an ultra-slim (50 um and 100 um) flexible glass that can support backplanes and color filters in both LCD and OLED panels. Willow glass can withstand temperatures up to 500 degrees Celsius, and can be used in roll-to-roll production processes.

Corning says that in the near future Willow glass can be used to produce rigid OLEDs panels in processes that need flexible glass (such as roll-to-roll), and in the long term it may also lead to actual flexible panels based on glass. Glass have several advantages over plastics, mainly that it's a better barrier and it can result in better displays in terms of resolution, backplane speeds, etc. However the major disadvantage is that it can be shattered, unlike plastic-based displays.

Back in April 2011 Corning produced a nice video called A Day Made of Glass, showing future designs made with durable, transparent and even flexible glass displays. Now Corning is back with a sequel, showing the same family but with some new ideas in the home, car, classroom, outdoor and work environments:

A lot of these displays can be achieved with OLEDs, although OLEDs aren't specifically mentioned in those video. Just a few days ago Corning announced an OLED glass joint-venture with Samsung. Corning also released an unpacked version of this video- that includes explanations about the technology shown in the video:
