Corning Continues to Innovate
It was only a few months ago that Corning's Gorilla Glass 2 was in the spotlight. Not content with resting on their laurels, they announced the new Willow glass product at SID 2012.
Willow glass in an ultra-thin flexible glass (50-100 micrometers) that is capable of supporting backplanes and color filters in LCD and OLED panels. Temperatures of up to 500-degrees Celsius (932-degrees Fahrenheit) can be endured and it can be employed in roll-to-roll applications.
According to Corning, Willow glass will be used to produce rigid OLED panels in manufacturing processes that require flexible glass (such as roll-to-roll). In the future it may produce flexible glass panels.
Willow glass is not intended to be used as cover glass (like Gorilla glass). It will typically be used in a “sandwhich” for OLED displays, which have a substrate layer, an encapsulation layer and then a much tougher cover glass.
Production is planned to start in Q3 2012 with one meter wide, 300 meter long rolls.
