Corning Launches Ultra-Slim Flexible Willow Glass

Corning announced the launch of Willow Glass, an ultra-slim flexible glass, aimed at revolutionizing the shape and form of next-generation consumer electronic technologies. According to Corning, Willow Glass will help enable thin, light and cost-efficient applications including today’s slim displays and the smart surfaces of the future. The thinness, strength, and flexibility of the glass has the potential to enable displays to be “wrapped” around a device or structure.

Corning Willow Glass can be processed at temperatures up to 500° C. High temperature processing capability is essential for today’s high-end displays, and is a processing condition that cannot be supported with polymer films. Corning Willow Glass will enable the industry to pursue high-temperature, continuous “roll-to-roll” processes – similar to how newsprint is produced – that have been impossible until now.

It will support thinner backplanes and color filters for both organic light emitting diodes (OLED) and liquid crystal displays (LCD) in high-performance, portable devices such as smartphones, tablets, and notebook computers. This new, ultra-slim flexible glass will also help develop conformable (curved) displays for immersive viewing or mounting on non-flat surfaces.

Corning Willow Glass is formulated to perform exceptionally well for electronic components such as touch sensors, as well as leveraging glass’s natural hermetic properties as a seal for OLED displays and other moisture and oxygen-sensitive technologies.

Corning Willow Glass is produced using the company’s proprietary fusion process. Advances in fusion forming have made it possible to produce glass that is 100 microns thick – about the thickness of a sheet of copy paper. Even at that thickness, it provides hermetic sealing to sensitive components, while also providing excellent optical, thermal, and surface properties.

Corning is currently shipping samples of its Willow Glass to customers developing new display and touch applications. Check out the video below showing the roll-to-roll processing of the Willow Glass.
