The Difference Between Willow Glass And Gorilla Glass

This article asks how the market/application for Corning's "other glass" (i.e., Willow Glass) is different than Gorilla Glass. Dipak Chowdhury, a company VP and Willow Glass program director, explains the two compliment each other in many electronics-oriented applications that require strength, durability, flexibility, touch sensor interface, etc. He describes how most touchscreen systems are currently made with four layers of glass (backplane, color filter, touch sensor, and front cover plane), and Willow can serve for all but the cover layer, where Gorilla Glass serves best. Put simply, Chowdhury says that GG provides a tough, damage resistant layer while WG is thin, light, and durable. He goes on to discuss how WG will influence electronics design. Although he cautions that WG's renown for flexibility won't immediately translate into flexible electronics, it could quickly be used in curved, custom displays that are not subjected to constant flexing. Chowdhury also discusses a specific specialty application for WG: rolls of photovoltaic roofing materials.
