Flexible Glass – Current technology status and applications
Precision glass has some unique attributes which enabled many applications where glass is used as a substrate or superstrate materials. Display and Photo Voltaic (PV) devices are two obvious application of rigid flat glass where both of these applications are demonstrated. Flexible substrate and superstrate is the next generation technology that is driving the new application opportunities, such as, flexible display and PV. While polymer films are the obvious choice for flexible substrate or superstrate because of ease of low cost manufacturing through roll-to-roll (R2R) processing, thermo-mechanical stability and hermiticity remains as key challenges to overcome. Flexible glass, like Corning(R) Willow(R) Glass, overcomes these challenges while enables low cost R2R processing. This presentation will summarize current state of the flexible glass technology and discuss some of the latest applications of flexible glass as substrate and superstrate.
