Abstract

BENDABLE GLASS STACK ASSEMBLIES , ARTICLES AND METHODS OF MAKING THE SAME A glass element having a thickness from 25 µm to 125 µm, a first primary surface, a second primary surface, and a compressive stress region extending from the first primary surface WRDILUVWGHSWKWKHUHJLRQGHILQHGE\DFRPSUHVVL YHVWUHVVı,RIDWOHDVWDERXW03DDWWKH first primary surface.
