Abstract

A strengthened glass article having a central tension that is below a threshold value above which the glass exhibits frangible behavior. The central tension varies non-linearly with the thickness of the glass. The glass article may be used as cover plates or windows for portable or mobile electronic devices such as cellular phones, music players, information terminal (IT) devices, including laptop computers, and the like.

Description

[0001] The patent application for the present invention is that the international filing date is August 7, 2009, the international application number is PCT / US2009 / 004531, the application number that entered the Chinese national phase is 200980135969.7, and the invention title is "strengthened glass product and its manufacturing method" Divisional application of invention patent application.
