Solarization resistant rare earth doped glasses

Abstract

Substantially alkali free glasses are disclosed which can be used to produce substrates for flat panel display devices. The glasses can have a loading of fluorine and ceria to achieve exemplary solarization and UV protection attributes when exposed to UV radiation. Methods for producing substantially alkali free glasses using a float or downdraw process (e.g., a fusion downdraw process) are also disclosed.

Description

[0001] Cross References to Related Applications [0002] This application claims priority under 35 U.S.C. §119 to U.S. Provisional Application Serial No. 62 / 440,042, filed December 29, 2016, which application is based upon and is hereby incorporated by reference in its entirety. technical field [0003] Embodiments of the present disclosure relate to display glasses. More specifically, embodiments of the present disclosure relate to display glasses for liquid crystal displays. Background technique [0004] The production of liquid crystal displays, such as active matrix liquid crystal displays (AMLCDs), is complex and the properties of the substrate glass are important. Glass substrates used in the production of liquid crystal display devices need to have their physical dimensions tightly controlled. Down-draw sheet drawing processes, particularly the fusion process described in US Patent Nos. 3,338,696 and 3,682,609 to Dockerty, can be manufactured without the need for co...

Problems solved by technology

Conventional attempts to add UV light absorbing ions to glass have been limited by the inability to add enough UV absorbing ions to produce sufficient UV absorption without imparting color to the glass
