Glass articles comprising light extraction features and methods for making the same

Abstract

A method for making a glass article comprising contacting a first surface of a glass substrate with a laser to produce a plurality of light extraction features having a diameter and a depth, wherein the light extraction features produce a color shift delta y of extracted light whered delta y < 0.01 per 500 mm of length. A glass article as described can comprise a first surface and an opposing second surface, wherein the first surface comprises a plurality of laser induced light extraction features, and wherein the plurality of laser induced light extraction features produces a color shift delta y < 0.01 per 500 mm of length.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of priority under 35 U.S.C. §119 to U.S. Provisional Application Serial No. 62 / 314662, filed March 29, 2016, on the basis of which application is incorporated herein by reference in its entirety . technical field [0003] The present disclosure relates generally to glass articles and display devices including the glass articles, and more particularly, to glass lightguides including light extraction features and methods of making the same. Background technique [0004] Liquid crystal displays (LCDs) are commonly used in various electronic devices such as cell phones, laptops, electronic tablets, televisions and computer monitors. The growing demand for larger, higher-resolution flat-panel displays drives the need for high-quality large glass substrates for displays. For example, a glass substrate can be used as a light guide plate (LGP) in an LCD that can be coupled to a light sourc...
