Transparent substrate with diffuser surface
First Claim
Patent Images
1. A faceplate for mounting to a cathode ray tube screen, said faceplate comprising:
- a glass substrate, said substrate having inner and outer surfaces;
a reduced gloss, high resolution diffuser surface coating comprising a metal oxide disposed on said outer surface of said substrate; and
an index matching medium on said inner surface of said substrate for contacting the cathode ray tube screen when applied thereto;
said diffuser surface coating having a gloss reading less than about 80 gloss units and a resolution of at least 3 lines per millimeter;
said faceplate being formed separately from the fabrication of the cathode ray tube screen and having reduced glare from ambient light without significant reduction in resolution of images from the cathode ray tube visible through said faceplate.

Abstract
A transparent substrate having a glare reducing diffuser surface coating on its outer surface forms a faceplate for attachment to a screen for a cathode ray tube or other display device. The coating has a preferred thickness of less than about 3 microns, and the substrate may include an index matching adhesive/medium for attaching said faceplate to a cathode ray tube screen. The diffuser surface coated substrate is bendable and overcoatable with functional coating such as transparent conductor and/or abrasion resistant coatings.

11. A faceplate mounted on a cathode ray tube screen said faceplate and cathode ray tube combination comprising:
-
a cathode ray tube screen; said faceplate fabricated separately from said cathode ray tube screen and including a convex, transparent, curved glass substrate having a convex outer surface, a concave inner surface, and a diffuser surface coating disposed on said outer surface of said substrate, said diffuser surface coating comprising a metal oxide and having a thickness less than about 3 microns, a gloss reading less than about 80 gloss units and a resolution of at least 3 lines per millimeter; and an index matching medium on said concave inner surface of said substrate, said index matching medium contacting said cathode ray tube screen and attaching said substrate to said screen; said faceplate having reduced glare from ambient light without significant reduction in resolution of images from said cathode ray tube screen visible through said faceplate. - View Dependent Claims (12, 13, 14, 15, 16)
