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 gloss less than about 80 gloss units, 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, overcoatable with functional coatings such as transparent conductor coatings, abrasion resistant, and generally serviceable for its intended use.
Claims54
A faceplate for mounting to a screen for a display device, said faceplate comprising:
- a transparent glass substrate, said substrate having an outer surface and an inner surface;
- said outer surface of said substrate coated with a transparent conductor coating, said transparent conductor coating selected from the group consisting of doped tin oxide, indium tin oxide and doped zinc oxide;
- a diffuser surface coating disposed on said transparent conductor coated surface of said substrate;
- said coated faceplate having a gloss less than about 80 gloss units;
- and said faceplate being formed separately from the fabrication of the screen and having reduced glare from ambient light incident on said diffuser coated surface of said substrate.
A faceplate for mounting to a screen for a display device, said faceplate comprising:
