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 resolution of at least about 3 lines per millimeter, 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 coatings such as transparent conductor and/or abrasion resistant coatings. Alternately, the diffuser surface coating may be applied over such functional coatings which are applied to the substrate.
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 resolution of at least about 3 lines per millimeter;
- and
- said faceplate being formed separately from the fabrication of the screen and having reduced glare from ambient light without significant reduction in resolution of images from the display visible through said faceplate.
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;
- an index matching medium disposed on said inner surface of said substrate for contacting the display screen when applied thereto;
- said coated faceplate having a resolution of at least about 3 lines per millimeter;
- and
- said faceplate being formed separately from the fabrication of the screen and having reduced glare from ambient light without significant reduction in resolution of images from the display visible through said faceplate.
