Display screen
View Patent ↗A display screen for a projection device is disclosed, wherein the display screen includes a substantially rigid translucent backing structure, and a viewing surface disposed on the backing structure, wherein the viewing surface has a frosted appearance. The display screen also may include a contrast-improving intermediate layer disposed between the backing structure and the viewing surface.
1. A front-projection display screen for a front-projection device, comprising:
a generally rigid, translucent backing structure:
a contrast-improving intermediate layer adhered to the backing structure, wherein the intermediate layer includes a black celluloid photographic film layer and is configured to improve a contrast of an image projected onto the screen in a presence of ambient light; and
a viewing surface layer adhered to the intermediate layer, wherein the viewing surface layer is formed from one of a transparent and a translucent material, and wherein the viewing surface layer includes a viewing surface textured such that the viewing surface has a frosted appearance capable of reflecting projected light for front-projection viewing.
2. The display screen of claim 1 , wherein the intermediate layer has a shaded appearance.
3. The display screen of claim 1 , wherein the intermediate layer has a generally black appearance.
4. The display screen of claim 1 , wherein the backing structure includes a sheet of glass.
5. The display screen of claim 1 , wherein the backing structure is transparent.
6. The display screen of claim 1 , wherein the viewing surface layer only partially covers the backing layer.
7. The display screen of claim 1 , wherein the viewing surface layer fully covers the backing layer.
8. A front-projection display screen for a front-projection device, comprising:
a generally rigid, translucent backing structure;
a contrast-improving intermediate layer adhered to the backing structure, wherein the intermediate layer includes a thermochromatic material that changes appearance under changing environmental conditions and is configured to improve a contrast of an image projected onto the screen in a presence of ambient light; and
a viewing surface layer adhered to the intermediate layer, wherein the viewing surface lever is formed from one of a transparent and a translucent material, and wherein the viewing surface layer includes a viewing surface textured such that the viewing surface has a frosted appearance capable of reflecting projected light for front-projection viewing.
9. The display screen of claim 5 , wherein the intermediate layer has a shaded appearance.
10. The display screen of claim 8 , wherein the intermediate layer has a generally black appearance.
11. The display screen of claim 8 , wherein the backing structure includes a sheet of glass.
12. The display screen of claim 8 , wherein the backing structure is transparent.
13. The display screen of claim 8 , wherein the viewing surface layer only partially covers the backing layer.
14. The display screen of claim 8 , wherein the viewing surface layer fully covers the backing layer.
