Providing optical elements over emissive displays
View Patent ↗A display may be formed of a plurality of abutted tiles, each tile contributing a portion of the overall displayed image. Optical elements may be selectively situated between pixels to improve the optical performance of the display. In some embodiments, these optical elements may facilitate the use of relatively thicker cover glasses over the display tiles.
1. A display comprising:
a display panel including a first display element on said panel; and
a layer mounted on said panel including a central more transparent portion and a peripheral less transparent portion.
2. The display of claim 1 including a pair of abutting display panels, including a gap between said panels, an obscuring region situated over said gap.
3. The display of claim 2 wherein said layer is an integral piece including transparent and non-transparent regions, said non-transparent regions situated over said gap.
4. The display of claim 3 wherein said transparent and non-transparent regions are formed integrally in said layer.
5. The display of claim 4 wherein the sides of said non-transparent regions are made reflective.
6. The display of claim 5 wherein said non-transparent region is relatively rectangular.
7. The display of claim 5 wherein said nontransparent region is triangular.
8. The display of claim 5 wherein said nontransparent region is arranged to avoid obscuring emitted light from said element.
9. The display of claim 2 wherein said layer includes a lens element formed therein.
10. The display of claim 9 wherein a lens element is situated over each of said panels.
11. The display of claim 10 including a shield situated over said interface.
12. The display of claim 11 including a lens having an internal surface which reflects light.
13. The display of claim 1 wherein said shield has openings formed therein to obscure said interface.
14. The display of claim 13 wherein said openings are filled with a black material.
15. The display of claim 13 wherein said openings have light reflective coatings thereon.
16. A method comprising:
abutting first and second display tiles at an interface; and
applying a plate to a display panel to form said tiles, said plate having substantially transparent solid and substantially non-transparent solid regions formed therein, and situation said non-transparent regions over said interface.
17. The method of claim 16 including securing the layer over said first and second display tiles to obscure said interface.
18. The method of claim 16 including forming said non-transparent regions integrally in said plate with said transparent regions.
19. The method of claim 18 including forming reflective surfaces on the sides of said non-transparent regions.
20. The method of claim 16 including forming a plate over said first and second tiles, and forming a rectangular non-transparent region in said plate to obscure said interface.
21. The method of claim 16 including forming a plate over said first and second tiles including a triangular region formed therein, and situating said triangular region over said interface.
