Tiled displays using multiple display panels over monolithic backlight modules

1. A modular display comprising:

a monolithic backlight module to generate light;

a plurality of display panels disposed over the monolithic backlight module, and tiled such that each display panel abuts another display panel along at least one edge thereof to form a seam, each display panel including:

a light modulation layer disposed adjacent to the monolithic backlight module to modulate the lamp light received from a first side and to output a display image from a second side; and

seam-concealing optics disposed over the second side of the light modulation layer.

2. The modular display of claim 1 wherein the seam-concealing optics comprise an optical expansion layer disposed over the second side of the light modulation layer to expand the display image to an area larger than the light modulation layer to conceal bezel seams between light modulation layers of adjacent display panels.

3. The modular display of claim 1 wherein at least one of the plurality of display panels includes a non-linear edge that mates with a corresponding non-linear edges of an adjacent display panel.

4. The modular display of claim 1 wherein the plurality of tiled display panels matched the monolithic backlight module in size, shape, or both size and shape.

5. The modular display of claim 1 wherein each of the plurality of display panels has the same shape.

6. The modular display of claim 1 wherein each of the plurality of display panels has a polygonal shape.

7. The modular display of claim 1 wherein the monolithic backlight module comprises a plurality of light sources pointed toward the plurality of display panels.

8. The modular display of claim 7 wherein the spacing between light sources decreases near a seam.

9. The modular display of claim 1 wherein the monolithic backlight module comprises:

a plurality of light sources positioned along at least one edge of the backlight module; and

an optical structure within the backlight module to redirect light from the plurality of light sources toward the plurality of display panels.

10. The modular display of claim 1 wherein the monolithic backlight module comprises:

collimating optics to direct collimated light toward the plurality of display panels; and

a plurality of high-intensity light sources optically coupled to the collimating optics.

11. The modular display of claim 1 wherein the size of the monolithic backlight panel exceeds the size of the tiled display panels.

12. The modular display of claim 1 wherein the monolithic backlight panel has a polygonal shape.

13. A process for forming a modular display, the process comprising:

providing a monolithic backlight module to generate light;

tiling a plurality of display panels over the monolithic backlight module, such that each display panel abuts another display panel along at least one edge thereof to form a seam, each display panel including:

a light modulation layer disposed adjacent to the monolithic backlight module to modulate the lamp light received from a first side and to output a display image from a second side; and

seam-concealing optics disposed over the second side of the light modulation layer.

14. The process of claim 13 wherein the seam-concealing optics comprise an optical expansion layer disposed over the second side of the light modulation layer to expand the display image to an area larger than the light modulation layer to conceal bezel seams between light modulation layers of adjacent display panels.

15. The process of claim 13 wherein at least one of the plurality of display panels includes a non-linear edge that mates with a corresponding non-linear edges of an adjacent display panel.

16. The process of claim 13 wherein the monolithic backlight module comprises a plurality of light sources pointed toward the plurality of display panels.

17. The process of claim 16 , further comprising decreasing the spacing between light sources decreases a seam.

18. The process of claim 13 wherein the monolithic backlight module comprises:

a plurality of light sources positioned along at least one edge of the backlight module; and

an optical structure within the backlight module to redirect light from the plurality of light sources toward the plurality of display panels.

19. The process of claim 13 wherein the monolithic backlight module comprises:

collimating optics to direct collimated light toward the plurality of display panels; and

a plurality of high-intensity light sources optically coupled to the collimating optics.
