Abstract

A multi-layer display screen capable of being tiled without a visible gap between tiled screens and methods of using said device are described herein. In one embodiment, a system includes a light generator configured to produce light and a multi-layer screen with a plurality of layers. The multi-layer screen can be configured to permit the light from the light generator to propagate therethrough. The plurality of layers can include an opaque region layer having a plurality of opaque regions and a first layer comprising one or more abutted layers disposed within a common plane, the abutted layers spaced apart by a gap, wherein the gap is coincident with the opaque region.

Claims (40)

1. A system comprising:

a light generator configured to produce light; and

a multi-layer screen, the multi-layer screen configured to permit the light from the light generator to propagate therethrough, the plurality of layers comprising:

a first light propagation layer having a plurality of first light propagation regions and a plurality of second light propagation regions;

a second layer comprising one or more abutted layers disposed within a common plane, wherein the abutted edges of each of the abutted layers are spaced apart by a first gap, wherein the first gap is coincident with a first layer first light propagation region

a third layer, the third layer comprising one or more abutted layers disposed within a common plane, the abutted layers spaced apart by a second gap wherein the first gap and the second gap are positioned along a bisecting line of one of the first light propagation regions wherein the first gap and the second gap are positioned along distinct bisecting lines.

2. The system of claim 1 , wherein the second gap is coincident with a second light propagation region.

3. The system of claim 1 , wherein the first gap and the second gap are positioned along a common bisecting line.

4. The system of claim 1 , wherein the light generator is further configured to boost the light of the second light propagation region around the area of the first gap.

5. The system of claim 1 , wherein the first light propagation regions are opaque.

6. The system of claim 1 , wherein the multi-layer screen is configured such that light produced by the light generator is not propagated through the first light propagation regions.

7. The system of claim 1 , wherein the first light propagation regions are configured such that less light is received or propagated by the first light propagation regions than the second light propagation regions.

8. The system of claim 1 , wherein the multi-layer screen is configured such that light produced by the light generator is propagated through the second light propagation regions.

9. The system of claim 1 , wherein the second light propagation regions are configured to provide lambertian emission.

10. The system of claim 1 , wherein at least two of the plurality of multi-layer screens are connected using a transparent tape, where the edges of the transparent tape are coincident with a first light propagation region.

11. The system of claim 1 , further comprising a polarizing layer, wherein the edges of the polarizing layer are coincident with a first light propagation region.

12. The system of claim 11 , wherein the polarization layer comprises a polarizer and a film patterned retarder.

13. A system comprising:

a light generator configured to produce and direct light; and

a plurality of multi-layer screens, each multi-layer screen comprising:

a servo layer configured to provide feedback and having a first edge;

a second layer configured to deliver visible light to a viewer, configured to have two or more opaque light propagation regions and having a second edge;

a filter layer configured to filter a wavelength of light received from at least the light generator and having a third edge, wherein the first edge and the second edge are not coinciding with the third edge; and

the plurality of multi-layer screens being configured to connect between at least the first edge, the second edge and the third edge of the corresponding screen to create a first gap, a second gap and a third gap respectively, wherein at least one of the first gap, the second gap and the third gap are configured adjacent to one or more opaque light propagation regions wherein the first gap is positioned along a first bisecting line of a first opaque light propagation region and the second gap is positioned along a second bisecting line of a second opaque light propagation region.

14. The system of claim 13 , wherein the second layer comprises:

one or more phosphor stripes configured to receive light from the light generator and produce one or more wavelengths of light in response to the light received; and

one or more segments positioned between and in parallel with the phosphor stripes, the segments configured to separate the phosphor stripes from one another.

15. The system of claim 13 , wherein at least two of the plurality of multi-layer screens are connected between a first distinct layer and a second distinct layer at the same plane, the first distinct layer and the second distinct layer being abutted to one another, wherein the first distinct layer and the second distinct layer are connected using a third layer, the third layer being layer adjacent to the first distinct layer and second distinct layer.

16. The system of claim 15 , wherein the first distinct layer and the second distinct layer are configured to overlap an opaque light propagation region of the second layer.

17. The system of claim 13 , wherein the filter layer is a polarizing layer.

18. A system comprising:

a light generator configured to produce a scanning light; and

a multi-layer screen with a plurality of layers, the multi-layer screen configured to permit the light from the light generator to propagate therethrough, the plurality of layers comprising:

a first light propagation layer having a plurality of first light propagation regions and a plurality of second light propagation regions; and

a second layer comprising two or more abutted layers disposed within a common plane, comprising:

a first layer comprising a first abutted edge and a second layer comprising a second abutted edge, the first abutted edge and the second abutted edge having a common plane and spaced apart by a first gap, wherein the first gap is coincident with the first light propagation region of the first light propagation layer; and

the second layer comprising a third abutted edge and a third layer comprising a fourth abutted edge, the third abutted edge and the fourth abutted edge having a common plane and spaced apart by a second gap, wherein the second gap is coincident with a scan line, and wherein at least one layer is scanned by a nearly fixed aperture sized beam of light along the scan line wherein the first gap and the second gap are positioned along a bisecting line of one of the first light propagation regions wherein the first gap and the second gap are positioned along distinct bisecting lines.

19. The system of claim 18 , the light generator is further configured to render image information in producing the scan line in line with the second gap.

20. The system of claim 18 , the light generator is further configured to render image information in producing the scan line not in line with the second gap.

21. The system of claim 18 , wherein the first light propagation region is opaque.
