Abstract

A display including a screen layer for displaying a unified image to a viewer on a viewing side of the screen layer that is opposite a backside of the screen layer, and an illumination layer having an array of light sources. Each light source in the array is configured to emit a divergent projection beam having a limited angular spread. A display layer is disposed between the screen layer and the illumination layer, and includes a matrix of pixlets, a spacing region disposed between the pixlets in the matrix, wherein the array of light sources are positioned to emit the divergent projection beams having limited angular spread to project sub-images displayed by the pixlets as magnified sub-images on the backside of the screen layer, the magnified sub-images to combine to form a substantially seamless unified image, and one or more components positioned on the display layer in the spacing region.

First claim

The invention claimed is:

1. A display apparatus comprising:
a screen layer for displaying a unified image to a viewer on a viewing side of the screen layer that is opposite a backside of the screen layer;
an illumination layer having an array of light sources, wherein each light source in the array is configured to emit a divergent projection beam having a limited angular spread; and
a display layer disposed between the screen layer and the illumination layer, the display layer comprising:
a matrix of pixlets;
a spacing region disposed between the pixlets in the matrix; wherein the array of light sources is positioned to emit the divergent projection beams having limited angular spread to project sub-images displayed by the pixlets as magnified sub-images on the backside of the screen layer, the magnified sub-images to combine to form the unified image that is substantially seamless, and
one or more components positioned on the display layer in the spacing region, wherein the one or more components includes a single electronic component having a cross shape that is mounted in both a vertically-extending portion and a horizontally-extending portion of the spacing region between adjacent pixlets.

2. The display apparatus of claim 1 wherein the pixlets are offset from the light sources in the array of light sources by a second fixed distance.

3. The display apparatus of claim 1 wherein an internal spacing between each adjacent pixlet in the matrix is a first dimension and wherein an external spacing between edges of the display layer and edges of the pixlets is a second dimension that is half of the first dimension.

4. The display apparatus of claim 1 wherein the one or more components are positioned on one side of the display layer or wherein the one or more components are positioned on both sides of the display layer.

5. The display apparatus of claim 1 wherein the one or more components are positioned in a part of the spacing region between adjacent pixlets.

6. The display apparatus of claim 1 wherein the one or more components are positioned in a part of the spacing region between diagonally opposed pixlets.

7. The display apparatus of claim 1 wherein the one or more components include electronic components that support the pixlets.

8. The display apparatus of claim 7 wherein the electronic components can include driver circuitry and/or memory.

9. The display apparatus of claim 1 wherein the one or more components can include sensors or transducers.

10. The display apparatus of claim 9 wherein the sensors can include electronic sensors, optical sensors, infrared sensors, cameras, eye-tracking cameras, or touch sensors.

11. The display apparatus of claim 9 wherein the transducers can include microphones, speakers, antennas, or solar panels.

12. A multi-panel display comprising:
a plurality of tileable displays arranged to form the multi-panel display, each tileable display comprising:
a screen layer for displaying a unified image to a viewer on a viewing side of the screen layer that is opposite a backside of the screen layer;
an illumination layer having an array of light sources, wherein each light source in the array is configured to emit a divergent projection beam having a limited angular spread; and
a display layer disposed between the screen layer and the illumination layer, the display layer comprising:
a matrix of pixlets;
a spacing region disposed between the pixlets in the matrix;
wherein the array of light sources are positioned to emit the divergent projection beams having limited angular spread to project sub-images displayed by the pixlets as magnified sub-images on the backside of the screen layer, the magnified sub-images to combine to form the unified image that is substantially seamless, and
wherein the unified images from each tileable display combine to form an overall image displayed by the multi-panel display; and
one or more components positioned on the display layer in the spacing region, wherein the one or more components includes a single electronic component having a cross shape that is mounted in both a vertically-extending position and a horizontally-extending position of the spacing region between adjacent pixlets.

13. The multi-panel display of claim 12 wherein the one or more components are positioned on one side of the display layer or wherein the one or more components are positioned on both sides of the display layer.

14. The multi-panel display of claim 12 wherein the one or more components are positioned in a part of the spacing region between adjacent pixlets.

15. The multi-panel display of claim 12 wherein the one or more components are positioned in a part of the spacing region between diagonally opposed pixlets.

16. The multi-panel display of claim 12 wherein the one or more components include electronic components that support the pixlets.

17. The multi-panel display of claim 16 wherein the electronic components can include driver circuitry and/or memory.

18. The multi-panel display of claim 12 wherein the one or more components can include sensors or transducers.

19. The multi-panel display of claim 18 wherein the sensors can include electronic sensors, optical sensors, infrared sensors, cameras, eye-tracking cameras, or touch sensors.

20. The multi-panel display of claim 18 wherein the transducers can include microphones, speakers, antennas, or solar panels.
