Abstract

Methods, systems, and apparatus, including computer programs encoded on computer storage media, for changing a distributed mode loudspeaker's fundamental frequency. One of the systems may include a light emitting diode display that includes an array of pixels, each pixel including, for each color of multiple colors, a directional light emitter and a wide-angle light emitter, a first combination of all the directional light emitters configured to generate a first display image viewable within a first viewing angle, and a second combination of all the wide-angle light emitters configured to generate a second display image concurrently with the generation of the first display image that is viewable within a second viewing angle. The first display image is a different image than the second display image and the first viewing angle is a narrower viewing angle than, and included within, the second viewing angle.

First claim

What is claimed is:

1. A light emitting diode display comprising:
an array of pixels, each pixel comprising, for each color of multiple colors, a directional light emitter and a wide-angle light emitter,
a first combination of all the directional light emitters configured to generate a first display image viewable within a first viewing angle, and
a second combination of all the wide-angle light emitters configured to generate, concurrently with the generation of the first display image, a second display image that a) is a different image than the first display image, b) is viewable within a second viewing angle that is wider than and encompasses the first viewing angle, and c) creates, within the first viewing angle, an overlaid image from the combination of the first display image and the second display image.

2. The light emitting diode display of claim 1 , wherein the array of pixels comprises groups of color specific sub-pixels, each of the color specific sub-pixels comprising a directional light emitter and a wide-angle light emitter.

3. The light emitting diode display of claim 1 , wherein the array of pixels comprises groups of viewing angle specific sub-pixels, each of the viewing angle specific sub-pixels comprising, for each color in a group of colors, a light emitter specific to the corresponding viewing angle and for the respective color.

4. The light emitting diode display of claim 3 , wherein the group of colors consists substantially of red, green, and blue.

5. The light emitting diode display of claim 3 , wherein the group of colors consists substantially of cyan, magenta, yellow, and black.

6. The light emitting diode display of claim 1 , wherein each of the directional light emitters is adjacent to another directional light emitter of a different color.

7. The light emitting diode display of claim 6 , comprising:
a directional pixel-subset that comprises, for each color in a group of colors, a respective directional light emitter; and
a wide-angle pixel-subset that comprises, for each color in the group of colors, a respective wide-angle light emitter, each directional pixel-subset included in the light emitting diode display adjacent to a corresponding wide-angle pixel-subset that has the same position in the array of pixels as the directional pixel-subset.

8. The light emitting diode display of claim 1 , wherein each of the directional light emitters is adjacent to a wide-angle light emitter of the same color.

9. The light emitting diode display of claim 1 , comprising an electronic controller to generate a signal that causes the light emitting diode display to change a viewing angle for the directional light emitters.

10. The light emitting diode display of claim 9 , wherein the electronic controller comprises an array of controllable light directing elements.

11. The light emitting diode display of claim 10 , wherein the electronic controller comprises one light directing element for each of the directional light emitters.

12. The light emitting diode display of claim 10 , wherein the electronic controller comprises one light directing element for each group of the directional light emitters.

13. The light emitting diode display of claim 9 , comprising a communication module to receive viewing angle adjustment data and provide the viewing angle adjustment data to the electronic controller.

14. The light emitting diode display of claim 9 , comprising an eye-tracking component to determine eye movement data for a viewer, generate viewing angle adjustment data, and provide the viewing angle adjustment data to the electronic controller to change the viewing angle of the directional light emitters.

15. A method comprising:
generating, by a light emitting diode display using a plurality of wide-angle emitters, a first display image viewable in a first viewing angle; and
generating, by the display using a plurality of directional emitters concurrently with generation of the first display image, a second display image that a) is a different image than the first display image, b) is viewable within a second viewing angle that is wider than and encompasses the first viewing angle, and c) creates, within the first viewing angle, an overlaid image from the combination of the first display image and the second display image.

16. The method of claim 15 , wherein generating, by the display using the plurality of directional emitters concurrently with generation of the first display image, the second display image comprises
generating, by the display using the plurality of directional emitters after generation of the first display image, the second display image for presentation concurrently with presentation of the first display image.

17. The method of claim 15 , comprising:
changing, by the display using an electronic controller, the second viewing angle of the second display image.

18. The method of claim 17 , wherein changing the second viewing angle of the second display image comprising adjusting, by the electronic controller, one or more light directing elements to change the second viewing angle of the second display image.

19. The method of claim 17 , comprising:
receiving viewing angle adjustment data; and
generating, by the electronic controller, angle adjustment commands using the viewing angle adjustment data, wherein changing, by the electronic controller, the second viewing angle of the second display image comprises adjusting, by the electronic controller, one or more light directing elements using the angle adjustment commands.

20. The method of claim 19 , wherein receiving the viewing angle adjustment data comprising:
capturing, by a camera, one or more images; and
determining, by an eye-tracking module, the viewing angle adjustment data using the one or more images.
