Abstract

The disclosure relates to an emissive display configured to operate in a day mode and a night mode. The emissive display comprises a day pixel configured to operate in the day mode. The emissive display also comprises a night pixel configured to operate in the night mode, wherein the night pixel is not operational in the day mode. The emissive display also comprises a common pixel configured to operate in both the day mode and the night mode. The emissive display also comprises a detector configured to selectively change an operating mode of the display between the day mode and the night mode based on a detected indication.

Claims

1. An emissive display configured to operate in a day mode and a night mode, the display comprising:

a day pixel configured to operate in the day mode;

a night pixel configured to operate in the night mode, wherein the night pixel is not operational in the day mode;

a common pixel configured to operate in both the day mode and the night mode; and

a detector configured to selectively change an operating mode of the emissive display between the day mode and the night mode based on a detected indication;

wherein the common pixel is selected from the group consisting of a green pixel and a blue pixel.

2. The emissive display of claim 1, wherein the display is an electroluminescent display.

3. The emissive display of claim 1, wherein the display comprises an OLED display.

4. The emissive display of claim 1, wherein the display comprises an LCD display.

5. The emissive display of claim 1, wherein the display comprises an quantum dot display.

6. The emissive display of claim 1, wherein the display comprises a LED display.

7. The emissive display of claim 1, wherein the display comprises a micro-LED display.

8. The emissive display of claim 1, wherein the detected indication comprises a communication from a remote processor.

9. The emissive display of claim 1, wherein the detected indication comprises a detected ambient light condition.

10. The emissive display of claim 1, wherein the detected indication comprises a detected user input.

11. The emissive display of claim 1, wherein the night pixel comprises a red-orange pixel.

12. The emissive display of claim 1, wherein the day pixel comprises a red pixel.

13. An emissive display configured to operate in a day mode and a night mode, the display comprising:

a day pixel configured to operate in the day mode;

a night pixel configured to operate in the night mode, wherein the night pixel is not operational in the day mode;

a common pixel configured to operate in both the day mode and the night mode; and

a detector configured to selectively change an operating mode of the emissive display between the day mode and the night mode based on a detected indication;

wherein the night pixel comprises a red-orange pixel.

14. The emissive display of claim 13, wherein the display is an electroluminescent display.

15. The emissive display of claim 13, wherein the display comprises an OLED display.

16. The emissive display of claim 13, wherein the display comprises an LCD display.

17. The emissive display of claim 13, wherein the display comprises an quantum dot display.

18. The emissive display of claim 13, wherein the display comprises a LED display.

19. The emissive display of claim 13, wherein the display comprises a micro-LED display.

20. The emissive display of claim 13, wherein the detected indication comprises a communication from a remote processor.

21. The emissive display of claim 13, wherein the detected indication comprises a detected ambient light condition.

22. The emissive display of claim 13, wherein the detected indication comprises a detected user input.

23. The emissive display of claim 13, wherein the day pixel comprises a red pixel.
