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

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 switch between a first mode and a second mode, the emissive display comprising:

a first pixel configuration activated in the first mode;

a second pixel configuration activated in the second mode;

wherein the first pixel configuration and the second pixel configuration share a common pixel active in both the first mode and the second mode, wherein the common pixel is selected from the group consisting of a green pixel and a blue pixel; and

wherein, in the first mode, a first pixel is active and a second pixel is inactive, and wherein, in the second mode, the first pixel is inactive and the second pixel is active.

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

15. The emissive display of claim 13, wherein the emissive display is an LCD display.

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

17. The emissive display of claim 13, wherein the emissive display is a quantum dot display.

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

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

20. A method of switching an operating mode of an emissive display, the method comprising:

detecting a first operating mode of the display, wherein the first operating mode is one of a day mode or a night mode;

receiving an indication to switch the operating mode of the emissive display;

switching the operating mode of the emissive display from the first operating mode to a second operating mode;

wherein the first operating mode comprises activating a first pixel and a common pixel, the second operating mode comprises activating a second pixel and the common pixel; and

wherein the first pixel is not active in the second operating mode and the second pixel is not active in the first operating mode, wherein the day mode comprises a red pixel in operation, and wherein the night mode comprises a red-orange pixel in operation.
