Abstract

A display device is provided. The display device includes a display region which includes a first display region and a second display region, where the first display region includes a plurality of first pixels, and the second display region includes a plurality of second pixels and at least one light transmission region, where the light transmission region has light transmittance that is higher than light transmittance of the first pixel and light transmittance of the second pixel, and the second display region has light transmittance that is higher than light transmittance of the first display region.

First claim

What is claimed is:

1. A display device comprising a display region that comprises a first display region and a second display region,
wherein the first display region comprises a plurality of first pixels, and the second display region comprises a plurality of second pixels and at least one light transmission region,
wherein light transmittance of the at least one light transmission region is higher than light transmittance of each of the first pixels and light transmittance of each of the second pixels, and light transmittance of the second display region is higher than light transmittance of the first display region.

2. The display device of claim 1 , wherein a resolution of the second display region is lower than a resolution of the first display region.

3. The display device of claim 2 , wherein the first pixels and the second pixels of the same color have the same size.

4. The display device of claim 1 , wherein the first pixels are larger than the second pixels of the same color.

5. The display device of claim 4 , wherein a resolution of the second display region is the same as a resolution of the first display region.

6. The display device of claim 1 , wherein the at least one light transmission region comprises a plurality of light transmission regions, and wherein the plurality of light transmission regions and the plurality of second pixels are alternately arranged.

7. The display device of claim 1 , further comprising a substrate over the first display region and the second display region.

8. The display device of claim 7 , wherein the substrate overlaps the at least one light transmission region.

9. The display device of claim 1 , wherein an area occupied by the at least one light transmission region is 50% or more of the second display region.

10. The display device of claim 1 , further comprising a light sensing member arranged to overlap the second display region.

11. The display device of claim 10 , wherein the light sensing member comprises at least one of a camera, an infrared proximity sensor, an iris recognition sensor, and a fingerprint sensor comprising a photoelectric conversion element.

12. The display device of claim 11 , wherein the second display region comprises a first second display region and a second second display region spaced apart from the first second display region.

13. The display device of claim 12 , wherein light transmittance of the first second display region is different from light transmittance of the second second display region.

14. The display device of claim 1 , further comprising a non-display region around the display region,
wherein the second display region is in partial contact with the non-display region.

15. The display device of claim 14 , wherein the second display region has an arcuate shape, wherein an internal angle of a figure formed by both ends of an arcuate line and a center of the arcuate shape is in a range of 10° to 180°.

16. The display device of claim 1 , further comprising a signal line crossing the first display region and the second display region,
wherein the signal line comprises a bypass section that bypasses each of the plurality of second pixels in the second display region.

17. The display device of claim 1 , wherein each of the plurality of first pixels and each of the plurality of second pixels comprises an emission region and a non-emission region around the emission region having light transmittance that is lower than the light transmittance of the at least one light transmission region.

18. A display device comprising a display region that comprises a first display region and a second display region,
wherein the first display region comprises a plurality of pixels comprising a plurality of pixel electrodes and a common electrode,
wherein each of the pixel electrodes is on the first display region or the second display region, the common electrode is on an entire surface of the first display region, and the common electrode is located in a partial region of the second display region and defines at least one light transmission opening.

19. The display device of claim 18 , wherein each of the pixel electrodes overlaps the common electrode and does not overlap the at least one light transmission opening.

20. The display device of claim 19 , further comprising an organic layer between the pixel electrodes and the common electrode,
wherein the organic layer is not located in the at least one light transmission opening.

21. The display device of claim 20 , wherein an area of the light transmission opening is 50% or more of the second display region.

22. The display device of claim 18 , wherein light transmittance of the second display region is higher than light transmittance of the first display region.

23. The display device of claim 18 , further comprising a light sensing member to overlap the second display region.

24. The display device of claim 18 , further comprising a substrate over the first display region and the second display region.

25. The display device of claim 24 , wherein the substrate overlaps at least one light transmission region in the second display region.

26. A display device comprising a display region that comprises a first display region and a second display region,
wherein the first display region comprises a plurality of first pixels, and the second display region comprises a plurality of second pixels,
wherein a resolution of the second display region is lower than a resolution of the first display region, and
wherein light transmittance of the second display region is higher than light transmittance of the first display region.

27. The display device of claim 26 , wherein the first display region fully surrounds the second display region.

28. The display device of claim 27 , wherein an area of the first display region is larger than an area of the second display region.
