Display device and electronic apparatus

1. A display device, comprising:

a display part having a first display region and a second display region, wherein the first display region is around the second display region, a pixel density of the second display region is less than a pixel density of the first display region, a plurality of first sub-pixels within the first display region are configured into a red-green-blue-green array, a plurality of second sub-pixels within the second display region are configured into a red-green-blue array, a thickness of each of the second sub-pixels within the second display region is greater than a thickness of each of the first sub-pixels within the first display region, and a gap between the second sub-pixels of two adjacent rows or two adjacent columns within the second display region is larger than a gap between the first sub-pixels of two adjacent rows or two adjacent columns within the first display region; and

a camera part disposed at a position corresponding to the second display region on a side of the display part, wherein the camera part has an image-acquiring-end portion toward the display part;

wherein the display part comprises a substrate, an array layer, a pixel layer, a thin-film encapsulation layer, and a cover, which are sequentially stacked, and the substrate is provided with a concave-hole portion having a convex curved surface combined with the image-acquiring-end portion having a concave curved surface.

2. The display device as claimed in claim 1 , wherein a light-emitting area of each of the second sub-pixels within the second display region is greater than a light-emitting area of each of the first sub-pixels within the first display region.

3. The display device as claimed in claim 1 , wherein the substrate comprises a first polyimide layer, a silicon oxide layer, and a second polyimide layer, wherein the silicon oxide layer is located between the first polyimide layer and the second polyimide layer, the second polyimide layer is combined with the array layer, a part of the concave-hole portion is formed into a closed-hole portion on the second polyimide layer, and the closed-hole portion is attached to the image-acquiring-end portion.

4. The display device as claimed in claim 1 , wherein the display part is electrically connected to a controller that generates a first gamma control signal and a second gamma control signal, wherein the first gamma control signal is configured to control the first sub-pixels within the first display region, the second gamma control signal is configured to control the second sub-pixels within the second display region, so that a brightness curve of the second display region is raised to a brightness curve of the first display region.

5. The display device as claimed in claim 1 , wherein the second display region is shaped as a rectangular region or a hexagonal region.

6. A display device, comprising:

a display part having a first display region and a second display region, wherein the first display region is around the second display region, a pixel density of the second display region is less than a pixel density of the first display region, a plurality of first sub-pixels within the first display region are configured into a red-green-blue-green array, and a plurality of second sub-pixels within the second display region are configured into a red-green-blue array; and

a camera part disposed at a position corresponding to the second display region on a side of the display part, wherein the camera part has an image-acquiring-end portion toward the display part;

wherein the display part comprises a substrate, an array layer, a pixel layer, a thin-film encapsulation layer, and a cover, which are sequentially stacked, and the substrate is provided with a concave-hole portion having a convex curved surface combined with the image-acquiring-end portion having a concave curved surface.

7. The display device as claimed in claim 6 , wherein a light-emitting area of each of the second sub-pixels within the second display region is greater than a light-emitting area of each of the first sub-pixels within the first display region.

8. The display device as claimed in claim 6 , wherein a thickness of each of the second sub-pixels within the second display region is greater than a thickness of each of the first sub-pixels within the first display region.

9. The display device as claimed in claim 6 , wherein a gap between the second sub-pixels of two adjacent rows or two adjacent columns within the second display region is larger than a gap between the first sub-pixels of two adjacent rows or two adjacent columns within the first display region.

10. The display device as claimed in claim 6 , wherein the substrate comprises a first polyimide layer, a silicon oxide layer, and a second polyimide layer, wherein the silicon oxide layer is located between the first polyimide layer and the second polyimide layer, the second polyimide layer is combined with the array layer, a part of the concave-hole portion is formed into a closed-hole portion on the second polyimide layer, and the closed-hole portion is attached to the image-acquiring-end portion.

11. The display device as claimed in claim 6 , wherein the display part is electrically connected to a controller that generates a first gamma control signal and a second gamma control signal, wherein the first gamma control signal is configured to control the first sub-pixels within the first display region, the second gamma control signal is configured to control the second sub-pixels within the second display region, so that a brightness curve of the second display region is raised to a brightness curve of the first display region.

12. The display device as claimed in claim 6 , wherein the second display region is shaped as a rectangular region or a hexagonal region.

13. An electronic apparatus comprising the display device as claimed in claim 6 .
