Abstract

A display device includes a substrate including a first display area, and a second display area surrounding at least a part of the first display area in plan view, a first pixel portion in the first display area, a first pixel circuit portion in the first display area, and electrically connected to the first pixel portion, a circuit-driving portion in the second display area, and configured to drive the first pixel circuit portion, a second pixel portion in the second display area to overlap the circuit-driving portion, a second pixel circuit portion in the second display area, and electrically connected to the second pixel portion, and a light-sensing region in the second display area to overlap an electronic component.

Claims (32)

1 . A display device comprising:

a substrate comprising a first display area, and a second display area surrounding at least a part of the first display area in plan view;

a first pixel portion in the first display area;

a first pixel circuit portion in the first display area, and electrically connected to the first pixel portion;

a circuit-driving portion in the second display area, and configured to drive the first pixel circuit portion;

a second pixel portion in the second display area to overlap the circuit-driving portion;

a second pixel circuit portion in the second display area, and electrically connected to the second pixel portion; and

a light-sensing region in the second display area to overlap an electronic component.

2 . The display device of claim 1 , wherein a distance between adjacent second pixel portions in a first direction is greater than a distance between adjacent first pixel portions in the first direction.

3 . The display device of claim 1 , wherein the light-sensing region is arranged along a periphery of the first display area.

4 . The display device of claim 1 , wherein the first pixel portion comprises a first pixel, a second pixel, and a third pixel that are configured to emit light of respective colors.

5 . The display device of claim 1 , wherein the second pixel portion comprises a first pixel, a second pixel, and a third pixel that are configured to emit light of respective colors.

6 . The display device of claim 4 , wherein a sum of areas of emission areas of the second pixel portion is less than a sum of areas of emission areas of the first pixel portion.

7 . The display device of claim 6 , wherein the sum of the areas of the emission areas of the first pixel portion comprises a sum of areas of emission areas of the first pixel, the second pixel, and the third pixel included in the first pixel portion.

8 . The display device of claim 7 , further comprising:

a pixel-defining layer above the substrate; and

a light-emitting diode comprising a pixel electrode in a first opening defined in the pixel-defining layer, an intermediate layer above the pixel electrode, and a counter electrode,

wherein the first pixel comprises a light-emitting element, and

wherein an area of an emission area of the first pixel is substantially equal to an area of the first opening defined in the pixel-defining layer.

9 . The display device of claim 8 , wherein the electronic component is in a second opening defined in the pixel-defining layer, and

wherein the light-sensing region is substantially equal to an area of the second opening defined in the pixel-defining layer.

10 . The display device of claim 2 , wherein a number of the first pixel portions per unit area of the first display area is substantially equal to a number of the second pixel portions per unit area of the second display area.

11 . The display device of claim 2 , wherein a number of light-sensing regions in the second display area is substantially equal to a number of the second pixel portions in the second display area.

12 . The display device of claim 2 , wherein a number of the second pixel portions per unit area of the second display area is less than a number of the first pixel portions per unit area of the first display area.

13 . The display device of claim 2 , wherein a sum of emission areas of the second pixel portions in the second display area is substantially equal to a sum of emission areas of the first pixel portions in the first display area.

14 . The display device of claim 2 , wherein only the light-sensing region is in the second display area adjacent to sides extending in the first direction of sides of the first display area.

15 . The display device of claim 2 , wherein only the light-sensing region is in the second display area adjacent to sides extending in a second direction crossing the first direction of sides of the first display area.

16 . The display device of claim 1 , wherein the first pixel portion and the first pixel circuit portion overlap each other.

17 . The display device of claim 1 , wherein the second pixel portion and the second pixel circuit portion do not overlap each other.

18 . The display device of claim 2 , wherein the circuit-driving portion comprises a data-driving portion extending in the first direction for providing a data signal to the first and second pixel circuit portions.

19 . The display device of claim 18 , wherein the circuit-driving portion comprises a scan-driving portion extending in a second direction crossing the first direction for providing a scan signal to the first and second pixel circuit portions.

20 . The display device of claim 1 , wherein the electronic component overlapping the light-sensing region comprises a photodetector.
