Abstract

A display device includes a display panel including a first region and a second region, and a sensing module on a rear side of the display panel. The first region includes a first pixel area to display an image. The second region includes a second pixel area to display the image and a transmission area to transmit light output by the sensing module. The second region overlaps the sensing module. The second pixel area overlaps a first layer that blocks light output by the sensing module. The transmission area does not overlap the first layer.

Claims (56)

1. A display device, comprising:

a display panel including a first region and a second region; and

a sensing module on a rear side of the display panel, wherein

the first region includes a first pixel area to display an image,

the second region overlaps the sensing module and the first region does not overlap the sensing module,

the second pixel area overlaps a first layer that blocks output by the sensing module, and

the transmission area does not overlap the first layer, and

the first region does not overlap the first layer.

2. The display device as claimed in claim 1 , wherein:

the second pixel area includes a plurality of transistors, and

the first layer overlaps all of the plurality of transistors.

3. The display device as claimed in claim 1 , wherein:

the second pixel area includes a plurality of transistors, and

the first layer overlaps some of the plurality of transistors.

4. The display device as claimed in claim 1 , wherein the transmission area is separated from the first layer in a plan view.

5. The display device as claimed in claim 1 , wherein the first pixel area is separated from the first layer in a plan view.

6. The display device as claimed in claim 1 , wherein:

the first pixel area includes a plurality of transistors.

7. The display device as claimed in claim 1 , wherein:

the second pixel area includes a plurality of transistors, and

the first layer overlaps at least one of the plurality of transistors.

8. The display device as claimed in claim 1 , wherein the first pixel area does not overlap the first layer.

9. A display device, comprising:

a display panel including a first region and a second region; and

a sensing module on a rear side of the display panel, wherein

the first region includes a first pixel area to display an image,

the second region includes a second pixel area to display the image and a transmission area to transmit light output by the sensing module,

the second region overlaps the sensing module,

the second pixel area overlaps a first layer that blocks an output by the sensing module,

the second pixel area includes a plurality of transistors,

the first layer overlaps at least one of the plurality of transistors,

the first pixel area includes the first layer overlapping some of the plurality of transistors, and

the second pixel area overlaps more of the first layer than the first pixel area.

10. The display device as claimed in claim 1 , wherein an area occupied by the transmission area is 20% to 90% of the second region.

11. The display device as claimed in claim 1 , wherein:

the display panel includes a first substrate on which a transistor is provided, and

the first layer is between the sensing module and the transistor.

12. A display device, comprising:

overlap percentages of the first layer in the first pixel area and in the second pixel area are different with respect to individual pixel areas, and

the first region does not overlap the first layer.

13. The display device as claimed in claim 12 , wherein the transmission area does not overlap the first layer.

14. The display device as claimed in claim 12 , wherein the transmission area does not include a transistor.

15. The display device as claimed in claim 12 , wherein:

the first pixel area does not overlap the first layer, and

at least part of the second pixel area overlaps the first layer.
