Abstract

A display panel includes: a substrate including a main display area, a first component area, a second component area, and a peripheral area; a first subpixel on the main display area, and a first pixel circuit connected to the first subpixel; a second subpixel on the first component area; a second pixel circuit spaced apart from the second subpixel; and a connection wiring connecting the second subpixel to the second pixel circuit.

First claim

What is claimed is:

1. A display panel comprising:
a substrate comprising a main display area, a first component area, a second component area, and a peripheral area;
a first subpixel on the main display area, and a first pixel circuit connected to the first subpixel;
a second subpixel on the first component area;
a second pixel circuit spaced apart from the second subpixel; and
a connection wiring connecting the second subpixel to the second pixel circuit,
wherein the second pixel circuit is between the first component area and the second component area.

2. The display panel of claim 1 , wherein the second pixel circuit is in the peripheral area.

3. The display panel of claim 1 , wherein the connection wiring comprises a transparent conductive material.

4. The display panel of claim 3 , further comprising an additional connection wiring connecting the connection wiring to the second pixel circuit, wherein the additional connection wiring includes a material different from a material of the connection wiring.

5. The display panel of claim 1 , wherein the first subpixel and the second subpixel are configured to emit a same color of light, and
a size of the second subpixel is greater than a size of the first subpixel.

6. A display panel comprising:
a substrate comprising a main display area, a first component area, a second component area, and a peripheral area;
a first subpixel on the main display area, and a first pixel circuit connected to the first subpixel;
a second subpixel on the first component area;
a second pixel circuit spaced apart from the second subpixel;
a connection wiring connecting the second subpixel to the second pixel circuit; and
a third subpixel between the first component area and the second component area.

7. The display panel of claim 6 , wherein
the third subpixel is connected to a third pixel circuit in the peripheral area.

8. The display panel of claim 1 , further comprising:
a main scan line extending in a first direction, and
a scan connection line connected to the main scan line.

9. The display panel of claim 8 , wherein the scan connection line surrounds one side of the first component area.

10. The display panel of claim 8 , wherein the scan connection line is in the peripheral area.

11. The display panel of claim 1 , wherein the first subpixel comprises a first pixel electrode and a first emission layer, and the second subpixel comprises a second pixel electrode and a second emission layer.

12. The display panel of claim 11 , further comprising:
an opposite electrode on each of the first emission layer and the second emission layer; and
an upper layer on the opposite electrode,
wherein an end of the opposite electrode and an end of the upper layer coincide with each other.

13. The display panel of claim 11 , wherein the first pixel electrode or the second pixel electrode and the connection wiring are formed by a same process.

14. The display panel of claim 1 , further comprising a bottom metal layer on the first component area.

15. The display panel of claim 14 , further comprising a dummy subpixel is the peripheral area or the first component area and the second component area.

16. The display panel of claim 1 , wherein the substrate further comprises a third component area.

17. A display apparatus comprising:
a display panel comprising a substrate, the substrate comprising a main display area, a first component area, a second component area, and a peripheral area;
a first component below the display panel corresponding to the first component area; and
a second component below the display panel corresponding to the second component area,
wherein the display panel comprises:
a first subpixel on the main display area, and a first pixel circuit connected to the first subpixel;
a second subpixel on the first component area;
a second pixel circuit spaced apart from the second subpixel; and
a connection wiring connecting the second subpixel to the second pixel circuit,
wherein the second pixel circuit is between the first component area and the second component area.

18. The display apparatus of claim 17 , wherein the first component and the second component each comprise at least one of a proximity sensor, an illuminance sensor, an RGB sensor, an infrared sensor, a fingerprint recognition sensor, an ultrasonic sensor, an optical sensor, a microphone, an environmental sensor, a chemical sensor, or a radar sensor.

19. The display apparatus of claim 18 , wherein the substrate further comprises a third component area, and the display apparatus further comprises a third component corresponding to the third component area.
