Abstract

A display apparatus may include a first plurality of pixels, a substrate, a first signal line, and a load matching device. The substrate may include a first opening, a first non-display area, and a main display area. The first non-displaying area may at least partially surround the first opening. The main display area may support the first plurality of pixels. The first signal line may be electrically connected to the first plurality of pixels, may overlap the main display area, and may overlap the first non-display area. The load matching device may overlap the first non-display area and may provide a first electrical load to the first signal line.

Claims (20)

1. A display apparatus, comprising:

a plurality of pixels;

a substrate including a first opening, a second opening spaced apart from the first opening, a non-display area surrounding each of the first and second openings, and a main display area in which the pixels are disposed;

a signal line electrically connected to the pixels and overlapping the main display area, the signal line not overlapping the non-display area; and

a load matching device including a load matching electrode disposed near the first and second openings in the non-display area.

2. The display apparatus of claim 1 , further comprising:

a cover window disposed on the substrate to cover the first opening, the second opening, the non-display area, and the main display area.

3. The display apparatus of claim 2 , wherein a light blocking member is disposed between the substrate and the cover window in the non-display area to overlap the non-display area.

4. The display apparatus of claim 2 , wherein an overcoat layer is disposed between the substrate and the cover window in the non-display area to compensate for an overall height of the display apparatus.

5. The display apparatus of claim 1 , wherein a light emitting structure is cut in the non-display area by a groove or a partition.

6. The display apparatus of claim 5 , wherein the groove is formed on the substrate in the non-display area to surround at least one of the first and second openings.

7. The display apparatus of claim 5 , wherein the partition wall is formed on the substrate in the non-display area to surround at least one of the first and second openings.

8. The display apparatus of claim 1 , wherein a size of the first opening is equal to a size of the second opening.

9. The display apparatus of claim 1 , wherein a size of the first opening is different from a size of the second opening.

10. The display apparatus of claim 1 , wherein the first opening includes a first through hole that extends through the substrate.

11. The display apparatus of claim 10 , wherein a first optical module is disposed to overlapping a position of the first opening.

12. The display apparatus of claim 10 , wherein the second opening includes a second through hole that extends through the substrate.

13. The display apparatus of claim 12 , wherein a second optical module is disposed to overlapping a position of the second opening.

14. The display apparatus of claim 1 , wherein the signal line is a scan line for providing a scan signal to the pixels.

15. The display apparatus of claim 1 , wherein the load matching device comprises a zigzag structure electrically connected to the signal line.
