Abstract

A display apparatus includes a base substrate including an opening area which transmits light, an opening peripheral area which is a non-display area surrounding the opening area, and a display area surrounding the opening peripheral area, a thin film transistor disposed on the base substrate, a light emitting structure electrically connected to the thin film transistor, and a loop-type antenna electrode disposed on the base substrate in the opening peripheral area to surround the opening area.

Claims (35)

1. A display apparatus comprising:

a base substrate including an opening area which transmits light, an opening peripheral area which is a non-display area surrounding the opening area, and a display area surrounding the opening peripheral area;

a thin film transistor disposed on the base substrate;

a light emitting structure electrically connected to the thin film transistor;

a loop-type antenna electrode disposed on the base substrate in the opening peripheral area to surround the opening area; and

a shielding electrode disposed in the opening peripheral area between the base substrate and the loop-type antenna electrode; and

a signal line disposed between the shielding electrode and the base substrate.

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

a thin film encapsulation layer disposed on the light emitting structure,

wherein the loop-type antenna electrode is disposed on the thin film encapsulation layer.

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

a first wiring connected to an end of the loop-type antenna electrode; and

a second wiring connected to an opposite end of the loop-type antenna electrode,

wherein the first wiring and the second wiring extend to a peripheral area, which is a non-display area surrounding the display area, through the display area.

4. The display apparatus of claim 1 , wherein the loop-type antenna electrode includes a transparent conductive material.

5. The display apparatus of claim 1 , wherein a hole or a transparent window is defined or disposed in the opening area of the base substrate.

6. The display apparatus of claim 1 , wherein the loop-type antenna electrode has a C-shape or an O-shape.

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

a cover window disposed on the loop-type antenna electrode,

wherein the loop-type antenna electrode is disposed between the cover window and the base substrate.

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

an optical module disposed to overlap the opening area.

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

a driver including a radio frequency integrated circuit which provides a power to the loop-type antenna electrode.

10. The display apparatus of claim 1 , wherein the light emitting structure includes:

a first electrode electrically connected to the thin film transistor;

a light emitting layer disposed on the first electrode; and

a second electrode disposed on the light emitting layer.

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

another loop-type antenna electrode disposed on the base substrate in the opening peripheral area to surround the opening area,

wherein the another loop-type antenna electrode is spaced apart from the loop-type antenna electrode, and

wherein the loop-type antenna electrode surrounds the another loop-type antenna electrode.

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

a touch electrode disposed on the light emitting structure.

13. The display apparatus of claim 12 , wherein the touch electrode and the loop-type antenna electrode are disposed in a same layer as each other.
