Abstract

A display apparatus includes a display panel which have first display pads arranged in a first direction, a main circuit board, a first flexible circuit board which includes first substrate pads connected to the main circuit board and the first display pads and a first driving chip connected to the first substrate pads, and is bent in a direction toward a back surface of the display panel, and a protective member disposed on the first flexible circuit board. The protective member covers the first driving chip.

Claims (63)

1. A display apparatus comprising:

a protective member disposed on the first flexible circuit board, wherein the protective member comprises a first extension pattern and a second extension pattern which are spaced apart from each other along the first direction and extended along a second direction crossing the first direction, and a connection pattern which connects the first extension pattern and the second extension pattern and is extended along the first direction,

wherein the connection pattern covers the first driving chip.

2. The display apparatus of claim 1 , wherein the first flexible circuit board comprises a lower surface from which the first substrate pads are exposed and an upper surface facing the lower surface,

wherein the lower surface faces the back surface of the display panel when the first flexible circuit board is bent.

3. The display apparatus of claim 2 , wherein:

the first driving chip is mounted on the lower surface; and

the protective member covers the first driving chip and a portion of the lower surface.

4. The display apparatus of claim 2 , wherein:

the first driving chip is mounted on the upper surface; and

the protective member covers the first driving chip and a portion of the upper surface.

5. The display apparatus of claim 1 , wherein the first flexible circuit board further comprises:

a first portion which overlaps at least a portion of the main circuit board;

a second portion which overlaps at least a portion of the display panel; and

a third portion which connects the first portion and the second portion,

wherein when the first flexible circuit board is bent, the third portion has a relatively greater curvature than each of the first portion and the second portion.

6. The display apparatus of claim 5 , wherein the first driving chip is disposed on the first portion, and the protective member covers the first driving chip.

7. The display apparatus of claim 5 , wherein:

the first driving chip is disposed on the third portion; and

the protective member covers the first driving chip.

8. The display apparatus of claim 1 , wherein:

the display panel further comprises second display pads disposed spaced apart from the first display pads in a second direction crossing the first direction and arranged in the first direction; and

the display apparatus further comprises a second flexible circuit board which includes second substrate pads connected to the main circuit board and the second display pads and a second driving chip connected to the second substrate pads, and is bent in the direction toward the back surface of the display panel,

wherein a portion of the second flexible circuit board covers a portion of the first flexible circuit board.

9. The display apparatus of claim 8 , wherein the protective member is provided in plurality, and one of the protective members covers the second driving chip.

10. The display apparatus of claim 1 , wherein each of the first extension pattern and the second extension pattern is provided in plurality, the plurality of first extension patterns and the plurality of second extension patterns are alternately disposed along the first direction, the connection pattern is provided in plurality, and each of the plurality of connection patterns is disposed between corresponding first extension pattern and corresponding second extension pattern.

11. The display apparatus of claim 1 , wherein the protective member is provided as either a resin or a double-sided tape.

12. A display apparatus comprising:

a display panel which includes first display pads arranged in a first direction and second display pads disposed spaced apart from the first display pads in a second direction crossing the first direction and arranged in the first direction;

a main circuit board;

a first flexible circuit board which includes first substrate pads connected to the main circuit board and the first display pads, and a first driving chip connected to the first substrate pads;

a second flexible circuit board which includes second substrate pads connected to the main circuit board and the second display pads, and a second driving chip connected to the second substrate pads; and

protective members which includes a first protective member disposed on the first flexible circuit board and a second protective member disposed on the second flexible circuit board,

wherein the first flexible circuit board and the second flexible circuit board are bent in a direction toward a back surface of the display panel, and

wherein each of the first protective member and the second protective member comprises a first extension pattern and a second extension pattern which are spaced apart from each other along the first direction and extended along a second direction crossing the first direction, and a connection pattern which connects the first extension pattern and the second extension pattern and is extended along the first direction,

wherein the connection pattern of the first protective member covers the first driving chip and the connection pattern of the second protective member covers the second driving chip.

13. The display apparatus of claim 12 , wherein each of the first flexible circuit board and the second flexible circuit board comprises a lower surface and an upper surface facing the lower surface,

wherein the lower surface faces the back surface of the display panel when the first flexible circuit board and the second flexible circuit board are bent.

14. The display apparatus of claim 13 , wherein:

the first driving chip and the second driving chip are mounted on the lower surface of the first flexible circuit board and the lower surface of the second flexible circuit board, respectively;

the first protective member covers the first driving chip and a portion of the lower surface of the first flexible circuit board; and

the second protective member covers the second driving chip and a portion of the lower surface of the second flexible circuit board.

15. The display apparatus of claim 12 , wherein each of the first flexible circuit board and the second flexible circuit board further comprises:

a first portion which overlaps at least a portion of the main circuit board;

a second portion which overlaps at least a portion of the display panel; and

a third portion which connects the first portion and the second portion,

wherein when the first flexible circuit board and the second flexible circuit board are bent, the third portion has a relatively greater curvature than each of the first portion and the second portion.

16. The display apparatus of claim 15 , wherein:

the first driving chip is disposed in the first portion of the first flexible circuit board, and the first protective member covers the first driving chip; and
