Abstract

Provided is a method of manufacturing a display apparatus. The method includes: preparing a printed circuit board including a first printed circuit unit and a second printed circuit unit; providing, on the printed circuit board, a connection member electrically connecting the first printed circuit unit to the second printed circuit unit; coupling one end of a tape carrier package to the printed circuit board; coupling the other end of the tape carrier package to a display panel; and cutting the printed circuit board into the first printed circuit unit and the second printed circuit unit that move relative to each other.

First claim

What is claimed is:

1. A method of manufacturing a display apparatus, the method comprising:
preparing a printed circuit board comprising a first region, a second region, and a third region wherein the second region is between the first region and the third region, the first region including a first printed circuit unit, the third region including a second printed circuit unit, and the second region having an opening;
providing, on the printed circuit board, a connection member electrically connecting the first printed circuit unit and the second printed circuit unit;
coupling a first end of a connection film to a display panel;
coupling a second end of the connection film to the printed circuit board; and
cutting the second region to divide the printed circuit board into the first printed circuit unit and the second printed circuit unit;
wherein after the connection film is attached to the display panel and the printed circuit board, the printed circuit board is divided into the first printed circuit unit and the second printed circuit unit.

2. The method of claim 1 , further comprising bending the display panel in a first direction,
wherein the first region, the second region, and the third region are arranged in the first direction.

3. The method of claim 2 , further comprising forming one or more holes in the second region,
wherein the second region on which the holes are formed is cut to divide the printed circuit board into the first printed circuit unit and the second printed circuit unit.

4. The method of claim 1 , wherein the connection member is provided on the printed circuit board to cover at least part of the opening.

5. The method of claim 4 , wherein the connection member comprises a first coupling part, a second coupling part, and a connection part connecting the first coupling part to the second coupling part, and
the providing of the connection member comprises:
bending a first boundary between the first coupling part and the connection part;
bending a second boundary between the second coupling part and the connection part;
electrically connecting the first coupling part to the first printed circuit unit; and
electrically connecting the second coupling part to the second printed circuit unit,
wherein the first boundary and the second boundary are spaced apart from each other.

6. The method of claim 1 , wherein the connection member comprises a first coupling part, a second coupling part, and a connection part connecting the first coupling part to the second coupling part without covering the opening, and
the providing of the connection member comprises:
electrically connecting the first coupling part to the first printed circuit unit; and
electrically connecting the second coupling part to the second printed circuit unit.

7. The method of claim 6 , wherein one side of the connection part has a bent portion in plan view, the one side of the connection part facing the opening.

8. The method of claim 1 , wherein after the printed circuit board is divided into the first printed circuit unit and the second printed circuit unit, the display panel is curved in a first direction.
