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 printed circuit board unit comprising:
a first printed circuit unit; a second printed circuit unit electrically connected to the first printed circuit unit; an opening defined between the first printed circuit unit and the second printed circuit unit; and a connection member coupled to each of the first printed circuit unit and the second printed circuit unit to electrically connect the first printed circuit unit and the second printed circuit unit.

2 . The printed circuit board unit of claim 1 , further comprising one or more holes defined between the first printed circuit unit and the second printed circuit unit.

3 . The printed circuit board unit of claim 1 , wherein the connection member covers the opening and electrically connects the first printed circuit unit and the second printed circuit unit.

4 . The printed circuit board unit of claim 3 , wherein the connection member comprises:
a first coupling part coupled to the first printed circuit unit; a second coupling part coupled to the second printed circuit unit; and a connection part connecting the first coupling part to the second coupling part and covering the opening, wherein the first coupling part meets the connection part at a bent portion, and the second coupling part meets the connection part at a bent portion.

5 . The printed circuit board unit of claim 4 , wherein the connection part comprises one or more surfaces joined at an angle.

6 . The printed circuit board unit of claim 1 , wherein the connection member comprises:
a first coupling part coupled to the first printed circuit unit; a second coupling part coupled to the second printed circuit unit; and a connection part connecting the first coupling part to the second coupling part by extending around the opening.

7 . The printed circuit board unit of claim 6 , wherein one side of the connection part that faces the opening has a bent portion.

8 . A display apparatus comprising:
a display panel displaying an image and curved in a first direction to have a curvature; a printed circuit board comprising a first printed circuit unit electrically connected to the display panel, a second printed circuit unit electrically connected to the display panel, and an opening defined between the first printed circuit unit and the second printed circuit unit; and a connection member electrically connecting the first printed circuit unit and the second printed circuit unit while allowing the first printed circuit unit to move relative to the second printed circuit unit, wherein the connection member adapts to the positions of the first printed circuit unit and the second printed circuit unit.

9 . The display apparatus of claim 8 , wherein the connection member comprises:
a first coupling part coupled to the first printed circuit unit; a second coupling part coupled to the second printed circuit unit; and a connection part connecting the first coupling part to the second coupling part.

10 . The display apparatus of claim 9 , wherein the connection member covers the opening, and the first coupling part joins the connection part to form a bent portion, and the second coupling part joins the connection part to form a bent portion.

11 . The display apparatus of claim 8 , wherein the relative positions of first printed circuit unit and the second printed circuit unit change according to the curvature.

12 . The display apparatus of claim 9 , wherein the connection part extends around the opening, and the side of the connection part facing the opening has a bent portion.
