Abstract

A display apparatus includes: a substrate; a display layer located on a first surface of the substrate; a cover panel located on a second surface, opposite to the first surface, of the substrate; a printed circuit board located on the cover panel; a plurality of first terminals located on a first side of the printed circuit board; a plurality of second terminals spaced apart from the plurality of first terminals; a cover portion covering the printed circuit board; and a connection pattern located on a surface of the cover portion and arranged within a perimeter of the printed circuit board, wherein the surface of the cover portion faces the printed circuit board.

First claim

What is claimed is:

1 . A display apparatus comprising:
a substrate; a display layer located on a first surface of the substrate; a cover panel located on a second surface, opposite to the first surface, of the substrate; a printed circuit board located on the cover panel; a plurality of first terminals located on a first side of the printed circuit board; a plurality of second terminals spaced apart from the plurality of first terminals; a cover portion covering the printed circuit board; and a connection pattern located on a surface of the cover portion and arranged within a perimeter of the printed circuit board, wherein the surface of the cover portion faces the printed circuit board.

2 . The display apparatus of claim 1 , wherein the connection pattern connects the plurality of first terminals to the plurality of second terminals.

3 . The display apparatus of claim 2 , wherein the connection pattern comprises a plurality of linear patterns spaced apart from one another and parallel to one another, wherein each of the plurality of linear patterns connects a first-first terminal of the plurality of first terminals to a first-second terminal of the plurality of second terminals facing the first-first terminal.

4 . The display apparatus of claim 3 , wherein a width of each of the plurality of linear patterns is large enough such that each of the plurality of linear patterns completely covers the first terminal and the second terminal.

5 . The display apparatus of claim 3 , wherein a width of each of the plurality of linear patterns is less than each of an interval between the plurality of first terminals and an interval between the plurality of second terminals.

6 . The display apparatus of claim 3 , wherein a length of each of the plurality of linear patterns is greater than a distance between the first-first terminal and the first-second terminal.

7 . The display apparatus of claim 2 , wherein a thickness of portions of the connection pattern at a first-first terminal of the plurality of first terminals and at a first-second terminal of the plurality of second terminals is greater than a thickness of a portion of the connection pattern between the first-first terminal and the first-second terminal.

8 . The display apparatus of claim 1 , wherein the cover portion comprises an insulating material, and the connection pattern comprises a conductive material.

9 . The display apparatus of claim 8 , wherein the connection pattern is provided as a film comprising at least one of copper or aluminum.

10 . The display apparatus of claim 1 , wherein an adhesive layer is located between the cover portion and the connection pattern.

11 . A method of manufacturing a display apparatus, the method comprising:
bending a flexible circuit board connected to a substrate to face a rear surface of the substrate; providing a printed circuit board on a cover panel that is located on the rear surface of the substrate, wherein the printed circuit board is connected to the flexible circuit board; forming a connection pattern on a cover portion, wherein the connection pattern connects a plurality of terminals spaced apart from one another on the printed circuit board to each other when the cover portion is attached to the printed circuit board; and providing the cover portion on the printed circuit board.

12 . The method of claim 11 , wherein the connection pattern connects a plurality of first terminals of the plurality of terminals located on a first side of the printed circuit board to a plurality of second terminals of the plurality of terminals, wherein the plurality of second terminals is spaced apart from the plurality of first terminals.

13 . The method of claim 12 , wherein the connection pattern comprises a plurality of linear patterns that are spaced apart from one another and are parallel to one another.

14 . The method of claim 13 , wherein the forming of the connection pattern on the cover portion comprises forming the connection pattern so that a width of each of the plurality of linear patterns is less than each of an interval between the plurality of first terminals and an interval between the plurality of second terminals.

15 . The method of claim 13 , wherein the forming of the connection pattern on the cover portion comprises forming the connection pattern so that a length of each of the plurality of linear patterns is greater than a distance between a first terminal of the plurality of first terminals and a second terminal of the plurality of second terminals.

16 . The method of claim 13 , wherein the forming of the connection pattern on the cover portion comprises forming the connection pattern so that a thickness of portions of the connection pattern at a first terminal of the plurality of first terminals and at a second terminal of the plurality of first terminals is greater than a thickness of a portion of the connection pattern between the first terminal and the second terminal.

17 . The method of claim 11 , wherein the forming of the connection pattern on the cover portion comprises adhering the connection pattern to a surface of the cover portion facing the printed circuit board.

18 . The method of claim 11 , wherein the cover portion comprises an insulating material, and the connection pattern comprises a conductive material.

19 . The method of claim 18 , wherein the connection pattern is provided as a film comprising at least one of copper or aluminum.

20 . The method of claim 11 , wherein the providing of the cover portion on the printed circuit board comprises forming an adhesive layer on a surface of the cover portion facing the printed circuit board and adhering the cover portion to the printed circuit board.
