Abstract

A flat panel display includes a bezel having a first substrate part and a second substrate part perpendicularly extending from one side of the first substrate part. A flexible printed circuit board is attached to the second substrate part by a conductive tape, and electrostatic discharge and damage caused by external mechanical interference can be prevented.

Claims

1. A flat panel display device, comprising:

a bezel including a first substrate part having a bent part at an edge of the first substrate part, and a second substrate part extending from one side of the first substrate part and beyond the bent part of the first substrate part;

a flat display panel arranged within the first substrate part of the bezel, and the flat display panel including a pad part and a pixel region; and

a flexible printed circuit board connected to the pad part and electrically connected to the second substrate part of the bezel, with an entirety of one major surface of the flexible printed circuit board facing toward the bezel.

2. The flat panel display device according to claim 1, wherein the second substrate part horizontally extends from the first substrate part.

3. The flat panel display device according to claim 1, wherein the second substrate part is of the same material as the first substrate part.

4. The flat panel display device according to claim 1, further comprising a conductive tape to attach the flexible printed circuit board to the second substrate part.

5. The flat panel display device according to claim 1, wherein the bent part is hemmed.

6. The flat panel display device according to claim 1, further comprising a cushion tape, having an adhesive on both surfaces thereof, to attach the flat display panel to the first substrate part of the bezel.

7. The flat panel display device according to claim 6, wherein the cushion tape comprises an open celled microcellular polyurethane material.

8. The flat panel display device according to claim 1, wherein the bezel comprises an electrically conductive metallic material.

18. The flat panel display device according to claim 1, wherein:

the second substrate part is made of the same material as the first substrate part; and

the second substrate part has an aperture therein.

9. A flat panel display device, comprising:

a bezel including a first substrate part having a bent part at an edge of the first substrate part, and a second substrate part extending from one side of the first substrate part and beyond the bent part of the first substrate part;

a flat display panel arranged within the first substrate part of the bezel, and including a pad part and a pixel region; and

a flexible printed circuit board connected to the pad part and electrically connected to the second substrate part of the bezel;

wherein the second substrate part has an aperture therein.

10. The flat panel display device according to claim 9, wherein an electronic component is arranged within the aperture.

11. The flat panel display device according to claim 9, wherein the second substrate part horizontally extends from the first substrate part.

12. The flat panel display device according to claim 9, wherein the second substrate part is of the same material as the first substrate part.

13. The flat panel display device according to claim 9, further comprising a conductive tape to attach the flexible printed circuit board to an edge of the aperture in the second substrate part.

14. The flat panel display device according to claim 9, wherein the bent part is hemmed.

15. The flat panel display device according to claim 9, further comprising a cushion tape, having an adhesive on both surfaces thereof, to attach the flat display panel to the first substrate part of the bezel.

16. The flat panel display device according to claim 15, wherein the cushion tape comprises an open celled microcellular polyurethane material.

17. The flat panel display device according to claim 9, wherein the bezel comprises an electrically conductive metallic material.

19. A flat panel display device, comprising:

a bezel including a first substrate part having a bent part at an edge of the first substrate part, and a second substrate part extending from one side of the first substrate part;

a flat display panel arranged wholly within the first substrate part of the bezel, and the flat display panel including a pad part and a pixel region; and

a flexible printed circuit board connected to the pad part and electrically connected to the second substrate part of the bezel, with a geometrical projection of a major surface of the flexible printed circuit board forming a flat continuum against the bezel.

20. The flat panel display device according to claim 19, wherein the second substrate part has an aperture accessed by the flexible printed circuit board.
