Abstract

A plasma display device is disclosed. In an embodiment, the plasma display device includes a plasma display panel, a circuit board assembly, a chassis base, a signal transmission member, a cover plate, and a reinforcing member. The reinforcing member is assembled to an edge of the chassis base. The reinforcing member includes a main body and a protruding portion protruded therefrom. The protruding portion is protruded toward an internal surface of the cover plate. It secures a space, for the signal transmission member, between the main body and the cover plate.

Claims

1. A plasma display device, comprising:

a plasma display panel;

a circuit board assembly spaced apart from the plasma display panel;

a chassis base interposed between the plasma display panel and the circuit board assembly;

at least one driver integrated circuit package electrically connected to the plasma display panel and the circuit board assembly, and passing over at least one edge of the chassis base;

a reinforcing member connected to the edge of the chassis base; and

a cover plate covering the at least one driver integrated circuit package, wherein the cover plate has a surface facing the reinforcing member,

wherein the reinforcing member comprises a main body and at least one protruding portion extending from the main body,

and wherein the protruding portion extends toward the surface of the cover plate and maintains a space, for the at least one driver integrated circuit package, between the main body and the cover plate.

2. The device of claim 1, wherein the at least one driver integrated circuit package passes through the space.

3. The device of claim 1, wherein a gap is formed between the protruding portion and the surface of the cover plate.

4. The device of claim 3, wherein the gap is about 1.0 mm.

5. The device of claim 1, wherein the protruding portion contacts the surface of the cover plate.

6. The device of claim 1, wherein the at least one protruding portion includes a plurality of protruding portions spaced apart from each other.

7. The device of claim 6, wherein the at least one driver integrated circuit package includes a plurality of driver integrated circuit packages each package passing between adjacent protruding portions.

8. The device of claim 6, wherein the protruding portions are substantially equally spaced apart from each other.

9. The device of claim 1, wherein a surface of the main body is slanted near the circuit board assembly.

10. The device of claim 1, wherein a thickness of the reinforcing member is greater than a thickness of the chassis base.

11. The device of claim 1, wherein an inserting groove is formed on a surface of the reinforcing member such that the edge of the chassis base is inserted into the inserting groove.

12. The device of claim 1, wherein the reinforcing member extends along the edge of the chassis base.

13. The device of claim 1, wherein the reinforcing member is made of a metal.

14. The device of claim 1, wherein the reinforcing member is attached to the plasma display panel via a double-sided tape.

15. A plasma display device, comprising:

at least one signal transmission member connected to a plasma display panel and a driving circuit;

a cover plate covering at least in part the signal transmission member; and

a reinforcing member including a main body and at least one protruding portion extending from the main body,

wherein the at least one protruding portion is configured to maintain a space, for the at least one signal transmission member, between the main body and the cover plate.

16. The plasma display device of claim 15, wherein the at least one signal transmission member does not contact either of the main body and the cover plate when an external impact is applied to the cover plate.

17. The plasma display device of claim 15, wherein the cover plate has a surface facing the reinforcing member,

and wherein the protruding portion contacts the surface of the cover plate.

18. The plasma display device of claim 15, wherein the protruding portion has a cylindrical shape.

19. A method of using a plasma display device, comprising:

providing at least one signal transmission member connected to a plasma display panel and a driving circuit;

providing a cover plate covering at least in part the signal transmission member;

providing a reinforcing member including a main body and at least one protruding portion extending from the main body; and

preventing, by the use of the at least one protruding portion, the at least one signal transmission member from contacting either of the main body and the cover plate when an external impact is applied to the cover plate.

20. A plasma display device, comprising:

at least one signal transmission member connected to a plasma display panel and a driving circuit;

a cover plate covering at least in part the signal transmission member; and

a reinforcing member facing the cover plate, wherein at least one hole is defined in the reinforcing member, and wherein the at least one signal transmission member passes through the at least one hole.

21. The device of claim 20, wherein the reinforcing member contacts the cover plate.
