Abstract

A display device including a display panel, a chassis base connected to the plasma display panel, the chassis base supporting the plasma display panel, and a flexible printed circuit having a driver integrated circuit thereon installed on the chassis base while being pressed by a protective plate. A step structure is formed on the chassis base where the flexible printed circuit is attached. Furthermore, the flexible printed circuit area where the driver integrated circuit is placed may be in contact with a heat dissipating material located in an accommodating portion formed in the chassis base.

Claims

1. A display device comprising:

a display panel;

a chassis base positioned parallel to the display panel, the chassis base supporting the display panel;

a flexible printed circuit placed on a surface of the chassis base, the flexible printed circuit having a driver integrated circuit thereon and extending to the electrodes of the display panel for the electrical connection; and

a protective plate placed adjacent to the flexible printed circuit, the protective plate pressing the flexible printed circuit to the chassis base,

wherein a step structure is formed on the chassis base where the flexible printed circuit is attached.

2. The display device of claim 1, wherein the driver integrated circuit, facing the top of the step structure is in contact with the top surface of the step structure.

3. The display device of claim 1, wherein the step structure is formed as a single body with the chassis base itself.

4. The display device of claim 1, wherein the step structure is formed as a separate structure to be installed on the chassis base.

5. The display device of claim 1, wherein the step structure is formed by a protruded area in part facing opposite the display panel.

6. The display device of claim 5, wherein a heat dissipating sheet is placed between the flexible printed circuit and the protective plate.

7. The display device of claim 1, wherein the driver integrated circuit is packed in the type carrier package and installed on the flexible printed circuit.

8. The display device of claim 1, further comprising a damping means placed between the flexible printed circuit and the step structure.

9. The display device of claim 8, wherein the damping means is located in an accommodating portion that is formed on the step structure, and the driver integrated circuit facing the damping means is in contact with the damping means.

10. The display device of claim 8, wherein the step structure is formed as a single body with the chassis base itself.

11. The display device of claim 8, wherein the step structure is formed as a separate structure to be installed on the chassis base.

12. The display device of claim 8, wherein the step structure has a protruded area facing the display panel and a protruded area facing opposite the display panel.

13. The display device of claim 12, wherein a heat dissipating sheet is placed between the flexible printed circuit and the protective plate.

14. The display device of claim 8, wherein the driver integrated circuit is packed in the type carrier package and installed on the flexible printed circuit.

15. The display device of claim 1, wherein the display panel is a plasma display panel.

16. A display device comprising:

a display panel;

a chassis base positioned parallel to the display panel, the chassis base supporting the display panel;

a flexible printed circuit placed on a surface of the chassis base, the flexible printed circuit having a driver integrated circuit on and extending to electrodes of the display panel for electrical connection; and

a protective plate placed adjacent to the flexible printed circuit, the protective plate pressing the flexible printed circuit to the chassis base,

wherein the flexible printed circuit area where the driver integrated circuit placed is in contact with a heat dissipating material located in an accommodating portion formed in the chassis base.

17. The display device of claim 16, wherein the accommodating portion is formed into the shape of a cavity on the chassis base.

18. The display device of claim 16, wherein the accommodating portion is formed into the shape of a cavity on a reinforcing means installed on the chassis base.

19. The display device of claim 18, wherein the reinforcing means is formed of solid material having high thermal conductivity.

20. The display device of claim 19, wherein the reinforcing means is formed of one of the materials selected from aluminum, copper, or steel.

21. The display device of claim 16, where the heat dissipating material is in gel-phase.

22. The display device of claim 16, further comprising a cover plate installed on the chassis base, the cover plate pressing the driver IC.

23. The display device of claim 16, wherein the display panel is a plasma display panel.
