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 comprising electrodes;

a chassis base adjacent to the display panel, the chassis base supporting the display panel;

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

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

wherein a step structure is formed on the chassis base, the step structure protruding towards the flexible printed circuit where the flexible printed circuit is attached to the chassis base, the step structure creating a gap between the chassis base and the flexible printed circuit; and

wherein the driver integrated circuit creates a gap between the flexible printed circuit and the protective plate.

2. The display device of claim 1, wherein the driver integrated circuit, facing a 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 integral with the chassis base.

4. The display device of claim 1, wherein the step structure is a separate structure from the chassis base.

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

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

7. The display device of claim 1, wherein the driver integrated circuit is in a type carrier package.

8. The display device of claim 1, further comprising a damping means 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.
