Problems solved by technology

[0012] However, in order to ensure the flexibility of the heat dissipation sheet layer (150), it is made into a roll (Roll) shape, but the thickness of the heat dissipation sheet (151) is required to be thin enough when the roll shape is made, so the thermal conductivity decreases, resulting in the inability to quickly emit plasma display. The heat generated by the drive of the device

Embodiment Construction

[0033] A reliable implementation example of the present invention will be described in more detail with reference to the following drawings.

[0034] FIG. 3 is a diagram showing a plasma display device in the present invention.

[0035] As shown in Figure 3, the plasma display device is composed of the following parts: a casing (310) including a front cover (311) and a back cover (Back cover, 312) that determine the shape; A plasma display panel (320) that excites phosphors caused by vacuum ultraviolet rays to display images; a driving device (330) including a PCB for driving and controlling the plasma display panel; connected to the driving device, and dissipates heat when the plasma display device is driven and supports the plasma display panel a frame (340); a first sheet layer (350) combining the plasma display panel with the frame and performing heat dissipation; a second sheet layer (360) combining with the first sheet layer (350). The second sheet layer (360) formed in...

Abstract

The invention relates to plasma display device that includes plasma display panel, frame, first film layer formed between frame and plasma display panel, and at least one second film layer. Heat emission function is formed on the first film. The second film layer could cut off and absorb electromagnetic wave. It could effectively improve the heat emission function of plasma display device.

Description

【Technical field】 [0001] The present invention relates to a plasma display device, and more specifically relates to a plasma display device which improves the heat dissipation sheet layer so that its heat dissipation function is improved and electromagnetic waves can be cut off and absorbed. 【Background technique】 [0002] A general plasma display panel (Plasma Display Panel) forms a box wall between the front panel and the rear panel, and forms a grid of cells between the box walls, and fills each grid with neon (Ne), helium, etc. (He) or a mixed gas of neon and helium (Ne+He) and a small amount of inert gas such as xenon. When discharging by high-frequency voltage, the inert gas generates vacuum ultraviolet rays, and the phosphor between the walls emits light to display the screen. Since such a plasma display panel can realize a thin and light structure, it is attracting attention as a next-generation display device. [0003] A plasma display device ...
