Problems solved by technology

In this way, heat sinks (310, 320, 330, 340) cannot effectively dissipate the heat generated by each board (210, 220, 230, 240) to the outside, which will cause the switch components on the board (210, 220, 230, 240) to fail. Action or damage, leading to a decrease in the reliability of the plasma display panel
At the same time, the expensive price of aluminum materials will lead to an increase in the price of plasma display panels
Moreover, the noise generated when each plate (210, 220, 230, 240) works cannot be cut off

Embodiment Construction

[0040] Hereinafter, embodiments of the plasma display device of the present invention will be described in detail with reference to the accompanying drawings.

[0041] Figure 5 It is a perspective view showing a plasma display device to which a heat sink portion is attached in an embodiment of the present invention.

[0042] like Figure 5 As shown, the plasma display device consists of a driving plate (510, 520, 530, 540) for inputting driving pulses on the plasma display panel and a carbon fiber material that dissipates heat generated by the driving plate (510, 520, 530, 540) to the outside. The heat sink portion (600) constitutes.

[0043] First, the driving board part (510, 520, 530, 5400) is formed on the frame (500), which includes the Y driving board (510), the Z maintaining board (520), the data driving board (530) and the control board (540) Wait.

[0044] The Y driving board (510) drives the scanning electrode lines (Y1 or Ym) of the plasma display panel (550) f...

Abstract

The invention relates to a plasma display device that could emit heat generated from driving board to external. It includes the following sections: driving board that could input driving impulse on plasma display panel, and heat emission sheet. The feature is that the shape of the heat emission sheet. It could decrease the false operation and improve reliability of plasma display panel. Because of low cost carbon fiber, the cost of plasma display panel would be very low. It also has the effect of cutting off noise generated from driving board.

Description

technical field [0001] The present invention relates to a plasma display device, and more specifically, it relates to a plasma display device provided with a heat sink for dissipating heat generated on a driving board to the outside. Background technique [0002] In general plasma display panels, the partitions formed between the front panel and the rear panel become units or grids, and each unit is filled with main discharge gas such as neon, helium or a mixture of neon and helium, and an inert gas containing a small amount of xenon. Gas. When high-frequency voltage causes discharge, the inert gas generates vacuum ultraviolet rays and makes the light formed between the partitions to display the picture. Such a plasma display structure such as figure 1 Indicated. [0003] figure 1 It is a perspective view showing the structure of a general plasma display panel. [0004] like figure 1 As shown, the plasma display panel is composed of a front substrate (100) formed by arr...
