Problems solved by technology

The temperature rise caused by the power supply module 24 supplying various driving voltages is the main reason for hindering the normal operation of the power supply module 24
[0022] Therefore, due to the rise in temperature, the panel 4 and the driving device, that is, each constituent element of the printed circuit board 10, cannot perform normal operations.

Embodiment Construction

[0063] Next, referring to FIG. 3 to FIG. 9, the embodiment of the plasma display panel of the present invention will be described in detail.

[0064] Fig. 3 is a schematic diagram showing a plasma display panel of the present invention.

[0065] As shown in FIG. 3 , the plasma display panel of the present invention includes a front case 52 and a rear case 62 , a panel 54 , a heat dissipation case 56 , a frame 58 and a printed circuit board 60 .

[0066] The panel 54 is composed of an upper substrate 54a and a lower substrate 54b. Several scan electrodes and several sustain electrodes are provided on the upper substrate 54a. The lower substrate 54b includes the following components: several address electrodes arranged in a crossing state with the scan electrodes and the sustain electrodes; and a phosphor layer arranged on the upper surface of the lower substrate. Utilize the ultraviolet rays generated between each scan electrode, sustain electrode and address electrode to exc...

Abstract

This invention relates to one plasma display panel, which uses gas discharge gas for picture display panel and comprises the following parts: multi-chip module to generate above electricity signal by use of switch; power supply module to generate drive signals to provide electricity to above module; heat dissipation slice to release above power module; temperature sensor to test above dissipation slice temperature to generate temperature data; feedback controller to echo the above data to generate switch control signals.

Description

technical field [0001] The present invention relates to the technology of the plasma display panel, and specifically relates to a plasma display panel which can be stably driven by lowering the driving temperature. Background technique [0002] The cathode ray tube (Cathod Ray Tube: CRT) or Braun tube, which has always been the mainstream of image display devices, has recently developed many types that can overcome the shortcomings of this cathode ray tube due to its shortcomings of large size and heavy weight. Flat panel display devices, and have a great tendency to replace the existing cathode ray tubes. [0003] Such flat panel display devices mainly include liquid crystal displays (Liquid Crystal Display: LCD), plasma displays (PDP: Plasma Display Panel), field emission display devices (Field Emission Display: FED), electroluminescent displays (Elcctro Luminescence: EL), etc. type. [0004] Plasma displays are particularly attractive among flat panel displays because t...
