Abstract

An electrical plasma display comprises a display panel; a heat radiator fixed on a rear substrate of the display panel for displaying radiation of the panel; a heat interface layer positioned between the display panel and the heat radiator for displaying excellent contact and heat transmission of display panel and the heat radiation, the heat interface layer is made of carbon nanotube materials; wherein the heat radiator comprises a plurality of heat sinks, the substrate is one-way heat conduction substrate made of one-way heat conduction material for conducting heat from display panel to a plurality of heat sinks.

Description

【Technical field】 [0001] The invention relates to a plasma display, in particular to a plasma display with a cooling device. 【Background technique】 [0002] Plasma display is to inject inert gas or mercury gas into the discharge tank made of vacuum glass tube, and then use high voltage to make the gas produce plasma effect, and emit ultraviolet light to bombard the phosphor to emit visible light. The color of visible light is determined by the type of phosphor, and the image of a plasma display is formed by the arrangement and combination of many small grids similar to fluorescent lamps. [0003] In the application field of large-size displays, compared with LCD (liquid crystal display) and CRT (cathode ray tube display), plasma displays have the characteristics of thin thickness, light weight, wide viewing angle, large-size and high-quality digital display and other characteristics. However, because the inert gas needs to be under the action of high voltage to generate gas...
