Abstract
The invention discloses a plasma display module. The plasma display module is characterized by comprising a plasma display panel, a back panel and an adhesive spacer, wherein the plasma display panel consists of an upper glass substrate and a lower glass substrate and is used for displaying images; the back panel supports the plasma display panel and releases heat produced by the plasma display module; the adhesive spacer is bonded between the plasma display panel and the back panel; and the spacer is made of a composite material which is obtained by mixing butyl rubber, piezoelectric material particulate powder, conductive material particulate powder and heat conductive material particulate powder. Electric energy produced by piezoelectric effect is converted into heat energy for dissipating, so that better noise reduction effect is achieved; and the spacer has high heat conducting performance, so that heat energy produced by the plasma display panel can be effectively released to the back panel.

As depicted in figs. 1 and 2, a plurality of circuit boards 40 of the Plasmia indicating panel 10 that plasma demonstration module mainly is made up of top glass substrate 11 and lower glass substrate 12, adhesive tape 20, backboard 30, driving Plasmia indicating panel image constitute, Plasmia indicating panel 10 pastes backboard 30 by adhesive tape 20, and a plurality of circuit boards 40 that drive the Plasmia indicating panel image are fixed on the backboard by the rivet on the backboard 31.
In Plasmia indicating panel, discharge gas is sealed between the top glass substrate 11 and lower glass substrate 12 with a plurality of electrodes, provide discharge gas producing ultraviolet ray, and the ultraviolet ray excited fluorescence coating that forms in predetermined display unit sends visible light, obtain image thus.
Plasma shows that module regulates the display unit discharge according to video data and hold time, and promptly keeps the number of times of discharge, thereby realizes showing the gray scale that needs.
Like this, in order to produce dynamic image, show the high-tension drive signal of using in the module of high-frequency at plasma, can make the Plasmia indicating panel of forming by top glass substrate 11 and lower glass substrate 12 10 produce a large amount of heat and noise, also can emit than color cathode ray tube or the more electromagnetic wave of display panels simultaneously.
Summary of the invention
Goal of the invention of the present invention is: the invention is in order to address the above problem, a kind of pad that sticks between Plasmia indicating panel and the backboard is being provided between Plasmia indicating panel and the backboard, the heat release that can effectively Plasmia indicating panel be produced is to backboard, effectively eliminate the noise that Plasmia indicating panel produces simultaneously, and can be by absorbing the electromagnetic wave that plasma panel produces.
In order to reach such purpose, the pad in the invention has used composite material.Composite material is to be mixed by butyl rubber, piezoelectric particulate powder, electric conducting material particulate powder and Heat Conduction Material particulate powder.
Show in the module operating state at plasma, except traditional damping mode continuation performance noise abatement sound effect of butyl rubber material, piezoelectric particulate powder in the composite material, again with a part of vibration mechanical energy, become electric energy, and, rely on Joule effect by compound electric conducting material particulate powder of entering of while, the electric energy that piezoelectric effect is produced becomes thermal dissipation, thereby obtains better noise abatement audio fruit.
Show that at plasma in the module operating state, because the Heat Conduction Material particulate powder in the composite material, pad of the present invention possesses good heat-conductive characteristic, the heat release that can effectively Plasmia indicating panel be produced is to backboard.
Show that at plasma the die worker does in the state, because the electric conducting material particulate powder in the composite material, pad of the present invention possesses excellent conducting performance, can be by absorbing the electromagnetic wave that plasma panel produces.
Pad in the invention sticks between Plasmia indicating panel and the backboard.
The thickness of the pad in the invention is for being 0.3 to 2mm.
Invention among the application provides a kind of adhesive pad, to be different from the mode of such scheme, propose a kind of new plasma that can effectively improve equally and show the temperature characterisitic of module and can effectively reduce the adhesive sheet that plasma shows the noise of module that its novelty is embodied in the following aspects:
1) proposed a kind of stick on thickness between Plasmia indicating panel and the backboard 0.3 to the new adhesive pad of 2mm.
2) this adhesive pad has used composite material.Composite material is to be mixed by butyl rubber, piezoelectric particulate powder, electric conducting material particulate powder and Heat Conduction Material particulate powder.
3) show in the module operating state at plasma, except traditional damping mode continuation performance noise abatement sound effect of butyl rubber material, piezoelectric particulate powder in the composite material, again with a part of vibration mechanical energy, become electric energy, and, rely on Joule effect by compound electric conducting material particulate powder of entering of while, the electric energy that piezoelectric effect is produced becomes thermal dissipation, thereby obtains better noise abatement audio fruit.
4) show that at plasma in the module operating state, because the Heat Conduction Material particulate powder in the composite material, pad of the present invention possesses good heat-conductive characteristic, the heat release that can effectively Plasmia indicating panel be produced is to backboard.
5) show that at plasma the die worker does in the state, because the electric conducting material particulate powder in the composite material, pad of the present invention possesses excellent conducting performance, can be by absorbing the electromagnetic wave that plasma panel produces.
6) evade present plasma and show that module is used to reduce noise, improves temperature characterisitic and improves the patent problem of Electro Magnetic Compatibility technology.
