Abstract
The radiation structure of elatroluminescent display element of the utility model adheres a black lead layer on the board of the elatroluminescent display element and passes through the black lead layer to combine with an aluminum board layer so as to cause an anisotropic heat conduction function composed of the black lead layer to be formed between the aluminum board layer and the elatroluminescent display element; the heat source of the elatroluminescent display element is quickly conducted to the aluminum board layer for leading out by the black lead layer; the heat source of the aluminum board layer corresponding to the other side of the elatroluminescent display element is caused to be homogeneously distributed on the whole black lead layer so as to prevent the heat source from conducting to the elatroluminescent display element. As a consequence, the purpose of prolonging the service life of the elatroluminescent display element is obtained.
Description
Technical field
The utility model relates to the electroluminescent display device heat dissipation technology that plasma display panel (PDP), active display (OLED) etc. belong to self-emitting display, aims to provide one and effectively prolongs the electroluminescent display device heat-dissipating structure in useful life.
Background technology
Press, the TV of the reflection tubular type of often seeing in the family is called for short CRT now, be to belong to electron excitation display (Cathodoluminescence), its principle is that electron beam quickens because of high pressure, get on the iconoscope that plates one deck phosphor material, electron beam is through magnetic field, makes the path produce deviation and beats on the diverse location of iconoscope, and screen coating one deck fluorescent substance material produces RGB three looks with the tri-barrel electron gun bump respectively.
Because deflecting coil (yoke) is difficult for making electron beam to do significantly deflection, so screen is big more, electron beam just needs longer ranging offset, so the CRT monitor volume is big and the screen camber, though can solve the problem of CRT screen camber with the mode that the electromagnetic lens group is done correction with electron beam, and become so-called whole plane TV; But owing to the big Heavy Weight of CRT volume, take analogy interface, the more harmful vision health of radiation, so do not meet the development trend of following consumer electronics.
Therefore, domestic and international many photoelectricity science and technology dealers are devoted to the exploitation of display of new generation invariably, in the hope of the display of more frivolous, a low radiation can be provided; Wherein, to be tending towards ripe display of new generation then be that plasma display panel (PDP), membrane transistor LCD (Liquid Crystal), active display (OLED) etc. are arranged to technology.
In the middle of display of new generation, because so the liquid crystal of TFT-LCD itself can luminously must not add light source, also owing to need the design of backlight, so the power consumption of TFT-LCD is bigger and heavy than self luminous PDP or OLED's, for light source being evenly distributed in the every nook and cranny of screen, so the assistance of light guide plate will be arranged.Add TFT-LCD 30 cun still too high with Heaven size product cost, have on color saturation, visual angle, answer speed and the brightness problem to be overcome, so the large scale product is more competitive with PDP TV in a short time.
As shown in Figure 1, be in the streets being seen at present plasma display panel (PDP, PlasmaDisplay Panel) basic composition configuration diagram, its plasma display panel is based on an electroluminescent display device 10, and its electroluminescent display device 10 is inert gas injecting or mercury gas in the discharge space (that is vacuum glass space) that two face glasss 11 are constituted, and then through drive circuit 20 alive modes, make discharge space gas inside generation discharge (electricity slurry effect just) and discharge ultraviolet, shine the fluorescent material 12 that is coated on face glass 11 walls by ultraviolet light, make fluorescent material 12 be inspired visible light, so as to reaching " self-luminous " display effect.
That is, as long as the fluorescent material that coating is different, will inspire the visible light of different colours, so PDP gets together hundreds thousand of the fluorescent tubes (discharge space just) that dwindle, in each discharge space, inject then and be mixed with neon (Ne) and xenon (Xe), or the inert gas that mixes with xenon (Xe) of helium (He), and coating is red in these hundreds thousand of discharge spaces, blue, green trichromatic fluorescent material, cooperate drive circuit to make the gas of these hundreds thousand of discharge spaces produce electric discharge phenomena, send ultraviolet, excite the fluorescent material that is coated on the discharge space inwall to make it produce visible light, see through suitable image signal again and handle, just three primary colors can be mixed into colored image.
Yet, because " self-luminous " display mode of PDP, might be subjected to the temperature effect that light source produces and reduce the usefulness of display, the effect that therefore must see through heat-dissipating structure make the thermal source of electroluminescent display device be shed to avoid and cause wearing out of electroluminescent display device because of the effect of temperature, as shown in Figure 1, the present known radiator structure of electroluminescent display device 10, it mainly is the aluminum layer 40 that the panel at electroluminescent display device 10 utilizes heat-conducting layer 30 to cohere, the light source that electroluminescent display device 10 is produced with the conduction of heat of utilizing heat-conducting layer 30 is passed to aluminum layer 40 and sheds, but comprise power supply unit owing to correspond to electroluminescent display device 10 other sides at aluminum layer 50, drive circuits such as integrated circuit 20 also can produce thermal source, its thermal source can see through aluminum layer 40 equally, heat-conducting layer 30 is back to electroluminescent display device 10, not only can the radiating effect of electroluminescent display device 10 be impacted, can therefore cause the temperature Centralized of electroluminescent display device 10 even, become the factor that electroluminescent display device 10 wears out on the contrary.
