Description
Technical field
The present invention relates to image display device, particularly, the present invention relates to have the image display device of slab construction, wherein improved the fixing means of display panel.The present invention is specifically related to plasm display device.
Background
Known, because advancing and developing of the TV tech that realizes so far has the image display device large-scale production economically of cathode ray tube (CRT).But in recent years, the flat-panel monitor that thickness is littler and weight is lighter received publicity all the more, because image display device of future generation will substitute the CRT image display device.
A kind of typical flat display board is LCD (LCD), and it has been used as the compact display of notebook personal computer, cell phone, PDA(Personal Digital Assistant) and other personal digital assistant device.On the other hand, plasma display panel (PDP) is the representative instance of this flat-panel monitor, and it has less thickness and bigger display screen.In the practice, it has been used for commercial the application, and current just as the wall hanging TV set of family expenses.
For simple declaration, PDP50 shown in Figure 1 only has a discharge display cells 56, but generally comprises a large amount of fine discharge display units.Each discharge display cells 56 all is separated from each other and relative substrate of glass limits by a pair of, i.e. front surface glass substrate 61 and rear surface substrate of glass 51, and reinforcement 54 has micro-structure and is arranged between these substrate of glass with reservation shape.Have the transparent display electrode 63, transparency dielectric layer 62 and the protective clear layer 64 that constitute by scan electrode and maintenance electrode on the front surface glass substrate 61.Have address electrode 53 and dielectric layer 52 on the rear surface substrate of glass 51.Have scan electrode and keep each show electrode 63 of electrode cross each address electrode 53 and with the gap by the predetermined pattern setting.Each discharge display cells 56 all has the phosphorus layer 55 on its inwall, and rare gas (such as Ne-Xe gas) is sealed in the unit 56, shows thereby form the self-luminous emission when plasma discharge occurring between electrode.
Generally, PDP is fixed in the aluminium frame, so that use.Because it uses substrate of glass, PDP has suitable weight (general about 8 to 10kg).For avoiding PDP to peel off easily or falling, adopt a kind of method PDP to be fixed on a plurality of positions traditionally by using powerful double-faced adhesive tape that PDP is attached on the framework or by the use fixed screw.In addition, because plasma discharge, at the heat of PDP duration of work generation certain degree, and temperature generally reaches about 80 to 90 ℃.Therefore, between framework and PDP, sandwich heat exchange sheet or heat conduction bonding sheet traditionally to improve thermal radiation effect.
For example, open (Kokai) No.2001-11402 of the special permission of Japanese unexamined has disclosed plasm display device shown in Figure 2.This plasma display unit comprises PDP71, heat radiation plate 72 and is clipped in therebetween radiation adhesive sheet 73.Bonding sheet 73 is made of the heat radiation sticky ingredient that comprises viscosity and heat conduction agent.A large amount of ridges 74 are formed on the surface of bonding sheet 73 to guarantee level and smooth binding operation and to avoid air entrapment.But, when the heat radiation bonding sheet was incorporated on the whole surface of PDP by the mode that can not be stripped from, several problems had appearred.For example, when any defective occurring in process of production, just can not remove heat radiation plate (chassis base) and reuse it from defective plate.When occurring any fault in the PDP at work or when damaged, can not only remove the PDP place under repair and also can not change with new PDP.In addition, handle or recirculation during the stage when PDP reaches, PDP and heat radiation plate separate unsatisfactorily, because the bond strength between them is very strong, and this has proposed problem to smoothing processing and recirculation.Even PDP and heat radiation plate can be separated, the remaining of adhesive also appears on these elements inevitably.
For fear of passing through to use bonding sheet in conjunction with the problems referred to above in PDP and the chassis base, open (Kokai) No.10-319863 of the special permission of Japanese unexamined has disclosed plasm display device shown in Figure 3.Plasm display device 80 comprises shell 82, and it has front casing 84 and rear casing 86, and internal element 83.Front casing 84 has been equipped with the shaded portions 81b that is made by glass.The heat exchange sheet 88 that internal element 83 has aluminium chassis base plate 89, PDP87 and made by silicon.Because this plasma display unit 80 has adopted a kind of structure, wherein screw 92 is fitted into a plurality of fixed lobe portions (boss) 91 of installing on the rear surface of PDP87, PDP87 can be fixed on the base plate 89 removedly.But when by using this fixed screw fixedly during PDP, it is complicated that structure becomes, and assembles required number of elements increase and manufacturing cost and rise inevitably.Because the screw fixing operation also is pretty troublesome, need a kind of more easily can be removedly the fixing method of PDP.
Summary of the invention
