Embodiment
Below will combine accompanying drawing, the embodiment and the embodiment of the utility model specified, described specific embodiment in order to explain the utility model, is not the embodiment that is used to limit the utility model only.
So-called large scale liquid crystal module or large scale liquid crystal TV specifically are meant liquid crystal module or LCD TV more than 46 inches here.As shown in Figure 3, Fig. 3 is the explosive view of the utility model large scale liquid crystal module, and this liquid crystal module comprises metal frame 210, liquid-crystalline glasses (open cell), blooming piece (optical film), module backlight and backboard 250.Wherein, said metal frame 210 claims the face chase again or goes up chase (top cover), through after the surface treatment, can be directly as the fore shell of LCD TV, and integrated with realization TV module; Said liquid-crystalline glasses belongs to the core component in the liquid crystal module; Said blooming piece comprises diffusion sheet (diffuser sheet-u), following diffusion sheet (diffuser sheet-l) and diffuser plate (diffuser plant) etc., and the large scale liquid crystal module that has also is provided with press strip (holder) between blooming piece optical film and liquid-crystalline glasses; Said module backlight comprises reflector plate (reflector) and lamp bar (light bar); Reflector plate is sleeved on the LED lamp of lamp bar, and the lamp bar is arranged on the backboard 250, is provided with toward contact at the back side of backboard 250 and hangs the wall frame.
The improvement of the utility model liquid crystal module mainly is the mode of backboard splicing; In conjunction with shown in Figure 4; Fig. 4 is metal frame and the backboard of disassembling in the utility model large scale liquid crystal module under the state under the splicing state; Said backboard is made up of upper side frame 251, lower frame 252, left frame 253, left frame 254 and dull and stereotyped 255; The lower edge of said upper side frame 251 extends downward said dull and stereotyped 255 upper edge, and the upper edge of said lower frame 252 extends upward to said dull and stereotyped 255 lower edge, and said upper side frame 251, said lower frame 252 and said dull and stereotyped 255 are formed the bottom surface of said backboard; Said dull and stereotyped 255 left end is connected on the said left frame 253, and said dull and stereotyped 255 right-hand member is connected on the said left frame 254.
Owing to form the upper and lower side frame (frame-U/D) of the most of bottom surface of backboard and the aluminium that left and right side frame (frame-R/L) has adopted good heat dispersion performance, also improved the heat dissipation environment that is installed in lamp bar on the backboard bottom surface, improved the useful life of LED lamp.Even can also circuit directly be printed on the upper and lower side frame of aluminum substrate, to improve the radiating efficiency that the SMT mode mounts LED lamp on it.
In the preferred implementation of the utility model liquid crystal module, in conjunction with shown in Figure 5, Fig. 5 is vertical partial sectional view of the utility model large scale liquid crystal module; On said upper side frame 251, can be provided with the notch 256 of said liquid-crystalline glasses 101 of adaptive installation and blooming piece 102; Corresponding, on said lower frame and left frame and left frame, all can be provided with the groove of said liquid-crystalline glasses of adaptive installation and blooming piece, can replace the glue frame in traditional liquid crystal module thus; Under the cooperation of metal frame 210; Realize directly locking liquid-crystalline glasses 101 and blooming piece 102,, reduce the mould and the material cost of liquid crystal module with the structure of further simplification liquid crystal module.
Be further to reduce the die sinking risk of large scale liquid crystal module, can adopt aluminium extruded that integral forming process produces, and can adopt aluminium extruded that integral forming process produces as the left frame left frame as upper side frame and lower frame; Thus, upper side frame is the same with the lower frame part, opens a secondary mould and gets final product; Left frame is the same with left frame, also opens a secondary mould and gets final product, and total die sinking expense is less than 1.5 ten thousand RMB by standard in 2011; Die cost is ultralow, and the early investment risk is less, and parts processing is simple; Easy to assembly, sound construction.
Flat board as backboard bottom surface mid portion can adopt the cold-reduced sheet under the punch forming process to make; Two ends are connected to a fixed with left and right side frame respectively; Can lock at said flat board thus and pay the source circuit board of liquid-crystalline glasses open cell; Various pcb boards such as T-control control board and backlight driver plate with further simplified structure, reduce cost.
In addition, for can be directly as for the metal frame of LCD TV fore shell, equally also can be divided into four limit face frames up and down, and be connected on the frame up and down of forming backboard through screw is corresponding respectively.Different with prior art is that these four aluminium extrudeds that limit face frame also all can adopt integral forming process to produce with further reduction die sinking risk, reduce the up-front investment risk.
Based on above-mentioned large scale liquid crystal module; The utility model has also proposed a kind of large scale liquid crystal TV; Comprise the liquid crystal display module; Wherein: said liquid crystal display module is set to like each described large scale liquid crystal module among the above-mentioned embodiment, to reduce the die sinking investment risk, reduces the up-front investment cost.
Compare with the large scale liquid crystal module with LCD TV of the prior art, a kind of LCD TV that the utility model provided and large scale liquid crystal module have adopted the technological means of horizontal partition backboard bottom surface; Although splice nearly five of the parts of backboard; Yet because upper and lower side frame is the same, left and right side frame is the same, and middle flat part is simpler; But significantly reduced the quantity of mould thus; Thereby reduced the higher risk of die sinking expense, reduced the high cost cost of large scale liquid crystal module, overcome one of bottleneck of restriction large scale liquid crystal TV development.
Should be understood that the preferred embodiment that the above is merely the utility model is not sufficient to limit the technical scheme of the utility model; Concerning those of ordinary skills; Within the spirit and principle of the utility model, can increase and decrease according to above-mentioned explanation, replacement, conversion or improvement, for example; LCD TV that the utility model provided and liquid crystal module also may be used in the product below 46 inches; Can reduce number of molds equally, reduce the die sinking risk and reduce the cost cost, just its effect does not have the effect of product more than 46 inches remarkable; And all these increases and decreases, replacement, conversion or improve after technical scheme, all should belong to the protection range of the utility model accompanying claims.
