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.
A kind of LCD of the utility model, LCD as shown in Figure 1, shown in Figure 1 comprises LCDs and base 130.Wherein, frame 120 and back cover before LCDs comprises, in the present embodiment, back cover adopts the backboard 110 in the module backlight to substitute, and said backboard 110 is provided with the convex closure 111 of outside protrusion, is used to install the machine core board and the power panel of LCD.
As shown in Figure 2, Fig. 2 is the synoptic diagram of backboard 110 under assembly machine central layer 210 and power panel 220 states in the utility model LCD backlight module; Said machine core board 210 is installed in the convex closure 111 of backboard 110 with power panel 220; Said power panel 220 also can comprise the drive plate of LED in the module backlight.
As shown in Figure 2, on said backboard 110, also be provided with the trough 112 of outside protrusion; One end of said trough 112 is connected with said convex closure 111, and the other end extends to the bottom of said LCD, is used to hold the winding displacement that connects said machine core board 210 and power panel 220.
In conjunction with Fig. 2 and Fig. 3, Fig. 3 is the synoptic diagram of backboard under assembling division board 230 states in the utility model LCD backlight module.
In the present embodiment; Because adopted backboard 110 in the module backlight as the back cover of LCD; And the reflector in the module backlight is thinner usually; So contact with the reflector of metal with power panel 220 for fear of said machine core board 210, adopt a division board 230 to be arranged between said machine core board 210 and power panel 220 and the reflector.
In the LCD preferred implementation of the utility model, the oral area edge of convex closure 111 is provided with the counterbore type step 113 of adaptive division board 230 thickness, is used to install division board 230, to play the effect of supporting the location division board.
Wherein, The concrete fixed form of division board 230 can have two kinds: a kind of is to adopt PVC plate (being commonly called as wheat draws) as division board 230; Be bonded in through double faced adhesive tape in the step 113 at convex closure 111 edges; Another kind is to adopt the tinplate cover plate as division board 230, through rivet in the step 113 at convex closure 111 edges.
