Description
Technical field
The utility model relates to a kind of plane display module, particularly relates to the plane display module with single control circuit plate fixation mechanism.
Background technology
Flat-panel screens such as LCD are a kind of very common display now, compare with general cathode-ray tube display, have advantages such as low radiation, low power consumption do not take up space again, so the standard that increasing people adopts LCD to be used as desktop computer is equipped with, along with the LCD price descends fast, each big LCD manufacturer seeks the various methods that more can reduce production costs invariably, to obtain bigger profit.
The liquid crystal display membrane module of available liquid crystal display is normally controlled by being fixed on the control circuit board that back side of panel adds, and carries out data transmission by connector on the control circuit board and computer.Fig. 1 is the constitutional diagram of prior art liquid crystal display membrane module.As shown in Figure 1, on display panels 10, be welded with several fixed copper posts 11, after control circuit board 110a and 110b connect with signal connector, again with screw with control circuit board 110a and 110b spiral shell on fixed copper post 11, provide display panels 10 shows signal by control chip on control circuit board 110a and the 110b and display chip again.In addition, for the electromagnetic wave that prevents that control circuit board 110a and 110b from being produced, utilize a metal housing 120 to be fixed on the display panels 10 again with screw.But can there be difference the position of above-mentioned liquid crystal display membrane module fixed copper post 11 because of the design of each display manufacturer, this often causes liquid crystal display membrane module factory must have different membrane module stocks at different display manufacturer, makes liquid crystal display membrane module factory increase operation costs relatively.For avoiding that fixed leg 11 directly is fixed on the display panels 10, another kind of embodiment is increasing the mode of an extra fixture, fixed copper post 11 is welded on the fixture, with fixedly control circuit board 110a and 110b.Fig. 2 is another mechanism's constitutional diagram of the prosperous display module of prior art liquid.In Fig. 2, have circuit board fixture 230 lockings of fixed copper post 231 on display panels 10 with one earlier, again control circuit board 110a and 110b are locked on fixed copper post 231 and the mount pad 232, metal housing 120 engages with card ditch 233 on the circuit board fixture 230 with clamp 121 again, with the electromagnetic wave that prevents that control circuit board 110a and 110b from being produced.But this control circuit plate fixation mechanism needs two fixtures, can increase package program on the one hand, also can increase the manufacturing cost of manufacturer on the other hand.
The utility model content
The purpose of this utility model is to provide a kind of single-piece fixed mechanism, but the control circuit board simple fixation that makes the liquid crystal display membrane module is beneficial to assembling on display panels, reduce production costs simultaneously.
The purpose of this utility model is achieved in that promptly provides a kind of plane display module, comprising: a two-d display panel has an installed surface; One mask is arranged on this installed surface; And a printed circuit board (PCB), be arranged on this mask, and be electrically connected on this two-d display panel.
Wherein, aforementioned mask is the single metal plate part, and the utility model is that printed circuit board (PCB) is arranged on this mask concave side earlier, by at least one fixed part this mask is fixed on the two-d display panel again.
The advantage of the utility model device is, by above-mentioned design, can make whole liquid crystal display membrane module only need lock fixed screw when assembling and just can finish assembling, has easy accessibility, can reduce production costs again simultaneously.

Concrete implementation content
Flat-panel screens includes LCD, plasma scope etc., and below diagram is to be example with the LCD, Fig. 3 is the constitutional diagram of the utility model liquid crystal display membrane module.The fixed mechanism of control circuit board of the present utility model is a mask 320, as shown in Figure 3, the metal stamping plate that mask 320 is formed in one, when liquid crystal display mode assembly of the present utility model is assembled, control circuit board 310 need be installed in the concave side of mask 320 earlier, mask 320 is installed in display panels 10 dorsal parts, then the signal connector shade 330 of immobile liquid LCD panel 10 is finished the assembling of liquid crystal display membrane module again.Fig. 4 is the amplification stereogram that the control circuit board of the utility model liquid crystal display membrane module is installed on mask.In Fig. 3 and Fig. 4, have two first fixed part 321a on the mask 320,321b, several mount pads 322 and array support shell fragment 323, the first fixed part 321a, also are provided with a plurality of perforation 3211 on the 321b.Have a plurality of perforation 311 on the control circuit board 310, utilizing screw 312 to pass perforation 311 is fixed on control circuit board 310 on the mount pad 322 of mask 320, two first fixed part 321a of mask 320,321b then is fastened on the second fixed part 13a of display panels 10, on the 13b, and pass perforation 3211 with screw mask 320 is fixed on the display panels 10, supporting shell fragment 323 can contact with the dorsal part of display panels 10 in mask 320 fixing backs, firm support to be provided and to reach ground connection and prevent electromagnetic function.
Fig. 5 is another constitutional diagram of the utility model display module.As shown in Figure 5, signal connector shade 330 is because the position of display panels 10 signal connectors 12 is higher, and control circuit board 310 is less and the extra plate that increases of centre of gravity place institute that will be installed in display panels 10 is constructed.When the whole liquid crystal display membrane module of assembling, earlier control circuit board 310 is installed in the concave side of mask 320, again mask 320 is fixed in display panels 10 dorsal parts, ining succession couples signal connector 12 on control circuit board 310 and the display panels 10 with the soft arranging wire (not shown), and the signal connector shade 330 of display panels 10 is installed again; Fasten snap-latch piece 332 signal connector shade 330 on the grab 324 of mask 320 this moment, can stop the electromagnetic wave that signal connector 12 places by display panels 10 produce.
Fig. 6 is the stereographic map of the utility model liquid crystal display membrane module.Please refer to Fig. 6, liquid crystal display membrane module of the present utility model is with single metal stamping plate, one side is control circuit board 310 fixedly, can be used as the metal housing counterchecking electromagnetic wave of circuit board on the other hand again, make whole liquid crystal display membrane module when assembling, only need lock fixed screw and just can finish assembling, has easy accessibility, the advantage that can reduce production costs again simultaneously.In addition, the mask 320 that the utility model proposes the single metal plate part also can be applicable to the flat-panel screens that other need circuit board control, as: plasma scope, fixing circuit board and counterchecking electromagnetic wave simultaneously.
