Above-mentioned existing LCD needs earlier circuit board to be fixed in the fixed mount 30 when assembling, LCD module 20 is embedded into fixed mount 30 inside again, and the screw of the LCD module of aliging then 20 sides and the screw 31 of fixed mount side are screwed then.This assemble method need the screw of artificial alignment both sides, but screw is arranged on two sides of fixed mount, therefore need be around behind the side alignment and the screw of screwing on, around repeating to opposite side once to align and the work of stubborn screw, waste time and energy.

In addition, more and more pursue nowadays lightening, the structural limitations of fixed mount the trend of this technical development, demand urgently improving.

The utility model content

The purpose of this utility model provides a kind of LCD, overcomes existing LCD assembling trouble, and is unfavorable for lightening defective, makes assembling convenient succinct, and can reduce volume.

For achieving the above object, the utility model provides a kind of LCD, comprise preceding frame, LCD module in the former frame is set, and with the suitable after-frame of preceding frame, LCD also comprises fixed mount, one side of described fixed mount is fixed on the back of described LCD module, opposite side is fixed on the after-frame, and the size of described fixed mount is provided with circuit board less than described LCD module in the described fixed mount.

As shown from the above technical solution, the utlity model has following beneficial effect:

1, LCD of the present utility model, by the fixed mount littler than LCD module being located at the back of LCD module, and can adjust fixed mount according to the size of circuit board, the fixed mount on the existing LCD of being set in module is compared, reduce volume, be beneficial to lightening development trend.

2, LCD of the present utility model is by being located at screw at the back of LCD module, when making assembling, the workman only needs operate at the back and get final product, avoided in the prior art, about the alignment trouble of the turn of the screw also back and forth, make assembling convenient succinct, saved built-up time.

Embodiment

Below by drawings and Examples, the technical solution of the utility model is described in further detail.

Fig. 2 is the STRUCTURE DECOMPOSITION stereographic map of the utility model LCD.As shown in Figure 2, frame 10, LCD module 20, fixed mount 30 and after-frame 40 before LCD of the present utility model comprises.Preceding frame 10 is suitable with after-frame 40, fixes on the frame 10 before after-frame 40 is sheathed on.LCD module 20 is embedded in the former frame 10.Fixed mount 30 1 sides are fixed on the back 200 of LCD module 20, and opposite side is fixed on the after-frame 40, and the size of fixed mount 30 is less than described LCD module 20.The inside of fixed mount 30 is provided with circuit board 50, can adjust fixed mount 30 according to the size of circuit board 50.

LCD of the present utility model, by the fixed mount littler than LCD module being arranged on the back of LCD module, and can adjust fixed mount according to the size of circuit board, the fixed mount on the existing LCD of being set in module is compared, reduce volume, be beneficial to lightening development trend.

Fig. 3 is the synoptic diagram of first embodiment of assembling fixed mount and LCD module.As shown in Figure 3, LCD module 20 comprises assemblies such as Polarizer (not shown), liquid crystal panel (not shown) and module backlight, and module wherein backlight comprises backboard (Back Cover) 21, reflectance coating 22, light guide plate 23 and optical thin film 24.Its dorsulum 21 is positioned at the back 200 of module backlight, and backboard 21 is provided with a plurality of protruding 210, and described protruding 210 are provided with first screw 211.
