Technical problem to be solved in the utility model is achieved by the following technical programs：

A kind of liquid crystal display module, including backlight and display floater, the backlight has pierced pattern including bottom surface Metal frame, the light guide plate with pierced pattern being arranged in the metal frame, the incidence surface and glue frame of the light guide plate it Between be provided with lamp bar；The display floater includes the TFT substrate that is oppositely arranged and CF substrates, the TFT substrate and CF substrates it Between fixed by the sealant sealing of outside and inner side, and filled with liquid crystal material, the TFT substrate and CF substrates are in hollow out figure The corresponding region of case is provided with through hole.

Further, the TFT substrate is provided with the TFT layer with pierced pattern towards on the side of the CF substrates； The CF substrates are provided with the color film layer with pierced pattern towards on the side of the TFT substrate.

Further, the CF substrates are dorsad provided with the upper polarisation with pierced pattern on the side of the TFT substrate Piece；The TFT substrate is dorsad provided with the down polaroid with pierced pattern on the side of the CF substrates.

Further, the light guide plate is provided with the reflector plate with pierced pattern away from the side of exiting surface.

Further, at least one blooming piece with pierced pattern is provided with the exiting surface of the light guide plate.

Further, the pierced pattern is circular or triangle or rectangle.

Further, pasted by the anti-dazzling screen of outside and inner side between the backlight and display floater.

Further, the fluid sealant is the epoxy glue for being mixed with silicon ball.

Further, it is provided with light shield layer on the side of the light direction of the fluid sealant.

Further, the fringe region of the TFT substrate and CF substrates in the through hole can make rounding process.

The utility model has the advantages that：The backlight and display floater of the liquid crystal display module is by relative Pierced pattern is set on the region answered, mechanical indicator can be set in pierced pattern region, make the liquid crystal display module extensive It is applied to the display terminal with mechanical indicator function such as wrist-watch, instrument.

Description of the drawings

The front view of the liquid crystal display module that Fig. 1 is provided for the utility model；

Fig. 2 is the A-A profiles of liquid crystal display module shown in Fig. 1.

Specific embodiment

The utility model is described in detail with reference to the accompanying drawings and examples.

As illustrated in fig. 1 and 2, a kind of liquid crystal display module, including backlight and display floater, the backlight includes bottom surface Metal frame 1 with pierced pattern, the light guide plate 2 with pierced pattern being arranged in the metal frame 1, the light guide plate 2 Incidence surface and glue frame between be provided with lamp bar 3；The display floater includes TFT substrate 5 and the CF substrates 4 being oppositely arranged, institute State and fixed by the sealing of fluid sealant 6 of outside and inner side between TFT substrate 5 and CF substrates 4, and filled with liquid crystal material 7, it is described TFT substrate 5 and CF substrates 4 are provided with through hole 8 on the corresponding region of pierced pattern.

The backlight and display floater of the liquid crystal display module, can be with by arranging pierced pattern on corresponding region Mechanical indicator is set in pierced pattern region, makes the liquid crystal display module be widely used in wrist-watch, instrument etc. with mechanical finger In the product of pin function.Wherein, the display floater can make through hole after completing by modes such as drilling, chemical erosions 8；The fluid sealant 6 of inner side can cross the hollow region corresponding with the pierced pattern on the backlight when making, and also may be used To cover whole pierced pattern region.

The TFT substrate 5 is provided with the TFT layer with pierced pattern, the CF bases towards on the side of the CF substrates 4 Plate 4 is provided with the color film layer with pierced pattern towards on the side of the TFT substrate 5.

The CF substrates 4 are dorsad provided with the upper polaroid 9 with pierced pattern on the side of the TFT substrate 5；It is described TFT substrate 5 is dorsad provided with the down polaroid 10 with pierced pattern on the side of the CF substrates 4.

The lamp bar 3 includes some LED and connects the FPC of some LED；The light guide plate 2 is away from exiting surface Side is provided with the reflector plate 11 with pierced pattern；At least one is provided with the exiting surface of the light guide plate 2 there is hollow out figure The blooming 12 of case, in the present embodiment, be disposed with the exiting surface of the light guide plate 2 diffusion barrier with pierced pattern, Lower bright enhancement film with pierced pattern and the upper bright enhancement film with pierced pattern, but, the quantity and type of the blooming 12 Depending on should be according to actual conditions, should not be limited with the present embodiment.

Pasted by the anti-dazzling screen 13 of outside and inner side between the backlight and display floater, the anti-dazzling screen 13 is preferred For the double faced adhesive tape that two sides is black flour.

The fluid sealant 6 is preferred but is not limited to using the epoxy glue for being mixed with silicon ball 14, and the silicon ball 14 is used to support The thickness of display floater；The TFT substrate 5 and CF substrates 4 are glass substrate.

The pierced pattern is circular or triangle or rectangle, or other any of figures, or not The figure of rule can also.
