Liquid crystal display module major part on existing market is backlight liquid crystal display module, and it comprises housing, is located at the display panels in housing and is located at the backlight module (Backlight module) in housing.The structure of traditional display panels is by a colored filter substrate (Color Filter), a thin-film transistor array base-plate (Thin Film Transistor Array Substrate, TFT Array Substrate) and a liquid crystal layer (Liquid Crystal Layer) being disposed between two substrates form, its principle of work is to control the rotation of the liquid crystal molecule of liquid crystal layer by apply driving voltage on two sheet glass substrates, and the light refraction of backlight module is out produced to picture.Because display panels itself is not luminous, the light source that need to provide by backlight module carrys out normal show image, and therefore, backlight module becomes one of key component of liquid crystal indicator.Traditional backlight module comprises backboard, be located at backlight in backboard, be located at light guide plate in backboard, be located at light guide plate top optical diaphragm group, be located at the reflector plate between backboard and light guide plate and be located at the glue frame on backboard, the effect of described glue frame is that the elements such as lightguide plate fixing and optical diaphragm group also support display panels.
FPC (Flexible Printed Circuit, FPC), claim again flexible printed circuit board, flex circuit application, be called for short soft board, be that the one of making as base material take polyimide or mylar has height reliability, excellent pliable printed circuit, has that distribution density is high, lightweight, the feature of thin thickness.Display panels is electrically connected by FPC (FPC) and pcb board, to drive display panels to show, in driving process, can produce static, existing electrostatic prevention mode is generally, and the backboard of FPC and backlight module is electrically connected to derive static.But due to the demand of slimming, the backboard in existing many liquid crystal display modules is cancelled, this just causes static to discharge, and the quality of liquid crystal display module is caused and had a strong impact on.
Utility model content
The purpose of this utility model is to provide a kind of liquid crystal display module, and it also can effectively derive static without backboard in the situation that, effectively guarantees the quality of liquid crystal display module.
For achieving the above object, the utility model provides a kind of liquid crystal display module, comprise: backlight module and be located at the display panels on backlight module, described backlight module comprises glue frame, be located at backlight in glue frame, be located at the light guide plate in glue frame and be attached at the reflector plate of glue frame below, described display panels comprises body and installation and is electrically connected at the FPC of body, described FPC is provided with a static leading-out portion, when assembling, this static leading-out portion is connected in described reflector plate.
Described backlight module also comprises the optical diaphragm group being attached in described light guide plate.
The body of described display panels comprise TFT substrate, and the CF substrate of TFT baseplate-laminating setting and be located at TFT substrate and CF substrate between liquid crystal layer.
Described static leading-out portion is made up of tinsel.
The beneficial effects of the utility model: liquid crystal display module of the present utility model by arranging static leading-out portion on the flexible circuit board of display panels, and this static leading-out portion is connected with reflector plate, make produced static derive liquid crystal display module by FPC, in the situation that not using metal backing, also can effectively guarantee the quality of liquid crystal display module.
In order further to understand feature of the present utility model and technology contents, refer to following about detailed description of the present utility model and accompanying drawing, but accompanying drawing only provide with reference to and explanation use, be not used for the utility model to be limited.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, by embodiment of the present utility model is described in detail, will make the technical solution of the utility model and other beneficial effect apparent.
In accompanying drawing,
Fig. 1 is the perspective exploded view of the utility model liquid crystal display module;
Fig. 2 is the diagrammatic cross-section of the utility model liquid crystal display module.
Embodiment
Technological means and the effect thereof taked for further setting forth the utility model, be described in detail below in conjunction with preferred embodiment of the present utility model and accompanying drawing thereof.
Refer to Fig. 1 and Fig. 2, the utility model provides a kind of liquid crystal display module, comprise: backlight module 2 and be located at the display panels 4 on backlight module 2, described backlight module 2 comprises glue frame 22, be located at the backlight 24 in glue frame 22, be located at the light guide plate 26 in glue frame 22, be attached at the reflector plate 28 of glue frame 22 belows and be attached at the optical diaphragm group 29 in described light guide plate 26, described display panels 4 comprises body 42 and installs and be electrically connected at the FPC 44 of body 42, described FPC 44 is provided with a static leading-out portion 442, when assembling, this static leading-out portion 442 is connected in described reflector plate 28.
Wherein said glue frame 22 is used for fixing backlight 24 and light guide plate 26, due to backboard not being set, so reflector plate 28 is attached on glue frame 22 to guarantee the relative position between each element.Described static leading-out portion 442 can be made up of the good metal forming of conductive effect, preferably Copper Foil, aluminium foil.
Further, the body 42 of described display panels 4 comprise TFT substrate 422, and the CF substrate 424 that arranges of TFT substrate 422 laminating and be located at TFT substrate 422 and CF substrate 424 between liquid crystal layer (not shown), the size of described TFT substrate 422 is a bit larger tham the size of described CF substrate 424, after laminating, on TFT substrate 422, be formed with offset position 444, described FPC 44 is installed on this offset position 444, to realize the driving of the body 42 to display panels 4.When driving, control the rotation of the liquid crystal molecule of liquid crystal layer by apply driving voltage on two substrates, the light refraction of backlight module 2 is out produced to picture.
When described liquid crystal module is used, owing to applying a voltage between TFT substrate 422 and CF substrate 424, easily produce static discharge phenomenon, and the friction of the each element of liquid crystal module also can produce certain static, during due to driving, FPC 44 is electrically connected pcb board, and now by described static leading-out portion 442 being connected in to described reflector plate 28, make produced static to derive liquid crystal display module by FPC 44, static imports pcb board by FPC, finally derive from PCB ground lead, thereby make in the situation that not using metal backing, also can effectively guarantee the quality of liquid crystal display module.
In sum, liquid crystal display module of the present utility model by arranging static leading-out portion on the flexible circuit board of display panels, and this static leading-out portion is connected with reflector plate, make produced static derive liquid crystal display module by FPC, do not using under the prerequisite of metal backing, also can effectively guarantee the quality of liquid crystal display module.
The above; for the person of ordinary skill of the art; can make other various corresponding changes and distortion according to the technical solution of the utility model and technical conceive, and all these changes and distortion all should belong to the protection domain of the utility model claim.
