Refer to Fig. 1, in existing backlight module, most FPC (Flexible Printed Circuit, FPC) 102 fronts being attached to glue frame 106 and light guide plate 108 by FPC double faced adhesive tape 104, FPC double faced adhesive tape 104 is black and white double faced adhesive tape, and light guide plate is close to by its black flour, overflows from FPC double faced adhesive tape to prevent light, its fine flour is reflective can promote light source utilization rate, thus while effectively utilizing LED backlight 202, ensure light guide plate socket effect.But wedgewise is done at the light guide plate socket place in existing most backlight module, and FPC double faced adhesive tape 104 cannot compress light guide plate 108, causes light to overflow from FPC double faced adhesive tape 104, and then makes socket place brighter, comparatively dark between LED, bright dark inequality.
Therefore, prior art existing defects, needs to improve.
Utility model content
The purpose of this utility model is to provide a kind of backlight module improving light guide plate socket effect, effectively prevent because FPC double faced adhesive tape is fail to stick or LED floats the socket luminance nonuniformity phenomenon caused, while making full use of light source, obtain better socket effect.
The technical solution of the utility model is as follows: the utility model provides a kind of backlight module improving light guide plate socket effect, comprise: chase, be arranged at the light guide plate in described chase, to be located in described chase and the backlight that arranges of light guide plate relatively, be arranged at the reflector plate between described chase and light guide plate, to be arranged in described chase and the optical diaphragm group be positioned at above described light guide plate, the FPC being arranged at the glue frame on described chase and being connected with backlight, the back side of described glue frame is provided with a FPC mounting groove, described FPC by FPC double faced adhesive tape in the reflecting surface of sheet emitting or be affixed on chase, thus be installed in described FPC mounting groove.
Described light guide plate comprises Part I that section is wedge shape and section is the Part II of rectangle, and the position of the LED of the relative backlight of wedge shape height of described Part I is arranged.
Described glue frame is separated setting with chase, and described FPC passes through FPC double faced adhesive tape on the reflecting surface of sheet emitting.
Described glue frame and chase are wholely set, and described FPC passes through FPC double faced adhesive tape on described chase.
The described backlight module improving light guide plate socket effect also comprises a white PET film, and described white PET film is affixed on described glue frame, backlight and light guide plate outer.
Adopt such scheme, the backlight module improving light guide plate socket effect of the present utility model, on the reflecting surface utilizing FPC double faced adhesive tape FPC to be affixed on reflector plate or be directly affixed on chase, thus FPC double faced adhesive tape in prior art can be avoided cannot to compress light guide plate cause light to overflow from FPC double faced adhesive tape, cause light guide plate socket brighter, and this phenomenon comparatively dark between lamp, improve the socket effect of light guide plate, uniformity is good; Meanwhile, stick white PET film in socket position and carry out reflection ray, make full use of light source.
