Abstract
The utility model discloses a liquid crystal display backlight module, which comprises a plastic frame and a reflective film which is attached to the plastic frame through a double-sided adhesive tape, wherein one side of the plastic frame is downwards recessed at a position where the reflective film is attached, so that a first groove used for containing the reflective film is formed; the first groove is downwards recessed at a position where the double-sided adhesive tape is attached between the reflective film and the plastic frame, so that a second groove is formed; and the second groove has the depth which is consistent with the thickness of the double-sided adhesive tape and is used for containing the double-sided adhesive tape. Therefore, the thickness of the double-sided adhesive tape can be eliminated, the thickness of the backlight module is not increased, and the thickness of a light guide plate is not reduced.
Description
Technical field
The utility model relates to field of liquid crystal display, particularly relates to the backlight liquid crystal display module.
Background technology
LCD (LCD) is widely used in the display technique field; The demonstration of liquid crystal normally forms the function that the liquid crystal of electric field driven between electro-conductive glass realized demonstration through two electro-conductive glass; But liquid crystal itself can not be luminous; Therefore need really realize Presentation Function by external light source, the backlight of main flow has LED-backlit source and TTF backlight at present.
In the backlight liquid crystal display module, reflective membrane normally pastes through double faced adhesive tape and carries out reflection action on the plastic cement frame.Usually the thickness of double faced adhesive tape is selected 0.05-0.10mm; This thickness can go to eliminate through two approach; One is exactly the thickness that increases module backlight, and this and LCD more and more are tending towards gently, thin design is disagreed, and the 2nd, eliminate through reducing the light guide plate size; And the light guide plate size generates the injection moulding condition restriction that a limit is arranged, and can not arbitrarily deduct thickness.
The utility model content
The purpose of the utility model is to overcome the deficiency of present technology, and a kind of LCD backlight module is provided, and it can eliminate the thickness of double faced adhesive tape, and can not increase the thickness of module backlight, does not also reduce the thickness of LGP.
For realizing above-mentioned purpose, the technical scheme that the utility model adopted is:
A kind of LCD backlight module; Comprise a plastic cement frame and stick on the reflective membrane on the plastic cement frame through double faced adhesive tape; Said plastic cement frame one side down be recessed to form in the position of pasting reflective membrane one be used for ccontaining reflective membrane first groove; Said first groove posts double faced adhesive tape between reflective membrane and plastic cement frame position down is recessed to form one second groove again, and second depth of groove and double faced adhesive tape consistency of thickness are used to hold double faced adhesive tape.
The beneficial effect of the utility model is: lower recess second groove that forms a degree of depth and double faced adhesive tape consistency of thickness is used for holding double faced adhesive tape again in holding first groove of reflective membrane; So; Can eliminate the thickness of double faced adhesive tape; And do not increase the thickness of module backlight, do not reduce the thickness of LGP yet.
Description of drawings
Fig. 1 is the synoptic diagram of this practical LCD backlight module.
Embodiment
For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
As shown in Figure 1; The utility model LCD backlight module comprises a plastic cement frame 1 and sticks on reflective membrane on the plastic cement frame 1 (figure does not show) through double faced adhesive tape, said plastic cement frame 1 one sides down be recessed to form in the position of pasting reflective membrane one be used for ccontaining reflective membrane first groove 2.
In the present embodiment, preferably, said first groove 2 posts double faced adhesive tape between reflective membrane and plastic cement frame 1 position down is recessed to form one second groove 3, the second grooves, 3 degree of depth and double faced adhesive tape consistency of thickness again, is used to hold double faced adhesive tape.
In sum; Lower recess second groove 3 that forms a degree of depth and double faced adhesive tape consistency of thickness is used for holding double faced adhesive tape again in holding first groove 2 of reflective membrane, so, can eliminate the thickness of double faced adhesive tape; And do not increase the thickness of module backlight, do not reduce the thickness of LGP yet.
