Abstract
The utility model discloses a backlight source, including frame and the light guide plate of setting in the frame, the frame side is provided with the light emitting source towards one side of light guide plate, the play plain noodles of light guide plate is provided with the diffusion barrier, one side that the light guide plate was perhaps kept away from near the one end of light emitting source in the one side towards the light guide plate to the diffusion barrier is provided with black printing ink layer. This backlight source sets up black printing ink layer through the surface that is close to light emitting source one end at the diffusion barrier, replaces the black blackfilled compound on the former diffusion barrier, plays shading effect, and FPC extends to former black blackfilled compound's position to the light guide plate, increases FPC pastes the double faced adhesive tape on the light guide plate area, strengthens backlight source's stability.
Description
Technical field
This utility model relates to field of liquid crystal display, particularly relates to a kind of backlight。
Background technology
Along with popularizing of liquid crystal display, the requirement of the backlight illumination of liquid crystal display module is improved constantly by consumer。The quantity increasing the LED arranged on FPC in backlight is the approach of the most effective increase backlight illumination, but along with the increase of LED quantity, between adjacent LED, the area of sticking two-faced adhesive tape can reduce。The quantity of existing backlight LED light already lead to the space between adjacent LED cannot sticking two-faced adhesive tape or can only local sticking two-faced adhesive tape, and FPC lamp bar is to fix by double faced adhesive tape completely, it is the area being fixed on light guide plate sticking two-faced adhesive tape that too much LED quantity reduces FPC, and too small bonding area have impact on stability and the concordance of backlight。
Utility model content
In order to solve above-mentioned the deficiencies in the prior art, this utility model provides a kind of backlight, including framework and the light guide plate being arranged in framework, described frame sides is provided with luminous source towards the side of light guide plate, the exiting surface of described light guide plate is provided with diffusion barrier, and described diffusion barrier is provided with black ink layer near one end of luminous source in the side towards light guide plate or the side away from light guide plate。This backlight is by the diffusion barrier surface configuration black ink layer near one end of luminous source, replacing the black glue on former diffusion barrier, play shaded effect, and the space of former black glue may be used for increasing the area of FPC sticking two-faced adhesive tape, strengthens the stability of backlight。
Technical problem to be solved in the utility model is achieved by the following technical programs:
A kind of backlight, including framework and the light guide plate being arranged in framework, described frame sides is provided with luminous source towards the side of light guide plate, the exiting surface of described light guide plate is provided with diffusion barrier, and described diffusion barrier is provided with black ink layer near one end of luminous source in the side towards light guide plate or the side away from light guide plate。
In existing backlight, for preventing viewing area from producing the excessive optical phenomenon of light leak near one end of luminous source, diffusion barrier can be extended to luminous source, and the upper surface in extension pastes black glue, plays the purpose of shading。Black ink layer has extinction effect, the extinction effect of the black glue on former backlight diffusion barrier can be replaced in the diffusion barrier surface configuration black ink layer near one end of luminous source, prevent viewing area from producing the light that overflows near one end of luminous source, the very thin thickness of black ink layer, will not impact backlight thickness。
Further, described luminous source is connected to FPC, and described FPC extends on light guide plate, is fixed by sticking double faced adhesive tape。
Black ink layer is set at diffusion barrier and can reserve the space that former black glue takies, FPC and double faced adhesive tape toward the lengthening of vision area direction, increase the area of FPC and light guide plate stickup fixed double-sided glue, improve the stability of backlight lamp bar。
Further, described light guide plate is provided with reflector plate away from the side of exiting surface。
Further, described diffusion barrier is provided with bright enhancement film away from the side of light guide plate。
Further, described framework being provided with brake sack, described brake sack is black glue or black and white glue。
This utility model has the advantages that this backlight is by the diffusion barrier surface configuration black ink layer near one end of luminous source, replace the black glue on former diffusion barrier, play shaded effect, the space of former black glue may be used for increasing the area of FPC sticking two-faced adhesive tape, strengthens the stability of backlight。
Accompanying drawing explanation
The structure chart of the backlight that Fig. 1 provides for this utility model。
Detailed description of the invention
Below in conjunction with drawings and Examples, this utility model is described in detail。
As shown in Figure 1, a kind of backlight, including framework 1 and the light guide plate 2 being arranged in framework 1, described framework 1 edge surface is provided with luminous source 3 to the side of light guide plate 2, the exiting surface of described light guide plate 2 is provided with diffusion barrier 4, described diffusion barrier 4 is provided with black ink layer 6 near one end of luminous source 3 in the side (not shown) towards light guide plate 2 or the side away from light guide plate 2, described diffusion barrier 4 is disposed with upper bright enhancement film 8 away from the side of light guide plate 2, lower bright enhancement film 7, described framework 1 is provided with brake sack 9, described light guide plate 2 is provided with reflector plate 11 away from the side of exiting surface。Wherein, described brake sack 9 is black glue or black and white glue。
In existing backlight, for preventing viewing area from producing the excessive optical phenomenon of light leak near one end of luminous source 3, diffusion barrier 4 can be extended to luminous source 3, and the upper surface in extension pastes black glue, plays the purpose of shading。Black ink layer 6 has extinction effect, the extinction effect of the black glue on former backlight diffusion barrier 4 can be replaced in the diffusion barrier 4 surface configuration black ink layer 6 near one end of luminous source 3, prevent viewing area from producing the light that overflows near one end of luminous source 3, the very thin thickness of black ink layer 6, will not impact backlight thickness。
Described luminous source 3 is connected to FPC5, described FPC5 and extends on light guide plate 2, is pasted fixing by double faced adhesive tape 10。
Arranging black ink layer 6 at diffusion barrier 4 and can reserve the space that former black glue takies, FPC5 and double faced adhesive tape 10 toward the lengthening of vision area direction, increase FPC5 and light guide plate 2 paste the area of fixed double-sided glue 10, improve the stability of backlight lamp bar。
Embodiment described above only have expressed embodiment of the present utility model; it describes comparatively concrete and detailed; but therefore can not be interpreted as the restriction to this utility model the scope of the claims; in every case the technical scheme adopting the form of equivalent replacement or equivalent transformation to obtain, all should drop within protection domain of the present utility model。
