Further, described pad quantity is one, and the length of described pad equals the width of described photomask.
Further, described pad is plastic material.
Further, comprise adhesive linkage between described pad and the described photomask.
Further, described adhesive linkage is bonding agent or double faced adhesive tape.
Further, described pad and described photomask are one-body molded.
The invention also discloses a kind of liquid crystal module, comprise liquid crystal display, be fitted in the polaroid of glasses for LCD base lower surface, described liquid crystal module also comprises above-mentioned backlight module.Described pad is between the flexible PCB and described photomask of described liquid crystal display.
Further, described spacer thickness is less than or equal to the thickness of described polaroid.
Further, comprise adhesive linkage between the flexible PCB of described pad and described liquid crystal display.
Further, described adhesive linkage is bonding agent or double faced adhesive tape.
The utility model discloses a kind of backlight module and liquid crystal module, upper surface by close light emitting source one end of the photomask in backlight module arranges pad, can prevent effectively that flexible PCB because of liquid crystal display is because being subject to External Force Acting, generation swing up and down or displacement excessive, and the liquid crystal display that causes breaks, phenomenon of rupture occurs.
Description of drawings

Fig. 2 is back light module unit structure schematic diagram among the utility model one embodiment;
Fig. 3 is the top view of backlight module among the utility model one embodiment;
Fig. 4 is the side view that backlight module matches with LCDs among the utility model one embodiment.
The specific embodiment
By reference to the accompanying drawings the utility model is described in further detail below by the specific embodiment
The utility model discloses a kind of backlight module, comprise light emitting source, photomask, LGP, it is characterized in that, described backlight module also comprises pad; Described pad is arranged at the photomask upper surface near on the end of light source direction.
In the present embodiment, a pad is set in backlight module, make it be placed on the photomask upper surface near on the end of light source direction, namely the flexible PCB external part of LCDs and the gap location between the photomask, when the flexible PCB that stretches out when the LCDs end is subject to external force, pad can suppress circuit board and produce excessive vibration and cause screen impaired, and set pad can be placed on the centre position of photomask end, produces preferably inhibition.
A kind of preferred version in the present embodiment, as shown in Figure 2, wherein the length of set pad 103 is identical with the width of photomask 102, so just so that any position of the flexible PCB of LCDs external part can touch the pad that backlight module arranges timely when being subject to External Force Acting, vibration and displacement that the bucking circuit plate produces because of external force, the flexible PCB external part that has effectively prevented is because of corner when stressed, and the broken angle of the screen that causes, the situation of breaking, rupturing occur.
As shown in Figure 3, preferably, oversize for the pad 108 that prevents from being arranged on photomask 102 upper surfaces, and have influence on the display effect of the luminous and liquid crystal display of backlight module, herein the width of pad should less than or equal to the length of the flexible PCB 106 that stretches out of LCDs end.Preferably, as shown in Figure 4, do not load and unload normally for the setting that guarantees pad does not affect liquid crystal module, the side of pad should not exceed photomask 102 near the light source direction side, and optimally, the side of pad is mutually concordant with the side of photomask.
More preferably, the pad in the utility model can adopt plastic material to make, prevent because of metal material to the parts injury in the liquid crystal module.
Preferably, in order to guarantee the steadiness of pad, prevent from skidding off from the flexible PCB external part of LCDs and the gap location between the photomask, can between pad and described shading evil spirit, an adhesive linkage be set, to guarantee that pad can be fixed in the gap, also played a firm effect of right flexible PCB external part simultaneously.
Preferably, it can be a kind of bonding agent that adhesive linkage can adopt, and also can be to be set to double faced adhesive tape.
In the present embodiment, pad is except bonding with photomask after the independent moulding, pad can also be one-body molded with photomask, in manufacturing process, arrange slightly thicker near the thickness of the position of light emitting source direction the photomask upper surface, with the flexible PCB external part that fills up LCDs and the gap location between the photomask, play the support of right flexible PCB external part and fixing effect.
The invention also discloses a kind of liquid crystal module, comprise liquid crystal display, be fitted in the polaroid of glasses for LCD substrate surface, and in the above-mentioned multiple backlight module embodiment any one, pad is between the flexible PCB and described photomask of described liquid crystal display.
Preferably, in the utility model, in order to guarantee whole luminous and display effect, the thickness of set pad should be less than or equal to the thickness of the polaroid that is fitted in glass baseplate surface.Optimally, the thickness of pad equals the thickness of polaroid, pad just can directly hold the flexible PCB of LCDs like this, directly the bucking circuit plate is stressed, simultaneously, can be because of thickness yet greater than polaroid so that liquid crystal display one end perk, and angulation has influence on whole luminous and display effect between LGP.
Preferably, an adhesive linkage is set between the flexible PCB of pad and LCDs, further, it can be a kind of bonding agent that adhesive linkage can adopt, and also can be to be set to double faced adhesive tape.
Preferably, also the pad in the utility model also can by the polaroid that is fitted in glass baseplate surface to the flexible PCB direction extend and form.
Above content is in conjunction with concrete embodiment further detailed description of the utility model, can not assert that implementation of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
