Embodiment
Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
The utility model provides a kind of anti-light leakage structure of backlight module.
Referring to figs. 1 through the structural representation that 4, Fig. 1 is backlight module in prior art; Fig. 2 is the cross section structure schematic diagram along A-A in Fig. 1; Fig. 3 is the structural representation of the installment state of the anti-light leakage structure of backlight module; Fig. 4 is the cross section structure schematic diagram along B-B in Fig. 3.The anti-light leakage structure of a kind of backlight module that the present embodiment provides, the anti-light leakage structure of this backlight module spills from the gap between glue frame 1 and chase 2 for preventing light, the front end of glue frame 1 (should be noted that, with reference to Fig. 3, the front end of glue frame 1 is the direction of the negative axle indication of Y-axis, the projecting direction of light points to negative direction by the positive dirction of Y-axis) light shielding part 3 being used for the gap between rubber cover frame 1 and chase 2 and projecting with the straight line that shuts out the light is set, the area of light shielding part 3 is more than or equal to the cross-sectional area in the gap between glue frame 1 and chase 2.
In prior art, between glue frame 1 and chase 2, there is gap, and this gap is beeline channel.Because light is rectilinear propagation, when backlight module is luminous, light will be outside to backlight module through the interstitial transmissive between glue frame 1 and chase 2, thus cause the phenomenon of light leak to occur.In order to prevent light leak, the utility model provides a kind of anti-light leakage structure of backlight module.This anti-light leakage structure mainly makes improvements in the structure of glue frame 1.
The front end of glue frame 1 is provided with light shielding part 3.Light shielding part 3 is arranged at the front end of glue frame 1, and the necessary gap between rubber cover frame 1 and chase 2 of light shielding part 3.And the area of light shielding part 3 is more than or equal to the cross-sectional area in gap.In the present embodiment, preferably, the area of light shielding part 3 is greater than the cross-sectional area in the gap between glue frame 1 and chase 2, thus avoids the error occurred in backlight module installation process, guarantees that light shielding part 3 all can gap completely between rubber cover frame 1 and chase 2 in rational alignment error.
The anti-light leakage structure of the backlight module that the utility model provides, the anti-light leakage structure of this backlight module has made improvement in the structure of glue frame 1.Particularly, arrange for the gap between rubber cover frame 1 and chase 2 with the light shielding part 3 shut out the light in the front end of glue frame 1, the area of light shielding part 3 is more than or equal to the cross-sectional area in the gap between glue frame 1 and chase 2.When the light of backlight module projects outward along the gap between glue frame 1 and chase 2 toward backlight module, light shielding part 3 has blocked light, and light is reflected in backlight module, avoids the outside of ray cast to backlight module, thus avoids product light leak.In addition, because the utility model has only done the improvement of structure on glue frame 1, thus advantage of lower cost, and the fraction defective of product also reduces greatly.
Further, light shielding part 3 is also bent to form toward the side at chase 2 place from the front end extension of glue frame 1.In order to ensure the structural stability of the anti-light leakage structure of backlight module, in the present embodiment, light shielding part 3 is extended by the front end of glue frame 1 and is bent to form.Because light shielding part 3 is connected with glue frame 1 one, therefore structural stability is better.Particularly, the front end of light shielding part 3 extends, and towards the lateral buckling at chase 2 place, bending part covers the gap between chase 2 and glue frame 1.Like this, when light is projected toward front end from the rear end of glue frame 1, can launch at light shielding part 3 place, thus avoid backlight module light leak.It should be noted that bending part must guarantee to cover the gap between chase 2 and glue frame 1 completely.
Further, the end that light shielding part 3 is connected with glue frame 1 is connecting end portion, and an end relative with connecting end portion is free end, and free end flushes with the outside of chase 2.In the present embodiment, can fully shading light line in order to ensure being extended the light shielding part 3 that is bent to form by glue frame 1 front end, preferably, the free end of light shielding part 3 flushes with the outside of chase 2.Can not only ensure that light shielding part 3 can fully shading light line like this, and make the structure of backlight module entirety cleaner and tidier.
Further, the gap between light shielding part 3 and chase 2 is that H1, H1 are more than or equal to 0.15mm, thus avoids in the process of installing at backlight module, and glue frame 1 and chase 2 interfere.
Further, the thickness of light shielding part 3 is that H2, H2 are more than or equal to 0.3mm.In this enforcement, preferably, the thickness of light shielding part 3 is greater than 0.3mm, and like this, light is just not easy to penetrate light shielding part 3, thus the phenomenon that further avoid light leak occurs.
The utility model also provides a kind of backlight module, and this backlight module comprises the anti-light leakage structure of backlight module.The structure of the anti-light leakage structure of this backlight module can refer to above-described embodiment, does not repeat them here.Naturally, the backlight module due to the present embodiment have employed the technical scheme of the anti-light leakage structure of above-mentioned backlight module, and therefore this light fixture has all beneficial effects of the anti-light leakage structure of above-mentioned backlight module.
These are only preferred embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model instructions and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
