Abstract
The utility model provides a light-emitting diode (LED) backlight module capable of preventing light leak, which comprises a light guide plate, a light source arranged on one side of the light guide plate and an outer frame tightly sleeved with the light guide plate. A light guide plate clamping groove is arranged at the outer edge of the light guide plate, an outer frame clamping position matched with the light guide plate clamping groove is arranged on the inner wall of the outer frame, the light guide plate clamping groove inwards recesses at the outer edge of the light guide plate, and the outer frame clamping position corresponding to the light guide plate clamping groove outwards protrudes out of the inner wall of the outer frame. By means of the improvement on a light guide plate structure in the LED backlight module, light leak is avoided, visual effect taste of an LED liquid crystal module is improved, performance of a liquid crystal television is optimized, and the LED backlight module capable of preventing the light leak is simple in process operation, high in feasibility and excellent in popularization, thereby improving competitiveness of products.
Description
Technical field
The utility model relates to the LED display field, relates in particular to a kind of anti-light leak LED-backlit module.
Background technology
Along with China LED LCD TV demand sharply rises violently; The development of LED-backlit module field is swift and violent, considers that from the angle in market narrow frame design of backlight module is irresistible; This moment, LGP and glass visible area distance was also more and more littler, also manifested gradually apart from Minimum Area light leak problem backlight.
Existing, through increase LGP side and glass visible area apart from solve problem, but this kind mode has than limitations on narrow frame designs, and can not eliminate the light leak problem fully.
The utility model content
The purpose of the utility model is to provide a kind of anti-light leak LED-backlit module, to solve LED-backlit module light leak problem.
The purpose of the utility model realizes through following technical scheme.
A kind of anti-light leak LED-backlit module comprises LGP, is arranged on the light source of said LGP one side, and with the housing of the tight socket of said LGP; The outward flange of said LGP is provided with the LGP draw-in groove; The inwall of said housing is provided with the housing screens that matches with said LGP draw-in groove; Said LGP draw-in groove indent is in the outward flange of said LGP, with the corresponding housing screens of this LGP draw-in groove evagination in the inwall of said housing.
Preferably, the side of said LGP draw-in groove is pasted with reflector plate or black belt.
Preferably, said reflector plate or black belt institute region covered is less than the thickness of said LGP draw-in groove.
Preferably, said housing is the elastoplast structure.
Preferably, said light source is formed at least two light emitting diodes.
The utility model compared with prior art, the utility model is avoided the appearance of light leak problem through light conducting plate structure in the LED-backlit module is improved; Thereby promote looking of LED liquid crystal module and imitate taste; Optimize the LCD TV performance, and technological operation is simple, feasibility is high; Popularization is good, has therefore promoted competitiveness of product.
Description of drawings
Fig. 1 is the utility model LED-backlit modular structure sketch map.
The specific 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 LED-backlit modular structure comprises: a LGP 10, be arranged on the light source (not shown) of said LGP 10 1 sides, and the housing 30 that engage sleeves is connected to said LGP 10 is formed.Be symmetrically distributed with 4 LGP draw-in grooves 11 in the left and right sides of LGP 10, said LGP draw-in groove 11 is shaped as the rectangle of indent in said LGP 10 edges; The inwall of said housing 30 is provided with housing screens 31 and cooperatively interacts with said LGP draw-in groove 11 and closely connect together, and the shape size adapts with said LGP draw-in groove 11.
In the utility model, for further solving issuable light leak problem, be pasted with reflector plate or black belt in the side of LGP draw-in groove 11, the attaching width is a/n, and wherein, n=2,3,4..., a are the thickness of LGP draw-in groove 11.
Said housing 30 is processed by having better flexible plastics; Said light source is formed at least two light emitting diodes.
The utility model is avoided the appearance of light leak problem through light conducting plate structure in the LED-backlit module is improved, and imitates taste thereby promote looking of LED liquid crystal module; Optimize the LCD TV performance, and technological operation is simple, feasibility is high; Popularization is good, has therefore promoted competitiveness of product.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection domain of the utility model.
