Description
Technical field
The utility model belongs to back light model setting technology field, specifically, is related to a kind of backlight module of light leakage.
Background technique
In recent years, the flat panel display including LCD technology has obtained significant progress, gradually takes
For cathode-ray tube (CRT) display technology.For liquid crystal display, it includes liquid crystal display panel (cell) and liquid crystal surface is given
The backlight module (BackLight Unit, BLU) of plate offer light source.Backlight module generally has such as light guide plate and other optics member
Part and border structure for lightguide plate fixing and other optical elements, function are that well-off brightness and distribution are equal
Even light source can normally show image.In existing backlight module, the incident side of the light that lamp bar issues through the light guide plate, which enters, to be led
Tabula rasa, however the light that reflector plate and light guide plate edge scatter is reflected by glue frame, is led to backlight module or so side and is gone out
Easily there is light leakage phenomena in light side.
Utility model content
In order to solve the above technical problems, the purpose of this utility model is to provide a kind of backlight modules of light leakage, can have
Effect avoids three side light leakages of backlight module, guarantees product quality.
The utility model aim is achieved in that a kind of backlight module of light leakage, including backboard, lamp bar, reflector,
Light guide plate, diffusion sheet and prismatic lens, four side of backboard is upward folded and portion forms accommodating space, the accommodating in the back plate
Other three side of the lamp bar of setting on one side in space, the accommodating space is equipped with glue frame, the reflector, light guide plate, diffusion sheet
It is set gradually from the bottom up in the accommodating space with prismatic lens, key is: light guide plate described in the glue frame face
Side is equipped with inclined reflecting surface；The reflecting surface of the glue frame be arranged obliquely and with the bottom surface of backboard angle at an acute angle.It is former
Some rectangular items of glue frame, the light that reflector plate and light-guide edge scatter are reflected by glue frame, lead to backlight module or so
Easily there is light leakage phenomena in side, light emission side, and use above-mentioned reflecting surface, and reaching reflects light, is not refracted to out light
Face, to solve the phenomenon that three side light leakage of backlight module.
Preferably, the reflecting surface of above-mentioned glue frame is equipped with grey reflecting coating.Since the glue frame side of white or black is to light
When line reflection, it may appear that hickie or black patch, and the structure is used, the reflecting coating of grey is to light homogenous diffusion, even if small portion
The phenomenon that hickie or black patch will not occur in light splitter light leakage.
It in addition can also be grey, the reflecting surface gray by above-mentioned glue frame whole installation.Likewise, due to white or black
When light is reflected in the glue frame side of color, it may appear that hickie or black patch, and the structure is used, the glue frame of grey uniformly dissipates light
It penetrates, even if the phenomenon that hickie or black patch will not occur in fraction light light leakage.
Further, the top of above-mentioned glue frame is equipped with shading rubber belt, upper table of the shading rubber belt to the prismatic lens edge
Face extends and is connected thereto.There is light leakage after reflecting light in original glue frame, we using shading rubber belt attempt, but width compared with
Width causes to shield accounting reduction, and using the above structure, shading rubber belt does not need to fulfil the effect of shading, bonding effect is mainly played,
Width is also opposite to narrow, and screen accounting increases.
Further, the angle of above-mentioned reflecting surface and backboard bottom surface is α, 30 °≤α≤88 °.
Using the above structure, as long as there is certain tilt angle, there is certain effect to the reflection of light.But due to sky
Between it is limited, therefore be sent to be not easy it is too small.
Further, above-mentioned glue frame bottom is equipped with integral type rectangle interconnecting piece, and the lower end of the reflecting surface ends in the square
The ipsilateral top margin of shape interconnecting piece.Using the above structure, since reflex of the glue frame bottom to light is smaller, even if reflection, also not
It will appear light leakage, therefore glue frame bottom be arranged to rectangular block shape, to increase the contact area of bottom surface, the support for improving glue frame is steady
It is qualitative.
The utility model has the advantages that
A kind of backlight module of light leakage of the utility model, using above-mentioned reflecting surface, reaching reflects light, no
It is refracted to light-emitting surface, can effectively avoid three side light leakages of backlight module, guarantees product quality, promotes product yield efficiency, is reduced
Cost.
