Description
Technical field
The utility model relates to a kind of light guide plates for liquid crystal display.
Background technique
Light guide plate is the significant components in LCD backlight mould group, design with manufacture be backlight module key technology it
One.Light guide plate major function is guidance radiation direction, controls the uniformity of brightness, performance directly determines guide-lighting mould group
Performance.And light guide plate surface micro-structure and the angle to backlight module beam projecting, determine the uniformity of beam projecting.
Widely used guide-lighting plate shape is mostly rectangle in the market, and the light guide plate of the structure, light guide plate effect is undesirable, liquid
Crystal display brightness value is not high.
Summary of the invention
The utility model proposes a kind of light guide plates for liquid crystal display.
It is a kind of light guide plate for liquid crystal display that the utility model, which solves scheme used by technical problem, including
Light conducting plate body, the light-emitting surface on the upside of light conducting plate body are disposed with transition, guide-lighting slot by dipped beam source to distance light source
Portion, transition are plane, and guide-lighting groove portion includes longitudinally spaced uniformly distributed several V-grooves, and V-groove is transversely arranged, V-groove
Groove depth is gradually increased by dipped beam source to distance light source.
Further, V-groove is 2-6mm at a distance from dipped beam source.
Further, the distance between adjacent V-groove is 25-45 μm.
Further, the width of V-groove is 0.8-0.9 times of the distance between adjacent V-groove.
Further, excessive fillet is arranged in the slot bottom of V-groove.
Further, the size of excessive fillet is R10-R20 μm.
Further, the angle of V-groove two sides is 90 ° -100 °.
Compared with prior art, the utility model has the following beneficial effects: structure is simple, design rationally, can effectively increase
The brightness of liquid feeding crystal display.
Detailed description of the invention
The utility model patent is further illustrated with reference to the accompanying drawing.
Fig. 1 is the structural schematic diagram one of the utility model；
Fig. 2 is the structural schematic diagram two of the utility model.
In figure:
1-LED light source；2- light conducting plate body；3-V type groove；4- transition.
Specific embodiment
The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
As shown in Figs. 1-2, a kind of light guide plate for liquid crystal display, including light conducting plate body, light conducting plate body upside
Light-emitting surface transition, guide-lighting groove portion are disposed with by dipped beam source to distance light source, transition is plane, and transition can prevent
Only LED light eye phenomenon, guide-lighting groove portion include longitudinally spaced uniformly distributed several V-grooves, and V-groove is transversely arranged, the slot of V-groove
It is deep to be gradually increased by dipped beam source to distance light source.
In the present embodiment, V-groove is 2-6mm at a distance from dipped beam source,
In the present embodiment, the distance between adjacent V-groove be 25-45 μm, the distance be V-groove one side with it is adjacent
The distance between the ipsilateral of adjacent V-groove.
In the present embodiment, the width of V-groove is 0.8-0.9 times of the distance between adjacent V-groove.
In the present embodiment, excessive fillet is arranged in the slot bottom of V-groove.
In the present embodiment, the size of excessive fillet is R10-R20 μm.
In the present embodiment, the angle of V-groove two sides is 90 ° -100 °.
Above-listed preferred embodiment has been further described the purpose of this utility model, technical solution and advantage,
It should be understood that the above is only the preferred embodiment of the utility model only, it is not intended to limit the utility model, it is all
Within the spirit and principles of the present invention, any modification, equivalent replacement, improvement and so on should be included in practical
Within novel protection scope.
