Abstract
The utility model relates to a light guide plate technical field, in particular to light guide plate structure, including site surface course and mill flour layer constitution light guide plate body, site surface course and mill flour layer integrated into one piece, site surface course and mill flour layer go into the light mouth and be equipped with smooth prism for the diffusion angle of increase or reduction coupling point of presence surface course light, the light guide plate body with light prism integrated into one piece goes into, be equipped with the sawtooth on going into the horizontal tangent plane of light prism, set up the sawtooth and can eliminate and have bright speck and solid between the two adjacent light sources, be equipped with the utilization ratio that the concave point can improve light at the site surface course.
Description
Technical field
The utility model relates to light guide plate technical field, particularly light conducting plate structure.
Background technology
Light guide plate is the critical piece in the light source of the middle-size and small-size back side, pointolite or line source being converted into area source, can be used in the flat-panel display devices such as mobile phone, liquid crystal display, notebook computer, digital camera, for providing the area source of uniform luminance to export, make the normal show image of flat-panel screens energy.
In the prior art, when light is from multiple LED light source injection, when adjacent two LED light source spacing distances are constant, because light is through the reflection of light guide plate and refraction action, export along certain travel path in light guide plate, if when adjacent two LED light source distances are larger, blackening in light guide plate between two LED light sources is more obvious, this structure is adopted to there is following defect, very strong from the light in the light guide plate close to LED light source, light guide plate is caused to measure existing speck near LED light source, at the gap location of adjacent two LED light sources, because light is less, easily in light guide plate, form blackening.
Utility model content
The purpose of this utility model provides the light conducting plate structure avoiding light source speck and blackening to produce.
For achieving the above object, the utility model adopts following technical scheme: light conducting plate structure, comprise site surface layer and wear layer formation light conducting plate body, site surface layer and wear layer one-body molded, described site surface layer and wear layer light inlet are provided with light inlet prism, for increasing or reduce the spread angle being coupled into site surface layer light, described light conducting plate body and light inlet prism one-body molded, light inlet prism levels tangent plane is provided with sawtooth.
Described site surface layer is laid with several concave points.
Described concave point shape is one of following: circle, hexagon, triangle.
Described light inlet prism both sides are provided with chamfering.
Described sawtooth is V-shaped or triangle.
Described sawtooth acute angle is 60-90 degree.
Described sawtooth acute angle is 80 degree.
The utility model beneficial effect is: the utility model comprises site surface layer and wear layer forms light conducting plate body, site surface layer and wear layer one-body molded, described site surface layer and wear layer light inlet are provided with light inlet prism, for increasing or reduce the spread angle being coupled into site surface layer light, described light conducting plate body and light inlet prism one-body molded, light inlet prism levels tangent plane is provided with sawtooth, arrange sawtooth can eliminate between two adjacent light sources and have speck and blackening, be provided with at site surface layer the utilization factor that concave point can improve light.
accompanying drawing illustrates:
Fig. 1 is the utility model light conducting plate structure schematic diagram.
Fig. 2 is the utility model light conducting plate structure right view.
Fig. 3 is the utility model A place close-up schematic view.
Description of reference numerals:
10-light conducting plate body; 20-light inlet prism; 21-chamfering;
22-sawtooth; 30-site surface layer; 31-concave point;
embodiment:
Below in conjunction with accompanying drawing, the utility model is further described, sees accompanying drawing 1 ~ accompanying drawing 3,
Light conducting plate structure, comprise site surface layer 30 and wear layer formation light conducting plate body 10, site surface layer 30 is one-body molded with wear layer, described site surface layer 30 is provided with light inlet prism 20 with wear layer light inlet, for increasing or reduce the spread angle being coupled into site surface layer 30 light, described light conducting plate body 10 is one-body molded with light inlet prism 20, and light inlet prism 20 horizontal section is provided with sawtooth 22, arranges sawtooth 22 and can eliminate between two adjacent light sources and have speck and blackening.
In such scheme, described site surface layer 30 is laid with several concave points 31 and is provided with at site surface layer 30 utilization factor that concave point 31 can improve light.
In such scheme, described concave point 31 shape is one of following: circle, hexagon, triangle, preferred hexagon, can improve the utilization factor of light.
In such scheme, described light inlet prism 20 both sides are provided with chamfering 21, are convenient to match with glue frame.
In such scheme, described sawtooth 22 is V-shaped or triangle.
In such scheme, described sawtooth 22 acute angle is 60-90 degree, and preferred sawtooth 22 acute angle 80 degree, can disperse incident light better, improves outgoing light homogeneity.
Certainly, the above is only preferred embodiment of the present utility model, therefore all equivalences done according to structure, feature and the principle described in the utility model patent claim change or modify, and are included in the utility model patent claim.
