Description
Technical field
The utility model is related to a kind of light guide plate more particularly to a kind of light guide plates of multi-section display.
Background technology
Liquid crystal display device has many advantages, such as that light, thin, power consumption is small, is widely used in modernizing in information equipment.Due to liquid
Liquid crystal in LCD panel does not have the characteristics of luminescence in itself, to reach display effect, it is necessary to provide one side to liquid crystal display panel
Light supply apparatus, such as backlight module, the function of the planar light source device be to provide briliancy fully to liquid crystal display panel and uniformly it
Area source.For LED light source, during due to LED light extractions tool there are one the energy at the limited angle of divergence and light extraction is larger, so
When light guide plate is lighted by LED, it can see apparent bright dim phenomenon in the light inlet of light guide plate, be the Hot Spot being commonly called as,
So the quality of LED light inlets can be caused bad after light guide plate covers glass.
The principle of light guide plate is to destroy the complete of LED light source light using site (ink site, hot pressing site are molded site)
Reflection so as to which light be allowed to be come out from light guide plate, realizes that LED line light source becomes the purpose of area source, light emitting source is provided for display.
But existing light guide plate mesh point is simple, and light-emitting surface is without any processing, light utilization is low, some light-emitting surfaces process just
It is common shape, triangle is circular, but the optics of both shapes promotes effect unobvious.
However existing light guide plate is since display requirement picture is uniform, so its light guide plate glazed thread is all in a kind of bright dark
Degree display, for some special industries, it is necessary to which display divides different zones to show different pictures, and the bright darkness of different zones
Also requirement is different, this allows for having subregion setting on light guide plate, it can be seen that existing light guide plate can not realize subregion
Display, it would be highly desirable to which a kind of light guide plate goes to solve the problems, such as this.
Utility model content
The purpose of the utility model is to overcome a kind of light guide plate of multi-section display the defects of the prior art, is provided, pass through
