Description
Technical field
The utility model relates to LCD backlight source field, particularly relates to a kind of light guide board microstructure.
Background technology
Backlight (BackLight) is positioned at liquid crystal display (LCD) a kind of light source behind, and its illumination effect will directly have influence on LCD MODULE (LCM) visual effect.Liquid crystal display itself is not luminous, and its display graphics or character are the results that it is modulated light.Hotspot problem is the ubiquitous problem of backlight, how to weaken and to eliminate this problem, is the technical barrier that this area faces for a long time.
Utility model content
The purpose of this utility model is to provide a kind of light guide board microstructure, to solve the problems of the technologies described above.Microstructure is prism structure, has the effect gathering light, can improve the hotspot problem produced because light intensity between LED light road is more weak.
Technical problem to be solved in the utility model realizes by the following technical solutions:
A kind of light guide board microstructure, it is characterized in that: it is characterized in that: comprise light guide plate and be arranged on the microstructure in light guide plate, also comprise the LED illuminator being arranged on light guide plate one end, described microstructure is arranged on the exiting surface of light guide plate light in part, and corresponding with the position between adjacent two LED illuminator.
Described microstructure is prism structure, is made up of continuous print many corner angle, and the corner angle are wherein higher than the corner angle on both sides, and the corner angle on both sides are symmetrical centered by the corner angle of centre.
Described microstructure is the prism structure of band fillet, and be made up of continuous print many ribs, the upper surface of rib is circular arc, and the rib is wherein higher than the rib on both sides, and the rib on both sides is symmetrical centered by the rib of centre.
The beneficial effects of the utility model are:
Light guide board microstructure of the present utility model, this microstructure is arranged on the exiting surface of light guide plate light in part, and corresponding with the position between LED light road, utilizes this microstructure can improve the brightness in this region, reaches the effect improving hotspot problem.
Accompanying drawing explanation
