Description

Novel light guide plate structure

Technical Field

The utility model relates to the technical field of light guide plate structures, in particular to a novel light guide plate structure.

Background

The light guide plate (light guide plate) is made of optical acrylic/PC plate, and then high-tech material with high refractive index and no light absorption is used to print light guide points on the bottom surface of the optical acrylic plate by laser engraving, V-shaped cross grid engraving and UV screen printing technology. The optical-grade acrylic sheet is used for absorbing the light emitted from the lamp to stay on the surface of the optical-grade acrylic sheet, when the light irradiates each light guide point, the reflected light can be diffused towards each angle, and then the reflected light is damaged and is emitted from the front surface of the light guide plate. The light guide plate can uniformly emit light through various light guide points with different densities and sizes. The reflecting sheet is used for reflecting the light exposed from the bottom surface back to the light guide plate to improve the utilization efficiency of the light, and under the condition of the same area light-emitting brightness, the light-emitting efficiency is high and the power consumption is low. The single-sided microstructure array light guide plate is generally manufactured by an extrusion molding process.

The light guide plate all develops toward frivolous direction on the market at present, so a lot of super narrow frame machine types appear, lead to the light guide plate to leave white by the limit to reduce, and the convex structure reflection ray of the fixed membrane material of light guide plate mirror surface arouses the problem of poor picture.

Therefore, the novel light guide plate structure is provided, aiming at improving the defect of poor backlight effect caused by the bright spots and bright lines of the backlight light emitting surface, and improving the defect of poor backlight light emitting surface by adding the microstructures on the boss of the light guide plate.
