Light guide plate capable of improving brightness

Abstract

The invention relates to the field of light guide plate production and processing, in particular to a light guide plate capable of improving brightness, which is characterized in that a reflecting surface is provided with a plurality of reflecting cutting grooves and a plurality of lattice points, the lattice points are distributed in an array, and the distance between the groove bottoms of two adjacent reflecting cutting grooves is equal to the distance between two adjacent rows of lattice points; in this way, when light enters the light guide plate body from the light inlet end face, due to the fact that the row of lattice points are arranged between the two reflection cutting grooves, the two reflection cutting grooves conduct the conduction direction of the light originally located on the left side and the right side of the lattice points, the angle of diffuse reflection formed by the light originally emitted to the side face of the light guide plate body is narrowed, and therefore the light guide plate body is more attractive in appearance. Light leakage from the side face of the light guide plate body can be reduced, and light loss is reduced; the lattice points comprise the light-facing surface and the backlight surface, and the two opposite ends of the light-facing surface and the backlight surface are connected, so that the light-facing surface tends to the light-emitting surface, the light energy utilization rate is improved, light emitted from the light-emitting end surface and leaked light is reduced, and the light-emitting brightness of the light guide plate body is improved.

Description

technical field [0001] The invention relates to the field of production and processing of light guide plates, in particular to a light guide plate with improved brightness. Background technique [0002] As one of the key components of the backlight, the light guide plate mainly conducts and distributes the light emitted by the light source so that the backlight forms a surface light source when emitting light. [0003] In the related art, the light-incident end surface, the light-exit end surface, the reflective surface and the light-exit surface are arranged on the light guide plate, and a plurality of hemispherical dot protrusions are arranged on the reflective surface, so that when the light enters the light guide plate from the light-incident end surface, The light will be transmitted to the reflective surface, and reflected by the dots to the light-emitting surface to form the required surface light source. [0004] In view of the above-mentioned related technologies, ...

AI Technical Summary

Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that during the transmission of light, the dots are hemispherical protrusions, so that the angle of diffuse reflection formed by the light on the reflective surface is relatively large, and there is no guidance for the light, and more light Emitted from the side of the light guide plate, resulting in easy bright edges on the side of the light guide plate and large light loss, reducing the brightness of the light output end surface
