Abstract

A light guide unit is arranged aside a light source. The light guide unit includes a light guide plate and a plurality of optical configurations. The light guide unit includes a bottom face, a light-outgoing face, a light-incoming face, a side face, a first connecting face and a second connecting face. The bottom face is opposite to the light light-outgoing face. The light-incoming face, the side face, the first connecting face and the second connecting face are connected between the bottom face and the light-outgoing face, and the light-incoming face locates between the light source and the side face. The optical configurations protrude from the side face, the first connecting face and the second connecting face, and the optical configurations compose a Fresnel lens structure together. The present invention also provides a light source module.

Description

technical field [0001] The invention relates to a light guide unit and a light source module, and in particular to a light guide unit and a light source module capable of improving uneven brightness. Background technique [0002] According to different positions of the light sources, the light source modules can be mainly divided into direct-type light source modules and side-type light source modules. Compared with the direct-type light source module, the light source in the side-type light source module is generally arranged on the side of the light guide plate, so the side-type light source module can usually be made thinner, and has a wide range of applications, such as for timing-type In a naked-eye stereoscopic display device. [0003] figure 1 It is a schematic diagram of the working principle of the naked-eye stereoscopic display technology. figure 2 yes figure 1 The optical simulation results of the light source module in , where figure 2 only show figure 1 ...
