US08368841B2 Backlight module and liquid crystal display comprising a light guide plate with first, second, third microstructures, and a plurality of pillars 失效
背光模块和液晶显示器，包括具有第一，第二，第三微结构的导光板和多个支柱

Backlight module and liquid crystal display comprising a light guide plate with first, second, third microstructures, and a plurality of pillars
Abstract:
A backlight module includes at least one point light source and a light guide plate. The light guide plate includes a light emitting surface, a bottom surface, a light incident surface, a first side surface, a second side surface, a first microstructure, and a second microstructure. The bottom surface is opposite to the light emitting surface, the light incident surface connects the light emitting surface and the bottom surface, the point light source is disposed adjacent to the light incident surface, and the first microstructure is formed on the light incident surface. The first side surface is opposite to the light incident surface and connects the light emitting surface and the bottom surface, and the second side surface connects the light emitting surface, the bottom surface, the light incident surface, and the first side surface. The second microstructure is formed on the second side surface.
Abstract(Chinese):

背光模块包括至少一个点光源和导光板。 导光板包括发光表面，底表面，光入射表面，第一侧表面，第二侧表面，第一微结构和第二微结构。 底面与发光面相反，光入射面连接发光面和底面，点光源与光入射面相邻配置，第一微结构形成在光入射面上。 第一侧表面与光入射表面相对，并且连接发光表面和底表面，第二侧表面连接发光表面，底表面，光入射表面和第一侧表面。 第二微结构形成在第二侧表面上。
