    • A light guide plate adapted to guide a beam emitted from at least one light emitting device and including a light transmissive substrate and a plurality of optical structures is provided. The light transmissive substrate has a light emitting surface, a bottom surface opposite to the light emitting surface, and a light incident surface connecting the light emitting surface and the bottom surface. The beam from the light emitting device enters the light transmissive substrate through the light incident surface and is emitted out. The optical structures are disposed on the bottom surface and each of the optical structures has a first total internal reflection (TIR) surface and a second TIR surface. A part of the beam from the light incident surface is totally internally reflected by the first TIR surface and the second TIR surface in sequence. A backlight module using the light guide plate is also provided.
    • 提供一种适于引导从至少一个发光装置发射的光束并包括透光基板和多个光学结构的导光板。 透光性基板具有发光面,与发光面相反的底面以及连接发光面和底面的光入射面。 来自发光装置的光束通过光入射面进入透光性基板并被射出。 光学结构设置在底表面上,并且每个光学结构具有第一全内反射(TIR)表面和第二TIR表面。 来自光入射表面的光束的一部分由第一TIR表面和第二TIR表面依次内部反射。 还提供了使用导光板的背光模块。

    • An illumination device and an image display apparatus using the same. The illumination device comprising a light source, an illumination uniformizing device, and a polarization converter. The image display apparatus comprises an illumination device provided in the invention, a synthesizing means, and a projection means. The illumination uniformizing device has an incident plane for receiving a light emitted from the light source. Opposite the incident plane, a mirror is used as a side plane of the illumination uniformizing device to reflect the light coming from the incident plane. A bottom plane at a lower side and projection plane at an upper side of the incident plane are disposed between the incident plane and the side plane. A scattering pattern gradually condensed from the incident side toward the side plane is formed on the bottom plane, so that the light incident from the incident plane is made uniform.
    • 照明装置和使用其的图像显示装置。 所述照明装置包括光源,照明均匀化装置和偏振转换器。 图像显示装置包括本发明提供的照明装置,合成装置和投影装置。照明均匀装置具有用于接收从光源发出的光的入射面。 与入射面相对,使用反射镜作为照明均匀化装置的侧面,以反射来自入射面的光。 下侧的底面和入射面的上侧的投影面配置在入射面和侧面之间。 在底面上形成从入射侧向侧面逐渐冷凝的散射图案,使从入射面入射的光均匀。
