    • A high efficiency light combination module of projection system includes a cubic polarizing beam splitter prism serving as a main body around which four lens arrays, three retarders, and three optical plates are arranged, which is used in combination with coatings that enables transmission or reflection of specific lights to allow different color lights incident from different directions to be combined as a single illumination light beam and to allow the single illumination light beam so combined to be uniform by the lens arrays to facilitate light collection and projection by a panel and a projection lens arranged behind. A polarization conversion film is set at light outgoing port to transfer the polarization states of the combined single illumination light beam into a specific polarized light for a liquid crystal projection system.

    • An optical projection system can receive a red light beam, green light beam, and blue light beam. The optical projection system includes a color-combination prism, and the light beams respectively enter the color-combination prism from three surfaces and are combined into a mixed light beam, which exits from another surface. A projection lens set receives the mixed light beam to perform the projection. Each of the light beams further includes a liquid crystal reflection panel and a wire grid polarizer (WGP). The liquid crystal reflection panel is parallel to the corresponding surfaces of the color-combination prism. In the design, before the light beam entering the color-combination prism, they are first reflected by the WGP onto the liquid crystal reflection panel, and the liquid crystal reflection panels respectively with a polarizing state reflect the light beams, passing through the WGP and directly propagating toward the color-combination prism.
    • 光学投影系统可以接收红色光束,绿色光束和蓝色光束。 光学投影系统包括颜色组合棱镜,并且光束分别从三个表面进入组合棱镜,并且组合成从另一表面离开的混合光束。 投影透镜组接收混合光束以执行投影。 每个光束还包括液晶反射板和线栅偏振器(WGP)。 液晶反射面板与彩色组合棱镜的相应表面平行。 在设计中,在光束进入组合棱镜之前,它们首先被WGP反射到液晶反射面板上,分别具有偏光状态的液晶反射板反射穿过WGP的光束, 直接向彩色组合棱镜传播。

    • The invention relates to a liquid crystal display projector with a lens protecting device capable of protecting and positioning lens of liquid crystal display projector. The lens protecting device of the invention comprises a cover, a top housing, a bottom housing, an actuating device, a plurality of springs and a mirror, where the lens is secured in the top housing and the actuating device also is connected to the top housing. Moreover, the mirror is located in the cover, and the top housing and the bottom housing are connected to each other by said springs. Further, the cover can be connected to the top housing or the projector with at least one hinge and projection of the projector is adjusted by only rotating the cover around the hinge. When the top housing is gradually covered by the cover, the actuating device will touch the top housing and deform these springs such that the top housing is located into the LCD projector and the lens is located in the protecting position. Therefore, When the LCD projector does not be operated, the lens is covered by the cover and disadvantages such as dirty and scare are properly protected. On the other hand, when the LCD projector is operating, lens is positioned to the projecting position by these springs.
    • 本发明涉及具有能够保护和定位液晶显示投影仪的透镜的透镜保护装置的液晶显示投影仪。 本发明的镜头保护装置包括一个盖子,一个顶部壳体,一个底部壳体,一个致动装置,多个弹簧和一个镜子,其中透镜固定在顶部壳体中,并且致动装置也连接到顶部 住房。 此外,镜子位于盖子中,顶部壳体和底部壳体通过所述弹簧相互连接。 此外,盖可以通过仅使铰链旋转盖来调节投影机的至少一个铰链和投影来连接到顶部壳体或投影仪。 当顶部壳体被盖子逐渐覆盖时,致动装置将接触顶部壳体并使这些弹簧变形,使得顶部壳体位于LCD投影仪中并且镜头位于保护位置。 因此,当液晶投影机未被操作时,镜头被盖子覆盖,并且诸如肮脏和恐慌等缺陷得到适当的保护。 另一方面,当LCD投影机正在工作时,透镜通过这些弹簧定位在突出位置。
