    • A projector is provided, which includes a red substrate, a green substrate, a blue substrate, an X-cube, an electronic control element, a light guide element, a light valve element, and a projection lens. The red substrate, the green substrate, and the blue substrate respectively illuminate three surfaces of the X-cube, and the light is mixed in the X-cube and then exits from a light emitting surface. The electronic control element controls the red substrate, the green substrate, and the blue substrate. The light guide element is used for reflecting the light from the light emitting surface of the X-cube. The light valve element is used for reflecting the light from the light guide element back to the light guide element, and the light passes through the light guide element and then projected by the projection lens onto a projection plane area. Thereby, the ON/OFF switch time of the present invention is shortened, the temperature may not get over high, the optical efficiency is enhanced, and the whole volume is significantly reduced.
    • 提供一种投影仪,其包括红色基板,绿色基板,蓝色基板,X形立方体,电子控制元件,导光元件,光阀元件和投影透镜。 红色衬底,绿色衬底和蓝色衬底分别照射X形立方体的三个表面,并且将光在X立方体中混合,然后从发光表面离开。 电子控制元件控制红色衬底,绿色衬底和蓝色衬底。 导光元件用于反射来自X形立方体的发光表面的光。 光阀元件用于将来自导光元件的光反射回导光元件,并且光通过导光元件,然后由投影透镜投影到投影平面区域上。 因此,本发明的ON / OFF开关时间缩短,温度可能不会变高,光效率提高,整体体积显着降低。
