一种长时间高稳定的LCD投影机
摘要：
本发明公开了一种长时间高稳定的LCD投影机，所述LCD投影机包括光源(1)、位于光源(1)发射方向上的红光滤光片(21)、位于红光滤光片(21)透射方向上的红光反射镜(31)、位于红光反射镜(31)反射方向上的红光LCD面板(41)、位于红光滤光片(21)反射方向上的蓝光滤光片(22)、位于蓝光滤光片(22)反射方向上的绿光LCD面板(42)、位于第二蓝光反射镜(33)的反射方向上的蓝光LCD面板(43)；所述红光LCD面板(41)、绿光LCD面板(42)和蓝光LCD面板(43)平行于光线传播的侧壁设置有温度探测器(9)，所述LCD投影机还包括微型变频空气压缩机(10)和微处理器(11)。本发明提供的LCD投影机LCD面板温度恒定，长时间使用稳定性高。
摘要（英）：

The invention discloses a long-time and high-stability LCD projector. The LCD projector comprises a light source (1), a red-light optical filter (21) located in a transmitting direction of the light source (1), a red-light reflecting mirror (31) located in a transilluminating direction of the red-light optical filter (21), a red-light LCD panel (41) located in a reflecting direction of the red-light reflecting mirror (31), a blue-light optical filter (22) located in a reflecting direction of the red-light optical filter (21), a green-light LCD panel (42) located in a reflecting direction of the blue-light optical filter (22) and a blue-light LCD panel (43) located in a reflecting direction of a second blue-light reflecting mirror (33); temperature detectors (9) are arranged on the side walls of the red-light LCD panel (41), the green-light LCD panel (42) and the blue-light LCD panel (43) parallel to light ray propagation; the LCD projector also comprises a micro variable-frequency air compressor (10) and a microprocessor (11). According to the LCD projector disclosed by the invention, the temperature of the LCD panel is constant, and the long-time stability in use is high.
