恢复液晶投影机亮度的方法探讨

Methods of restoration of luminance of LCD projector

液晶投影机亮度降低后用一般方法不能恢复时,多为偏振光转换器损坏所致,由于PCS缺乏或价格高等原因,用户会选择不做修理,从而造成设备不必要的闲置或报废。对此做了深入的探讨,介绍了易实施、成本较低的解决方法。

When luminance of LCD projector declines and it is impossible to restore its brightness by using the common methods,it is very likely that the polarization conversion system is damaged.Due to the shortage of PCS or the high price of the PCS,users will choose not to have it repaired.As a result,the LCD projector is put aside and even scrapped.In this paper,the author discusses a simple,low cost method to resolve this problem after a deep analysis.
