Abstract
Using the amorphous silicon (a-Si:H) film, which is cheap and has a small lag, as the photoconductive layer of the liquid crystal light valve (LCLV) is an ideal selection. With the method of impedance matching, we have designed and fabricated an a-Si:H LCLV and have obtained a clear image on a large screen projection system. The resolution of the valve was 20 lp/mm. The sensitometry measurement showed that the projection light level varies linearly with the writing light level when the latter is below 100 (mu) W/cm2. The measurement of the transient response at the writing light level of 100 (mu) W/cm2 indicated that the rise time and the decay time were 60 ms and 80 ms, respectively.
