Abstract :
A-Si:H-based liquid crystal light valve (LCLV) is described in this brief. This LCLV employs cadmium telluride (CdTe) and Vanadyl phthalocyanine (VOPc) multiple absorption layers. The multiple absorption layers have high absorption ability in the visible and near-infrared range, which ensures the LCLV to have a high sensitivity and high reading to writing light isolation ratio. Therefore the LCLV with CdTe and VOPc multiple absorption layers has a higher performance compared with a valve with only a CdTe absorption layer. The LCLV has a peak response at the wavelength of 700 nm and is suitable for projection displays.
