Title: Liquid crystal light valve
Inventor: TSUNODA ICHIRO
IPC: G09G3/36
Filed: 1987-06-19
Abstract: PURPOSE:To widen the range of liquid crystal material selection and to eliminate the need for a long time at the time of its writing by supplying a signal to picture element electrodes constituting picture elements through optical switch elements which operate with infrared light respectively. CONSTITUTION:This is a liquid crystal light valve used for a projection type display device formed by charging liquid crystal between a couple of substrates which have parallel and opposite electrodes at necessary intervals, and the signal is supplied to the picture element electrodes which constitute the respective picture elements through the switch elements operating with infrared light. Namely, phototransistors 7 are formed of PbS, PbSe, InAs, etc., having large photoelectric effect in the infrared range and when the phototransistors 7 are irradiated with the light, the phototransistors 7 conduct to supply the signal for display to the picture element electrodes 5. Consequently, liquid crystal which changes in molecule array with an electric field is usable without being limited to liquid crystal whose liquid crystal material usable for the liquid crystal light valve can shift in phase, thereby shortening the writing time.
