Liquid crystal light valve with memory |
摘要 |
Disclosed is a device and method for the storage and conversion of a light input into a corresponding output with light from another source. The device includes an improved liquid crystal light valve having as a photosensor layer a deposited memory semiconductor material which is reversibily convertible between a first stable, relatively high electrical resistance condition and a second stable, relatively low electrical resistance condition. Each change of state or condition will remain after cessation of the input until stimulated to reverse to the other state, thereby achieving a storage or memory function.
