摘要： An optical erasable liquid crystal disc memory system is provided which includes a rotating liquid crystal information storage medium confined by two surfaces. Various thin films on the surfaces are used to establish the proper conditions within the liquid crystal medium which, in combination with incident radition and applied voltages, accomplish the read, write, and erase functions.The resulting system provides a locally erasable optical disc memory with high density storage, long-term information stability under a wide range of temperature, and read, write, and erase times compatible with modern high speed computers.

摘要： An active matrix liquid crystal light valve is disclosed. The addressing matrix has an array of electrodes to create electric fields across the liquid crystal layer. The light valve has a continuous nonconductive reflector layer, separate and distinct from the electrode array of the active matrix. This light valve has a leveling layer disposed on the active matrix to form a planar surface. The reflector layer is formed as a continuous sheet on the planar surface of the leveling layer. An additional invention is the use of fringing fields to switch substantially all of the liquid crystal, including areas not directly over the electrodes.

摘要： A hard copy such as a printed wiring board is fabricated by exposing to radiation a liquid crystal cell in which a desired pattern is written and directing the pattern-carrying radiation projected from the cell by transmission or reflection to a substrate which is coated with a material sensitive to the radiation and disposed alignedly at an exposure position by optical registration. The duration of the exposure is controlled for a given light intensity and for the type of the coating material. A pattern may be written in one cell substantially simultaneously as another cell is used for the projection imaging. After a produced pattern is compared with a reference pattern, corrections may be effected through a processor which controls the writing of a pattern in a cell.
