Abstract
A liquid crystal light valve which uses the transfer of charge carriers representing a plurality of signals from a CCD array to a liquid crystal light modulated display medium. The signal charge is extracted from the back side of the CCD by driving the CCD clock voltages to zero and allowing the charge to diffuse to the back side where it is collected in a charge depleted region formed by a reverse biased diode and injected into the interface layers of a liquid crystal display medium.
