Circuit for active rear wall, a spatial light modulator with such a circuit and method for operation of such a spatial light modulator

摘要

An active semiconductor backplane (3) for a matrix liquid crystal display comprises a plurality of mutually exclusive sets of electrically addressable elements defining a pixel array (4), means (44) arranged to address the sets one at a time, and means (44, 45) for addressing more than one of the plurality of sets simultaneously. Preferably the sets are simultaneously addressable rows, for fast blanking. Single pass and two-pass schemes for writing and re-writing the array are described.
