Active backplane circuitry, spatial light modulator comprising such a circuitry,and method of operating such spatial light modulator

摘要

An active semiconductor backplane for a matrix liquid crystal display comprises a plurality of mutually exclusive sets of electrically-addressable elements defining a pixel array. Scanning circuitry addresses the sets one at a time. Set selection circuitry addresses 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.
