Current modulation method for a liquid crystal display projection lamp

摘要

Method A method for reducing artifacts in color sequential LCD projection system, to provide a stable lamp operation without flicker. The method comprises the step of establishing the frequency of the pulsed light at an arbitrary rate according to the display frame rate. Is achieved by being replaced by a sequence of low lamp current levels in successive frames in order to improve further, minimizing the spatial modulation, a sequence of intervals of brightness is improved.
