COLOR NON-UNIFORMITY ALIGNMENT FOR LIGHT ENGINES

摘要

A system of color non-uniformity alignment for a liquid crystal display (290), includes light measuring equipment (292 and 294) for measuring correction information at a plurality of plane points on the liquid crystal display and memory (250) for storing the correction information, a plurality of matrix memories (205, 275 and 245) utilizing the correction information, a plurality of horizontal and vertical interpolators (210, 260, and 220) coupled to the plurality of matrix memories, a pixel brightness detector (225), a soft switch (230) receiving control information from the pixel brightness detector, a dither circuit (235) to provide effective resolution to the correction information, and a processor (240) to add the correction information to an input video signal.
