... Color Shading Correction IC for Liquid Crystal Projectors Description The CXD3503R is a color shading correction IC for Sony data projectors. Used together with the Sony LCD driver CXA2111R or CXA2112R, this IC corrects color shading caused by the LCD panel structure or the optical system. This IC has a built-in SRAM and D/A converter, and 16 horizontal and 13 vertical correction points can be set via a serial interface ...
