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.

Functions
• Generates the color shading correction signals for the high-temperature polysilicon TFT LCD panels used in Sony projectors
• Supports various SVGA, XGA and SXGA signals using 1/2 dot clock input
• Vertical output signal interpolation using an internal arithmetic circuit
• Automatic determination of eliminated lines during pulse eliminator display when used together with the Sony timing generator ICs CXD2464R or CXD3500R
• Supports up/down and/or right/left inversion
• Supports LCD panel display area switching conversion functions
• Standby and correction OFF functions

Applications
    Liquid crystal projectors, etc.
