CXD3503R
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.
64 pin LQFP (Plastic)
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
