small size display
Overview
LC74900 is a highly integrated multi-purpose LCD Panel (up to WVGA) controller processing analog and digital video
signal.
It contains A/D converter, video decorder, De-interlacer/Scaler, and picture improvement.
Features
(1) Video Input/Output
• Analog input: 4ch CVBS (NTSC, PAL, and SECAM) with 1ch 10bit A/D converter
• Digital input: 24bit RGB and YCbCr, 16bit YCbCr (4:2:2), and 8bit YC (BT.656)
• Digital output: 8bit video decoder output (BT.656)
(2) YC separation video decoder
• Adaptive 3line comb filter, automatic gain and chrominance control
(3) De-interlacer and Scaler
• Horizontal and vertical programmable scaler separately, and supports panels up to WVGA resolutions
(4) Picture Improvements
• CDEX (Color Depth Expander): high quality expansion for low-resolution graphics
• Dynamic gamma correction: picture adapted automatic luminance control
• Sharpness control, LTI and CTI: peaking enhancement without glares
• Color exciter: 6 phases RGBYMC gain control separately
(5) Panel interface
• 24bit RGB output and 18bit RGB output with dithering process
• Pulse Width Modulation for automatic LED backlight control
• Timing conroller for LCD driver with horizontal or vertical reversing signals
• Pin swapping : replace output pin assignment of the RGB channel or bit
