Overview
LC749402BG is a picture quality improvement IC that processes the output signals to the LCD panel for high picture
quality display. This IC performs various picture quality adjustments to provide the ideal correction for the display
panel.
It can support up to WVGA/SVGA panels. *
Features
(1) Digital input/output
• Digital YCbCr/YPbPr 24bit (4:4:4) or 16bit (4:2:2) or 8bit(ITU-R BT.656) signal input
• Digital RGB 24bit signal input
• Digital RGB 18bit/24bit signal output
• Digital YCbCr16bit (4:2:2)/24bit (4:4:4) signal output
(2) Image quality correction
• Y image quality correction: luminance adjustment, contour correction, CDEX (Color Depth Expander), dynamic-γ,
black/white stretch
• C image quality correction: color exciter, flesh tone correction, hue, color gain
• RGB image quality correction: brightness, contrast, white balance, black balance, γ correction
(3) Panel interface
• Built-in panel driver timing controller
• Panel protection timing signal generation
• Backlight control PWM (video adaptive low power consumption processing)
*: The LC749402BG video input should satisfy the following conditions:
40MHz or less operating frequency, 896 dots or less horizontal size, 768 lines or less vertical size.
