LCD Picture Quality
Improvement IC
Overview
LC749403BG is a IC which enables higher picture quality in LCD products by improving the signals outputed to the
LCD panel. In addition to the function to improve the picture quality of the color equation and the brightness
correction, smooth picture quality is realized by converting One Seg video from 15fps to 30fps using flame
interpolation technique.
It supports up to WVGA resolution. *
Features
(1) Digital Input/Output
• Supports digital video input: YCbCr/YPbPr 24bit,16bit (4: 2: 2) signals or ITU-R BT.656 (8bit) input
• Digital RGB 24 bit signal input
• Digital RGB 18bit/24bit signal output
• Digital YCbCr 16bit/24bit signal output
(2) Picture Quality Improvement Function
• Y signal picture quality improvement: brigntness adjustment, contour correction,CDEX (Color Depth Expander),
• C signal picture quality improvement: color exciter,skin color correction,color and hue adjustment
• RGB signal picture quality improvement: brightness, contrast, white balance, black balance, gamma correction
(3) Panel Interface
• Embedded timing controller for panel driver
• Automtic timing signal generation for panel protection
• PWM for backlight control (video adaptation low power consumtion processing)
(4) Frame interpolation (×2) for One-Seg broadcast
• Double-speed (×2) mode (15fps ⇒ 30fps)
Intermediate image is predicted from the previous and next image.
*: Video input of the LC749403BG meets the following conditions:
(1) horizontal resolution is under 880 dots, and (2) vertical resolution is under 480 lines.
