LC749403BG

www.DataSheet.co.kr Ordering number : ENA1948 CMOS IC LC749403BG Overview Silicon gate LCD Picture Quality Improvement IC 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. *...
