Features

The TW8807 is a low cost high quality TFT panel controller with embedded NTSC/PAL/SECAM TV decoder. It incorporates all the features required to create multi- purpose LCD TV systems in a single package. It contains all the circuits required to adapt standard NTSC/PAL/SECAM analog TV input signals for display on various TFT LCD panel types. An integrated timing controller and three DACs allows direct interface with analog LCD panels. Its versatile 5 analog inputs allow CVBS, S-video signal to be connected simultaneously. Other features include: high quality adaptive 4H Comb Filter, downscaling to QVGA output resolution, 2D de- interlacer and panoramic scaler, and multi-window programmable OSD. It also includes image enhancement functions, such as black and white stretch, 2D peaking, CTI, and favorite color enhancement to further improve picture quality. To support analog panel, it also includes cost saving features like charge pump booster and programmable panel offset control.
