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.
