Digital LCD Panel Processor with built-in MCU,
NTSC/PAL/SECAM Decoder and TCON
TW8817
Applications
•Mobil LCD TVs
• Rear seat entertainment
• Portable DVD, PMP and HMD (Head Mount Display)
Features
The TW8817 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 low cost 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 allows direct interface with digital LCD panels. Its
versatile analog inputs allow CVBS, S-video, signal to be
connected simultaneously.
Other features include: high quality adaptive 4H Comb Filter, 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. it
also includes cost saving feature like CCFL and LED controller,
charge pump booster and programmable panel offset control.
In addition, TW8817 has built-in microcontroller with external
SPI interface.
