TW8816
Highly integrated LCD controller
with on-chip MCU & CCFL controller
The TW8816 is a highly integrated mutli-purpose LCD display solution with a high quality NTSC/PAL/SECAM 2D video decoder and a 2D
De-interlacer/Scaler supporting digital and analog panels. To reduce BOM cost, TW8816 integrates an 8-bit MCU and a CCFL controller. Through
multiple input ports, TW8816 can directly display video and graphic content from a variety of devices including TV Tuners, DVD players, back-up
cameras, DTV/DMB receivers and navigation/GPS receivers.
