TW8816B3
LCD Flat Panel Processor with Built-in MCU, NTSC/PAL/SECAM Decoder, T-CON
and Analog RGB Support
FN7794
Rev.3.00
September 27, 2012
General Description
The TW8816 is a highly integrated multi-purpose LCD display
solution for both analog and digital panels. To reduce BOM
cost, TW8816 integrates an 8-bit MCU and a CCFL or LED
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.
