General Description
The
TW8816B3
is a highly integrated multi-purpose LCD
display solution for both analog and digital panels. To reduce
BOM cost, TW8816B3 integrates an 8-bit MCU and a CCFL or
LED controller. Through multiple input ports, TW8816B3 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.
