Highly Integrated LCD Controller with On-Chip MCU & CCFL Controller

Product Status: Mass Production

OVERVIEW

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.

KEY FEATURES
