概览

Support is limited to customers who have already adopted these products.

The TW8826 is a low cost highly integrated multi-purpose LCD display solution with a high quality NTSC/PAL/SECAM 2D video decoder and a 2D De-interlacer/Scaler supporting analog panels. To reduce BOM cost, TW8826 integrates an 8-bit MCU and a CCFL controller. Through multiple input ports, TW8826 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.
