Ultra Low Cost LCD Controller

Product Status: 量産中

OVERVIEW

The TW8819 is an ultra low cost highly integrated LCD controller. It combines a high quality 2D comb NTSC/PAL/SECAM video decoder, high quality scaler, Font based OSD engine, and image enhancement functions. It also supports panoramic scaling for conversion to wide screen display. The TW8819 supports analog composite video inputs and the output supports a wide variety of digital LCD panel types.
