Ultra Low Cost LCD Controller
TW8819
Description
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.
