TFT Display Controller
TW8832, TW8832S
Description
The TW8832 incorporates many of the features
required to create multi-purpose in-car LCD display
system in a single package. It integrates a high
quality 2D comb NTSC/PAL/SECAM video decoder,
triple high speed RGB ADCs, high quality scaler, and
images enhancement functions, which include Black
and White Stretch, etc. It also supports panoramic
scaling for conversion to wide screen display. On the
input side, it supports a rich combination of CVBS, S-
video, analog RGB as well as digital inputs. On the
output side, it supports a variety of digital panel types
with its built-in timing controller.
