TFT Flat Panel Controller with Built-in 3D Video
Decoder, Triple ADCs, Dual PIP and 16-bit OSD Support
TW8823C
The TW8823C incorporates many of the features
required to create a multi-purpose in-car LCD display
system into a single package. It integrates a high quality
3D comb NTSC/PAL/SECAM video decoder, triple high
speed RGB ADCs, high quality scaler, bit-mapped OSD,
triple DACs and image enhancement functions which
include Black and White Stretch, favorite color
enhancement, etc. It also supports panoramic scaling for
conversion to wide screen display format. On the input
side, it supports a rich combination of CVBS, S-video,
analog RGB as well as digital YCbCr/RGB. On the output
side, it supports both digital and analog panel types with
its built-in timing controller and analog RGB output. In
addition, the TW8823C supports LVDS type panels.
The TW8823C also has two PIP (Picture in Picture)
engines that can display three display sources
simultaneously in a single window. It also has a built-in
bit-mapped OSD with 16-bit color depth and an
acceleration function. It can also accept 18-bit external
OSD inputs. In addition, TW8823C has a built-in high
performance microcontroller with cache. Its SPI interface
supports various serial flash types.
