TFT Flat Panel Controller with Built-in 3D Video Decoder, Triple ADCs, Dual PIP
and 16-bit OSD Support
The TW8823 incorporates many of the features required to
create multi-purpose in-car LCD display system in 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 images
enhancement functions which include Black and White
Stretch, favorite color enhancement and 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 YCbCr/RGB inputs. On the output
side, it supports both digital and analog panel type with its
built-in timing controller and analog RGB output. It also
support LVDS type panel.
TW8823 also has two PIPs (Picture in Picture) function that
can display three display sources simultaneously on one single
window. It also has built-in bit-mapped OSD with 16-bit color
depth and acceleration function. It can also accept 18-bit
external OSD input. In addition, TW8823 has built-in high
performance microcontroller with cache. Its SPI interface
supports various serial flash types.
