Description
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 supports 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.
