TFT Flat Panel Controller with Built-in 3D Video Decoder, Triple ADCs, Dual PIP and 16-bit OSD Support

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.
