描述
The TW8835 incorporates many of the features required to create multipurpose 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, versatile OSD and high performance MCU. Its image video processing capability includes arbitrary scaling, panoramic scaling, image mirroring, image adjustment and enhancement, black and white stretch, etc. On the input side, it supports a rich combination of CVBS, S-video, component video, analog RGB as well as digital YCbCr/RGB inputs. On the output side, it supports a variety of digital panel types with its built-in timing controller. The integration of additional touch screen controller, LED driver controller, PWM and MCU makes this a versatile solution for many portable applications.
