description
TW8835 adopts many features that need to be built in an in-vehicle LCD display system, multi-purpose in a single package. It integrates high-quality 2D comb NTSC/PAL/SECAM video decoder, triple high-speed RGB ADC, high-quality, multi-function OSD scaling, high-performance MCU. Its image video processing capabilities include arbitrary scaling, panoramic scaling, image mirroring, image adjustment and enhancement, black and white elongation, etc., on the input side, it supports rich CVBS, S-video, component video, analog RGB combination, and digital YCbCr/RGB input. On the output side, it supports various digital panel types with its built-in timing controller. The integration of additional touchscreen controllers, LED driver controllers, PWM controllers, and microprocessors makes this a versatile solution for many portable applications.
