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