MS1861 Video Processor and LCD Driver
The MacroSilicon MS1861 is a video processor and LCD display controller. A single chip integrates HD, LVDS, and digital video inputs, driving MIPI DSI-2, LVDS, Mini-LVDS, and TTL TFT-LCD panels.
It supports filtering, image enhancement, sharpening, contrast adjustment, video scaling, clipping, rotation, OSD overlay, and frame-rate conversion. Gamma and dithering can be applied for TFT-LCD characteristics, with panel timing generated by the integrated TCON. The chip includes an ARM processor, DDR3, and UART, I2C, SPI, PWM, GPIO, and ADC peripherals.
