MCUs like STM32 and i.MX RT1050 series have a 24-bit parallel RGB interface for displays. RGB to MIPI DSI converters allow DSI displays.
Some useful MIPI DSI PCB layout notes, guidelines and tips for MIPI DSI systems. Applicable to MCUs such as STM32 and STM32MP1.
Can you use a 4 lane MIPI DSI display with a 2 lane DSI host? STM32 series, RT1050, etc tend to have a 2 lane DSI host.
