An MCU (Microcontroller Unit) is a compact integrated circuit that includes a processor, memory, and input/output interfaces, designed to control specific functions of an electronic device. Unlike general-purpose computers, MCUs are optimized for dedicated tasks such as display control, sensor data processing, or touch panel operation. They are widely used in embedded systems, IoT devices, industrial automation, medical equipment, and automotive electronics.
MCUs can be programmed to respond to environmental signals – such as touch, motion, or temperature – and trigger defined actions like updating display content, sending data, or activating alarms. In display systems, MCUs are often responsible for initializing the panel, managing image settings, and handling user interfaces.
