Control system: The control system is the brain of the LED display, responsible for receiving input signals from computers, video processors and other equipment, and controlling the LED display to achieve various display effects.

Video processor: The video processor is one of the core components of the LED display, which can process and adjust the input video signal to improve the display effect of the LED display.

Power supply: The LED display needs to use a power supply to power the light-emitting diodes. There are two commonly used power supplies: AC power supply and DC power supply.

Power adapter: The power adapter is a device that converts power into the voltage and current required by the LED display.

Air conditioner: LED display screens have certain requirements on the ambient temperature, and usually need to install an air conditioner to keep the ambient temperature stable.

In short, the LED display is a system engineering composed of multiple parts, and different parts cooperate with each other to realize the display effect and function of the LED display.
