LED Display

The LED display screen solution mainly consists of three parts: LED modules, control systems, and power supply. The LED module is the basic unit of the display screen, composed of multiple RGB LED beads arranged in an array; the control system is responsible for controlling the display content, typically including control cards and related software; the power supply provides stable power to the LED modules, ensuring excellent display performance. These three components work together to achieve high-quality visual presentation.
