The working principles of high brightness LED stage lighting screens are grounded in the fundamental properties of LEDs and the principles of digital signal processing for both display and lighting control. At the core of the operation, when an electric current is applied to an LED, the semiconductor material within the LED undergoes a process called electroluminescence. In the case of RGB (Red, Green, Blue) LEDs, which are commonly used in stage lighting screens, the red, green, and blue semiconductor regions emit light at specific wavelengths corresponding to the primary colors of light when an electric current passes through them.

For the display function, digital content, such as pre - recorded videos, live camera feeds, or computer - generated graphics, is first processed by a control system. The control system receives the digital video signal from various sources, such as a computer, media server, or video switcher. It then decodes the signal and breaks it down into individual frames. Each frame is further divided into pixels, and for each pixel on the screen, the control system calculates the appropriate intensity values for the red, green, and blue LEDs based on the color information in the frame.

These calculated intensity values are then transmitted as electrical signals to the LED modules. The signals are sent at a high frequency, allowing the LEDs to rapidly switch on and off or adjust their brightness levels. By precisely controlling the intensity of each primary color in every pixel, the LED screen can create a vast array of colors and shades, enabling the reproduction of detailed images, videos, and dynamic visual content on the stage. The refresh rate of the LED screen, which refers to the number of times the screen updates its image per second, is a crucial parameter.
