LED full-color display is a device widely used for information display and advertising. It uses LED (Light Emitting Diode, light-emitting diode) to display color images and text. The working principle of LED full-color display screen involves the luminous characteristics of LED and electronic control system. Do you understand the working principle of LED interactive floor tile screen? The following are the basic steps of the working principle of LED full-color display:

Light Emitting Diode (LED): LED is the core component of this display. They are semiconductor devices that can emit light. LEDs can be divided into three basic colors: red, green and blue. These three colors of LEDs can be synthesized into various colors, including white.

Color Mixing: Full-color LED displays typically contain hundreds or thousands of red, green and blue LEDs. By adjusting the brightness and light combination of each color LED, millions of different color displays can be achieved. This is called color mixing and creates the desired color by controlling the brightness of each color channel.

Control system: The LED full-color display is equipped with a control system, which usually uses a dedicated LED display control card or other electronic control equipment. These control systems receive image and video signals from computers or other input sources and convert them into control signals required for LED display. These signals control the brightness and color of the LEDs so that images can be accurately rendered.

Pixels and resolution: LED full-color displays are composed of many small LEDs, which are usually arranged into a pixel array, similar to a TV or computer screen. Resolution refers to the number of pixels on a display, which determines the screen's clarity and level of detail.

Refresh rate: LED full-color displays work at a very high refresh rate, usually refreshing images dozens to hundreds of times per second. This ensures smooth display of video and dynamic content.

In short, the working principle of LED full-color display involves the luminous characteristics of LED, color mixing, electronic control system and pixel array. With proper control and combination, they can display rich color images and videos.
