1. What is LED display LED display is a flat panel display, which is composed of lamp points with a certain spacing and specifications, and each lamp point is composed of a single LED light-emitting tube. It uses light-emitting diodes as display elements, and controls the display mode of semiconductor light-emitting diodes to display various information such as text, graphics, images, animations, quotes, videos, and video signals.

2. Working principle of LED display The working principle of LED display is to use the characteristics of light-emitting diodes to form an array of LED devices through a certain control method to form a display screen. Each LED represents a pixel, and the LEDs in the LED display are organized into different columns and rows to form a grid-like structure. When specific content is to be displayed, the required image or text can be created by controlling the brightness and color of each LED. The brightness and color of the LED can be controlled by digital signals. The control system of the display will send the input digital signal to the corresponding LED to control its brightness and color. In order to achieve high brightness and clear display effects, the change of display brightness is controlled by constantly switching the on and off state of the LED. LED display screens can also use full-color LED technology, that is, combining three different colors of LEDs, red, green and blue, to display colorful images through different combinations of brightness and color. LED display screens are mainly composed of the following parts: LED unit board: This is one of the core display components of LED, consisting of LED modules, driver chips and PCB circuit boards. Accessories and equipment, such as front panels, boxes, protective covers, etc.

3. Characteristics of LED display screens The characteristics of LED display screens are mainly the following: High brightness: The brightness of LED display screens is high, and they can be used outdoors all day and night, and can also be used indoors. Long life: The service life of LED display screens is long, generally reaching more than 100,000 hours. Large viewing angle: The viewing angle of LED display screens is large, and the viewing range is wide. The audience can watch the screen from different angles. Flexible size: The size of LED display screens can be designed according to needs, ranging from less than one square meter to hundreds or thousands of square meters. Energy saving and environmental protection: LED display screens are powered by low voltage, have low power consumption, and are environmentally friendly and pollution-free. High reliability: LED display screens have high reliability and can work under harsh environmental conditions, such as high temperature, low temperature, and humidity. Real-time: LED display screens can display various information in real time, such as news, advertisements, notifications, etc. Efficiency: LED display screens have a fast update speed and can complete the update and display of information in a short time. LED display screen structural frame engineering: LED display screen structural frame engineering mainly includes steel structure, aluminum profile, grid structure, etc., which are used to support and fix the various components of LED display screen.
