The LED display is a display screen that uses LED lamp beads as display components, which can be used to display text, images, videos and other information. The advantages of LED display are high brightness, low power consumption, long life, and wide viewing angle, so it is widely used in various occasions, such as advertising, information release, display screen, etc. LED displays can be divided into LED digital tubes, LED dot matrix, LED flat light-emitting diodes and other types, among which LED digital tubes are one of the most common LED displays. 

LED digital tube is a digital display device composed of LED lamp beads, which can display digital information from 0 to 9. LED dot matrix is a flat light-emitting diode display device composed of LED lamp beads, which can display text, images, videos and other information. LED planar light-emitting diode is a planar light-emitting device composed of LED lamp beads, which can display text, images, videos and other information. The LED display can adjust the brightness and switch the displayed content according to the needs. In addition, the LED display can also perform operations such as timing playback and timing brightness adjustment according to needs to achieve more intelligent applications.
