The LED display screen is an electronic display screen composed of LED dot matrix. By turning on and off the traffic light beads to replace the screen display content forms such as text, animation, pictures, and video, the timely conversion is performed, and the component display control is performed through a modular structure. It is mainly divided into display module, control system and power supply system.
The display module is a dot matrix of LED lights to form a screen to emit light,the control system is to control the on and off conditions in the area to convert the content displayed on the screen, the power system is to convert the input voltage and current to meet the needs of the display screen.
The LED screen can realize the transformation between different forms of various information presentation modes, and can be used indoors and outdoors, and has incomparable advantages over other display screens. With the characteristics of high luminous intensity, low working power consumption, low voltage demand, small and convenient equipment, long service life, stable impact resistance and strong resistance to external interference, it has developed rapidly and is widely used in various fields.
