LED display screen is an electronic display screen composed of LED dot matrix. It can change the content form of the screen by turning on and off the traffic light beads, such as the timely conversion of text, animation, pictures and video, and control the component display through the modular structure.It is mainly divided into display module, control system and power supply system. The display module is composed of LED light lattice, and the screen emits light; The control system is to adjust and control the lights in the area to realize the conversion of the content displayed on the screen; The power supply system converts the input voltage and current to meet the needs of the display screen.LED screen can realize the transformation between different forms of a variety of information presentation modes, and can be used indoors and outdoors. It has incomparable advantages over other displays. With the characteristics of high light intensity, low power consumption, low voltage demand, small and convenient equipment, long service life, stable impact resistance and strong external interference resistance, it has developed rapidly and is widely used in various fields.The luminous color and luminous efficiency of LED are related to the material and technology of making LED. At the beginning, the lamp ball is all blue light, and then with phosphor, different light colors can be adjusted according to the different needs of users. Red, green, blue and yellow are widely used.Because the working voltage of LED is low (only 1.2 ~ 4.0V), it can actively emit light and has a certain brightness, and the brightness can be adjusted by voltage (or current), and it is shock resistant, vibration resistant and has a long service life (100000 hours), so there is no other display mode that can match the LED display mode in large display equipment.. monitor.
