LED Display Service Life

The led display screen can realize the conversion 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 brightness, low power consumption, low voltage demand, compact 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.

The luminous color and luminous efficiency of the LED are related to the material and process of making the LED. The light bulb is all blue at the beginning, and phosphor is added at the end. According to the different needs of users, different light colors can be adjusted. Red is widely used. , Green, blue and yellow. Due to the low working voltage of LED (only 1.2~4.0V), it can actively emit light with a certain brightness, and the brightness can be adjusted by voltage (or current), and it is resistant to shock, vibration and long life (100,000 hours), so Among large-scale display devices, there is no other display method that can match the LED display method.
