Influence of P4 SMD Outdoor LED Display light source device performance

LED beads are the key components of the display screen as well as the components related to the life. For LED beads, the main indicators are the following: attenuation characteristics, water vapor permeability characteristics, uv resistance. If LED display manufacturers fail to pass the performance evaluation of LED beads, it will be applied to the display screen, which will lead to a large number of quality accidents and seriously affect the life of LED display.

In addition to the pearl light source of LED lamp, LED display screen also USES many other supporting parts, such as circuit board, plastic shell, switching power supply, connector, housing and so on. Any quality problem of any part may lead to the decrease of screen life. So, the life of the display is determined by the life of the key component with short life. For example, LED, switching power supply and metal shell are all selected according to the standard of 8 years, while the protection process performance of the circuit board can only support its work for 3 years. After 3 years, due to rust damage, we can only get a 7-year life of the display screen.
