The factors affecting the life of LED display screen include internal and external factors, including the performance of peripheral components, the performance of LED light emitting devices, and the fatigue resistance of products; Internal factors include the working environment of LED display screen, etc.
(1) Peripheral component impact
In addition to LED light-emitting devices, LED displays also use many other peripheral components, including circuit boards, plastic shells, switching power supplies, connectors, chassis, etc. Any problem with one component may reduce the life of the display. Therefore, the long life of the display screen is determined by the life of the key component with short life. For example, LED, switching power supply and metal housing are all selected according to the 8-year standard, while the protective process performance of the circuit board can only support its work for 3 years. After 3 years, it will be damaged due to corrosion, so we can only get a 3-year display screen.
(2) The Influence of LED Light Emitting Device Performance
LED light emitting devices are the key and life related components of the display screen. For LED, it mainly includes the following indicators: attenuation characteristics, water vapor permeability characteristics, and ultraviolet resistance. If the LED display manufacturer fails to pass the evaluation on the indicator performance of LED devices, it will be applied to the display, which will lead to a large number of quality accidents and seriously affect the life of the LED display.
(3) Effect of fatigue resistance of products
The anti fatigue performance of LED display screen products depends on the production process. It is difficult to ensure the anti fatigue performance of modules produced by poor three prevention treatment process. When the temperature and humidity change, the protective surface of the circuit board will appear cracks, leading to the decline of the protective performance.
