The influence of LED light-emitting devices
1. The influence of LED light-emitting device performance
The LED light-emitting device is an important and life-related component of the display screen. For LEDs, the following indicators are mainly: attenuation characteristics, waterproof and vapor penetration characteristics, and UV resistance. If LED display manufacturers fail to evaluate the performance of LED devices, they will apply them to the display, which will lead to a large number of quality accidents and seriously affect the life of the LED display.
2. Influence of peripheral components
In addition to LED light-emitting devices, LED displays also use many other peripheral components, including circuit boards, plastic housings, switching power supplies, connectors, chassis, etc. Any problem with any component may lead to the life of the display. reduce. Therefore, the longest life of the display screen is determined by the life of the key component with the shortest life. For example, LEDs, switching power supplies, and metal casings are all selected according to the 8-year standard, and 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 rust, so we can only get a piece for 3 years. life span of the display.
3. The influence of fatigue resistance of products
The fatigue resistance of LED display products depends on the production process. The anti-fatigue performance of the modules made by the poor three-proof treatment process is difficult to guarantee. When the temperature and humidity change, cracks will appear on the protective surface of the circuit board, resulting in a decrease in the protective performance.
