The factors that affect the life of LED display screens are classified into internal and external factors. The internal factors include the performance of LED light-emitting devices, the performance of peripheral components, and the anti-fatigue performance of the product; the external factors include the working environment of the LED display screen, etc.
1. The influence of the performance of LED light-emitting devices
LED light-emitting devices are the most critical and life-related components of the display screen. For LED, the main indicators are: attenuation characteristics, water vapor penetration characteristics, and UV resistance. If the LED display manufacturer fails to evaluate the performance of the LED device indicators, it will be applied to the display screen, which will lead to a large number of quality accidents and seriously affect the life of the LED display screen.
2. The influence of peripheral components
In addition to LED light-emitting devices, LED display screens also use many other peripheral components, including circuit boards, plastic shells, switching power supplies, connectors, casings, etc. Any problem with any component may lead to a reduction in the life of the display screen. Therefore, the longest life of the display screen is determined by the life of the shortest key component. For example, LED, switching power supply, and metal shell 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, and we can only get a 3-year life display screen.
3. Influence of product fatigue resistance
The fatigue resistance of LED display products depends on the production process. The fatigue resistance of modules produced by 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 protection performance.
Therefore, the production process of LED display is also a key factor in determining the life of the display. The production processes involved in the production of display screens include: component storage and pretreatment process, furnace welding process, three-proof treatment process, waterproof sealing process, etc. The effectiveness of the process is related to material selection and ratio, parameter control and operator quality. For most LED display manufacturers, the accumulation of experience is very important. A factory with many years of experience will be more effective in controlling the production process. Therefore, Mairui Optoelectronics has accumulated many years of production experience and has been striving for excellence in the production process of LED display screens, becoming a benchmark for LED companies in the industry.
4. Influence of working environment
Due to different uses, the working conditions of display screens vary greatly. From the environmental point of view, the temperature difference indoors is small, without rain, snow and ultraviolet rays; the temperature difference outdoors can reach up to 70 degrees, plus wind, sun and rain. Harsh environment will accelerate the aging of the display screen, and the working environment is an important factor affecting the life of the display screen.
