It can be seen that the life span of led digital screen is closely related to the application environment. For the display screen whose environmental variables can be determined, the life span can be ensured by selecting appropriate equipment and appropriate manufacturing technology. This process includes: life planning, process control, and reliability verification.
1 Life planning
Všeobecne, planning pays attention to the completion of functions and functional indicators, and life planning also pays attention to the functional indicators at a certain time or after a certain number of applications. The output of planning will affect the selection of equipment, production technology and verification methods. As long as sufficient life planning is carried out, the life of the display screen is likely to be controllable.
2. Pay attention to the process control of life
A useful plan needs a useful process to complete. In the process of commodity completion, there are many links that need to be controlled, including the selection and verification process of equipment, the usefulness of production technology, atď., which is different from the quality control process. This control process focuses on long life.
3 High-strength reliability verification
Initiate the use of high-intensity reliability verification to ensure that the life of the exported goods can be expected, including the verification of raw materials, the components of the technological process and the final verification of the goods, which is very important and often ignored. Consider several questions:
Can the selected LED be used for 5 rokov? Is it the seller’s commitment or its own verification? Is the method of verification useful?
4. Use function
V praxi, in order to meet the personalized needs of customers, LED manufacturers must complete the planning-production-delivery tasks in a few months. We have applied useful life control methods to several sets of super-large area landmark displays with an area of more than 1000 metrov štvorcových, and the calculation shows that the goods operate stably and excellently.
