One, raw material description:
Well-known LED manufacturers have always been very cautious in the selection of raw materials, usually using foreign imported products and domestic famous products to ensure the quality of the display and long-term stable operation.
Inspection and testing:
1. General
Ensure inspection and experiment requirements to verify the degree to which the product meets the specified requirements, and formulate relevant procedures.
2. Purchase inspection and test
The engineering service department is responsible for the first purchase inspection and quality inspection. The inspection shall be carried out in accordance with the provisions of the procedure document. In case of urgent shipments under special circumstances, the products shall be marked and recorded accordingly, so that the products can be returned and replaced immediately if problems are found. Generally, products that fail the incoming inspection or test shall not be used.
3, production and debugging
The entire production process strictly implements a modern QC management system, from component screening, printed board production, small board testing, full-screen assembly and debugging, each process is strictly inspected and tested, and the finished product undergoes continuous 48-hour aging. Specific conditions extend the aging detection time, strengthen the system performance, and ensure the reliable operation of various devices.
4, Reliability and maintainability:
The system’s average trouble-free running time is greater than 5000 hours
The service life of the system is greater than 100,000 hours
The system has good reliability and maintainability
5, Factory inspection:
After the test of the screen body unit board is completed, the entire screen is burned in and simulated test run in the factory, the control, power distribution and software system are jointly adjusted, the entire screen is simulated, and the system is pre-accepted.
