LED display due to installation engineering and late maintenance and other factors, the production process must go through the aging stage before the factory.Derensel also introduced to you today, aging test is to simulate whether there will be abnormal in the long working hours, is an important guarantee for the reliability of electronic products, is the last essential step of product production.After aging, the product can improve the efficiency and contribute to the stability of the performance of later use.Led display aging test is a very important link in product quality control, aging test is based on the product failure rate curve that is the characteristics of the bathtub curve and the countermeasures to improve the reliability of the product.

The aging methods include constant current aging and constant pressure aging.A constant current source is one in which the current is constant at any time.If you have a frequency problem, it‘s not a constant current.That‘s alternating current or pulsating current.Ac or pulsating current sources may be designed to have constant effective values, but they cannot be called "constant current sources".Constant current aging is the most consistent with LED current working characteristics, is the most scientific LED display aging mode;Overcurrent impact aging is also the latest aging method adopted by manufacturers. The constant current source with adjustable frequency and current can be used for this kind of aging, so as to judge the quality life expectancy of led display screen in a short time, and to pick out many hidden dangers of led display screen that cannot be picked out by conventional aging.

You are familiar with the aging of products, so you know that these methods used in the aging process may lead to overheating of products, or circuit failure.These problems will cause fire to a certain extent, so the production workshop must be prepared for fire prevention, and in the night when there is aging products need to arrange the corresponding personnel inspection, in the first time the fire extinguish, reduce the loss of the factory.
