Aging test site of LCD splicing screen
Many people who don't know about LCD splicing screen may not know that LCD splicing screen, as a kind of precision instrument with more scientific and technological elements, must go through a series of tests and screening before the product is shipped; among them, the aging test of the product is the top priority, and the aging test can propose solutions based on the failure rate curve of the product and the problems in various aspects, so as to ensure the safety of the product The reliability of product quality in the later stage ensures that customers can get the best experience in practical application.

In the process of aging test, we should pay special attention to the following problems:
1. Test content: white screen, red, green, blue monochrome, gray gradient, video effect, text effect. 2. The test time of LCD splicing screen white screen shall not be less than 24 hours 3. Single color and gray gradient test shall not be less than 24 hours 4. Video and text effect test shall not be less than 24 hours 5. The aging test of LCD splicing screen must be attended by someone. If any problem is found, it can be reported in time for handling, and corresponding countermeasures shall be formulated

LCD splicing screen aging methods include constant current aging and constant voltage aging; constant current source means that the current is constant at any time. If there is a frequency problem, it is not a constant current. That is AC or pulsating current. AC or pulsating current source can be designed to have a constant effective value, but this kind of power source cannot be called a "constant current source". Constant current aging is the most scientific method for aging of LCD splicing screens, which is most in line with the current working characteristics of LCD splicing screens. Overcurrent impact aging is also the latest aging method adopted by manufacturers. This type of aging is carried out by using a constant current source with adjustable frequency and adjustable current in order to judge the quality and expected life of the LCD splicing screen in a short time, and can be selected Many hidden dangers of conventional aging cannot be singled out for LCD splicing screens.
