1, The impact of technical principles and composition on lifespan


2, Comparison of service life
LCD screen: The service life of LCD screens is affected by various factors, including backlight modules, liquid crystal layers, driving circuits, etc. Among them, the light source in the backlight module is one of the key factors affecting its lifespan. Before the popularization of LED backlight technology, the lifespan of CCFL backlit LCDs was relatively short because CCFL tubes were prone to aging and had high replacement costs. However, with the widespread application of LED backlight technology, the overall lifespan of LCD screens has been significantly improved. Under normal usage conditions, high-quality LED backlit LCD screens can work for tens of thousands of hours without significant performance degradation.
