Halo... LCD=LCD CRT is flat. The normal life of LCD is usually 2-4w hours, that is, it can be turned on for 5-8 hours every day, and it can be used for 8-10 years. However, there are many parts in it. If the LCD is broken, it can be regarded as reimbursement. The core components of LCD are liquid crystal layer, two polarizers and backlight module. The main components of backlight module are backlight tube and light guide plate. The backlight tube of mainstream desktop LCD is CCFL (cold cathode fluorescent lamp). Its principle is the same as that of neon lamp, but its diameter is very small. A single high brightness backlight tube often has a limited life, so in practical use, most use double or four tube design.. Under normal circumstances, the life of LCD mainly depends on the life of backlight lamp, and there is no problem when it is used for tens of thousands of hours. After a certain period of time, the backlight will be aging and the brightness will be reduced. At this time, the LCD can be reborn by replacing the backlight (it may need to be replaced by a professional manufacturer in a dust-free state). But generally speaking, there was no need to update the performance of this liquid crystal at that time_ ∩) ten years from now, it's still one thing for you to say that there's something good to come out of it. Is there anyone else working on these accessories. LCD life is quite short, only about 5 years, and in the process of use, brightness will gradually weaken..
