LCD monitors are ultra-thin display devices with thin bodies, space saving, power saving, no high temperature, low radiation, good health, and soft images that do not hurt the eyes. However, compared with traditional CRT monitors, the life of LCD monitors is significantly shorter. Among the various components of LCD and LED monitors, the LCD panel is the core, which accounts for 80% of the total cost of LCD monitors. The lamp in the component determines how long the LCD monitor has a life span. When the lamp brightness is reduced to 50%, the life span is defined. During such a usage period, the brightness changes with time. It presents a decreasing curve, so the longer the TFT LCD monitor is used, the lower the brightness will be.   At present, the life of the LED backlight of the LCD Display can reach more than 5W hours, and the brightness decay rate can be controlled within 3% of 10,000 hours. If it is used for 8 hours a day, it can be used normally for 15 years, but attention should be paid to the use environment and related matters.    The following are some suggestions to increase the service life of the LCD monitor:   1. It is recommended to work in a normal temperature/normal humidity environment. High temperature/high humidity will affect the life of the LCD monitor.   2. Intense temperature fluctuations will affect the performance of the LCD monitor, especially low temperatures will affect the brightness and response time. It is recommended to work in a stable and clean environment. Dust will cause internal circuit failure.   3. Do not let liquid splash into the monitor. If you need to clean it, please turn off the power, spray the detergent on a soft cloth and then wipe it gently.   4. The LCD monitor is a glass product. Avoid collision and vibration when moving it.   5. There are multiple layers of film on the surface of the LCD monitor. It is strictly forbidden to scratch it with a sharp tool.   6. It is strictly forbidden to disassemble the LCD monitor at will. If there is a fault, be sure to ask a professional to repair it.   7. Displaying a fixed screen for a long time will reduce the brightness and increase the image retention phenomenon. It is recommended to use a screen saver.   8. Please turn off the monitor power and unplug the power plug if you don't use it for a long time.
