The reason why backlight shortens life

一、Exposure to the sun or rain for a long time

    Many products cannot be exposed to the sun regularly, otherwise the outer shell will become more fragile, and frequent rain will accelerate the aging and rust of the internal parts. The backlight is often attached to the back of the LCD screen. If it is used outdoors, frequent exposure to the sun will shorten the life of the backlight, and rain or water will also weaken the effect of the backlight.

 

二、Use it for a long time

There is a limit on the working hours of a day. After that limit, you will feel tired. The backlight is also used for a long time. The surface temperature will increase and the internal parts will work under load, which will greatly reduce the cycle time of its use. It should be opened when it is needed for use and closed briefly for rest when it is not needed.

 

三、The current used is too high

Under normal circumstances, the voltage used is fixed, and the product is used within the specified current range. However, if the backlight source used is a product that has been rebuilt by itself, it is possible to change the range of its current, so that the backlight source is burning life, and the service life will be shortened accordingly.

 

Under normal circumstances, the service life of a good backlight is quite long, and it can be used for up to 10 years under reasonable use. However, if you do not pay attention to protection during use, the life will be shortened, and the backlight will be in a load state if the power is not turned off for a long time. The precautions for the use of the backlight should be better understood and used correctly in order to improve the lifespan.
