There are different opinions about whether the color of wallpaper affects the life of LCD. In fact, even LCD manufacturers have no evidence to show that what color will affect the life of LCD, so this is simply nonsense. I would like to ask: when the LCD is working, can it display only one wallpaper and not other pictures?

In addition, whether to use the screen saver does have relevant theoretical basis, which is now extracted as follows:

Recently, I always see some friends open the screen saver of laptop and leave it there for a long time. In fact, setting screen protection for LCD computers will not only fail to protect the LCD screen, but also shorten its life. So if you use a computer with an LCD screen, please turn off the screen saver of your operating system!

Let me talk about the principle. In fact, the reason is very simple. The traditional CRT display, like the traditional TV set, will have a large cavity, which is actually a cavity full of transverse and longitudinal electromagnetic fields. There is a spray gun at the end of the screen, which ejects charged particles and then emits them to different positions of the screen through electromagnetic fields with different intensities in the cavity. So that we can see the image on the screen.

Because early displays were basically displayed according to this principle, most operating systems were equipped with screensavers to prevent ordinary CRT monitors from displaying the same static picture frequently. Because the same static picture is displayed for a long time, some areas of the screen will be strongly impacted for a long time, which will lead to aging phenomena such as discoloration in some areas of the display. Because when moving the picture, the probability of each part of the screen being strongly impacted is very even. In this way, everyone should understand why CRT monitors need to use screensavers.

The reason why LCD doesn't need a screensaver is that its luminous principle is not that charged particles impact the screen. It directly applies voltage to the LCD panel, making it display different colors in different proportions of red, yellow and green. The best way to turn off the LCD screen when not in use. Because of this, no voltage is applied to the transistors in the liquid crystal, and the white tube that illuminates the LCD screen does not need to be lit for a long time. On the contrary, when the screen saver is turned on, the LCD screen is actually working at full load and there is no rest at all.

So if you use a computer with an LCD screen, please turn off the screen saver of your operating system!
