As the name implies, off-screen display means that you can see the time without bright screen. In fact, this function seems useless, but sometimes it can be much more convenient. For example, it can be used when you wake up in the middle of the night and want to check the time, or when it is inconvenient to press the power button.
Bian Xiao thinks this function is a particularly practical function, which is very convenient for us to check the time when we just wake up or at night. Under normal circumstances, when we light up the screen of the mobile phone to check the time, it will bring strong discomfort to our eyes. After all, when the sudden strong light hits our eyes, everyone's eyes can't stand it. So the benefits of screen extinction are reflected.
Therefore, as long as Huawei's mobile phone uses the model of organic light-emitting diode screen, there will be an information screen to display this function, while the model of LCD screen is gone. The method of setting is also very simple. Just find the "off-screen display" item in the desktop and wallpaper and open it. If it is a Huawei mobile phone with an LCD screen, you can't see this function.
