What good-looking black mobile phone wallpapers are there?

The topic requirement is good-looking black mobile phone wallpaper, as shown in the figure: only the mobile phone with organic light-emitting diode screen uses black wallpaper to save electricity, while the mobile phone with LCD screen uses any color wallpaper, so there is no difference in power consumption.

LCD is a liquid crystal display, and the screen itself does not emit light. When displaying, you need to rely on the backlight lamp to emit light, so even if you use all-black wallpaper, the picture you see on the LCD screen is all black, but the backlight is still working.

Extended data organic light emitting diode is the abbreviation of organic light emitting diode, which has self-luminescence and does not need the support of backlight. That is to say, after the OLED uses all-black wallpaper, all pixels on the OLED screen do not emit light, which is close to the off-screen state.

In addition, even if it is not all-black wallpaper, even if only one pixel needs to emit light, the OLED screen can only emit light at one pixel, while other pixels are in a static state, which naturally saves more electricity.

In addition to the advantages of self-luminescence, organic light-emitting diode screens also have the advantages of wide viewing angle, high contrast, low power consumption, fast response, full color, simple process and strong flexibility. Therefore, in recent years, more and more flagship mobile phones have adopted organic light-emitting diode screens.
