OLED Display Pure Black Wallpapers

Black background wallpapers benefit the life of OLED displays in several ways:

Reduced Power Consumption: One of the characteristics of OLED (Organic Light Emitting Diode) technology is that only the light emitting pixels consume power. Black pixels are virtually non-emitting, so using a black background significantly reduces power consumption. This not only helps to extend the battery life of devices (e.g., cell phones, TVs), but also helps to reduce overall energy consumption.
Reduced heat buildup: Because black pixels do not emit light, they do not generate heat. Reducing heat buildup prevents thermal damage to the organic materials of the display, thus extending the life of the display.
Reduced screen aging: The organic materials in OLED screens will gradually age as they emit light. Since black pixels do not emit light, more pixels on the screen are “off” when a black background is used, which reduces the aging rate.
Reduces Image Residual (Screen Burn): Prolonged display of high brightness images can cause some pixels to age faster than others, resulting in image residual or “screen burn”. The use of black background can effectively slow down this phenomenon because black pixels do not emit light, so it will not cause screen burning due to prolonged display.

The use of black background wallpapers can effectively reduce power consumption, reduce heat buildup, slow screen aging, and reduce the risk of screen burn-in, thereby extending the life of the OLED display.
