    Except OLED. It’s better for OLED to show white text on black background.

      Every software needs a “just turn off the pixels that aren’t displaying anything” mode for OLED. Way too many “dark modes” are just dark grey which still keeps the background pixels powered.

        No because the white parts are what will burn in. Black is the off state for OLED. This is also why many apps for Lemmy (and previously reddit) have a dark theme option for OLED devices that uses full black instead of grey so that the pixels not in use are fully off.

          Exactly, and because the rest is off you’ll notice it earlier. It still depends on how long those pixels are on though. The longer they’re on the more they degrade.

          If the whole display is on all of the pixels would degrade eventually, but you’ll notice it less because they all degrade.

            If you have the same pixels on all the time then yes you’d have faster burn in. However, since you’d be looking at different text, this degradation would be spread over the different pixels. Not uniformly, but good enough that it doesn’t matter for practical usage.
