Energy consumption of dark vs light display background

[Simon]

What uses less battery: Dark or light display background? How much difference does that roughly make during an activity?

Since the display in dark when powered off, I assume, making it light/white consumes energy. Hence, light background could be more demanding …

@simon it doesn’t matter. It’s only relevant for OLED displays.
