Dark idle state
Keep the screen on without showing bright windows or white pages.
For dark idle displays
Use a darker screen when the display must stay on
Use a fullscreen black display when an OLED device or low-light setup needs to stay active with minimal visual output.
Why a black screen saves power
On OLED displays, dark pixels draw less power than bright windows and white pages.
OLED-friendly use case
Black output is especially relevant on OLED-style screens where black pixels behave differently from LCD backlights.
Useful for audio and night setups
Cover the screen while music, sleep audio, or another background task continues.
