What is a black screen used for?
A pure black screen has more practical applications than most people realise — from saving battery life on OLED displays to improving focus during deep work sessions.
OLED Power Saving
Black pixels on OLED/AMOLED displays draw zero power. A full black screen can cut display power consumption by up to 60%.
Focus & Deep Work
Eliminate all visual distractions. Pair with our Focus Timer for a complete Pomodoro workflow.
Video Calls
Use as a virtual background on Zoom, Teams, or Meet to maintain privacy during calls.
Monitor Testing
A pure black screen reveals backlight bleed, stuck pixels, and uniformity issues on any display.
Sleep Aid
Reduce blue light exposure before sleep by dimming your display to a pure black screen.
Screen Cleaning
A black background makes dust, fingerprints, and smudges on your screen clearly visible.
