Zero light output
No backlight bleed, no grey haze, no halo. The panel is genuinely dark, which is what makes a black screen useful for sleep, night feeds and darkroom work.

Protect your panel
Leaving it on for hours on an OLED? Turn on burn-in protection so the image shifts a few pixels every 30 seconds.
Why pure black matters
On OLED, black is not dark — it is off.
OLED and AMOLED panels light every pixel individually. When a pixel is asked for #000000 it stops drawing current altogether: no light, no power, no wear. That single fact is why a real black screen is both the darkest thing you can put on the display and the most efficient.
Lower power draw
A fullscreen black page draws only what the panel controller needs. On an OLED phone this can be a fraction of the draw of a white page.
Less burn-in risk
A static bright image is what burns in. Pure black plus our optional pixel-shift mode gives those pixels the quietest possible shift.

FAQ
Common questions
Is this really #000000?
The stage background is set to the exact hex value #000000 with no opacity, no gradient and no overlay, so on OLED panels those pixels are switched off entirely.
Does it work on an LCD or LED screen?
Yes, and it is still the cleanest dark screen available — but an LCD backlight stays lit behind black pixels, so you will not see the same battery savings. On those panels a very dark grey is often easier on the eyes than true black.
Why does fullscreen behave differently on iPhone?
Safari on iOS does not allow arbitrary elements to enter fullscreen. When that happens we open a locked fullscreen overlay that hides the page behind it and removes scrolling, which behaves almost identically in practice.
Can I keep the black screen on all night?
You can. Combine keep-awake with burn-in protection and, if you like, the auto-off timer, which fades the screen out after 30, 60 or 120 minutes so it does not stay lit until morning.
How do I exit?
Press Escape, or tap the exit control that appears when you move the pointer or touch the screen. On the fallback overlay the same control closes it.
How do I use this black screen?
Tap the black panel to fill your display, or press the Fullscreen button. On a desktop you can also press F or Space. The stage is painted with a true #000000 black screen, so there is nothing to load. Use the quick colour swatches or the custom picker if you want a different tone, switch on Keep screen awake for long sessions, and turn on Burn-in protection when the screen will stay on for hours. Press Escape or tap the exit control to return to the page.
Is a black screen better for eyes?
For most people, yes. A pure black screen emits almost no light, so it does not glare at you in a dark room and sends far less blue-rich light to your eyes at night. That reduces the contrast your eyes have to fight and can ease strain when you read, rest or try to fall asleep. It is not a medical treatment and will not fix an eye condition, but as a screen choice a full black screen is the gentlest thing a display can show.
Does a black screen save battery on OLED screens?
Yes. On OLED and AMOLED panels every pixel makes its own light, so a black pixel is simply off and draws almost no power. A fullscreen black page can use a small fraction of the energy of a bright white one, which is why dark modes and black wallpapers help OLED phones, tablets and laptops last longer. On an LCD, LED or plasma screen the backlight stays on behind black pixels, so the display is darker but the battery saving is minimal.
How do I make my screen completely black online?
Open this page and tap the black panel or press F, and the whole display becomes pure #000000 in one step. There is no app and no signup. Android browsers hide the address bar for a truly full black screen; on iPhone and iPad, Safari will not let a page element go fullscreen, so we open a locked overlay with no scroll and no chrome so it looks the same. To keep a screen black for hours, add keep-awake and burn-in protection.
