A black screen fills your whole display with deep, solid black in a single click. This free online black screen is ideal for testing OLED true black and backlight bleed, spotting stuck pixels that glow against the dark, saving battery on OLED devices, or simply resting your eyes with a calm dark background. Turn it fullscreen for a clean black surface, and adjust it to fit late-night use.
What is a black screen?
A black screen is a full-screen black display that asks each pixel to show as little light as possible. On OLED and AMOLED panels the pixels switch off entirely, producing true black and revealing any that stay lit; on LCD panels, black exposes backlight bleed and glow around the edges. That makes a black screen a key display-testing tool, a battery saver, and a low-strain background for reading or working in a dark room.
What people use a black screen for
Test OLED true black & bleed
On OLED the screen goes genuinely dark; on LCD a black screen reveals backlight bleed, clouding, and glow leaking from the panel edges.
Find stuck & bright pixels
Stuck or always-on pixels stand out instantly as bright colored dots against solid black, which white and light screens can hide.
Save battery on OLED
Because OLED pixels use no power when black, a black screen background noticeably reduces battery drain on phones and OLED laptops.
Rest your eyes & focus
A dark, distraction-free background is easier on the eyes at night and hides a glowing screen when you want the room dark.

Black screen FAQ
Does a black screen really save battery?
On OLED and AMOLED screens, yes — black pixels are switched off and draw almost no power. On traditional LCDs the backlight stays on, so savings are minimal.
How do I check for backlight bleed with a black screen?
Dim your room, go fullscreen black, and look at the edges and corners. Uneven bright patches or a foggy glow indicate backlight bleed or clouding on an LCD panel.
Can a black screen fix stuck pixels?
A black screen helps you find them; alternating rapidly between black and bright colors can sometimes revive a stuck pixel, though results vary by panel.
Is the black screen free to use?
Yes. It is completely free with no ads, no account, and no limits. Open the page and start using the black screen right away.
Does it work on phones and tablets?
Yes. The black screen runs in any modern mobile or desktop browser — iPhone, Android, iPad, laptops and desktops — with no app to install.
How do I enter and exit fullscreen?
Click the screen or press F to go fullscreen. Press Esc (or F again) to exit. On mobile, tap once to expand and swipe or tap to return.
Will a black screen hurt my eyes?
It is a steady light source, no harsher than any bright web page. Lower the brightness for comfort and follow the 20-20-20 rule on long sessions.
Is it safe for OLED displays?
Yes, especially with OLED protection turned on. For long use, keep brightness moderate (60–80%) so static color does not risk burn-in.
Can I download the black screen as an image?
Yes. Open Download, pick a resolution up to 8K, and save a lossless PNG of the black color for wallpapers, video editing, or graphic design.
When to use a black screen
Use a black screen for anything that benefits from darkness: OLED testing, spotting bright stuck pixels, saving battery, or a restful night-time background. Switch to a white screen when you instead need to find dark dead pixels or use the display as a light, and to gray when you want to judge overall panel uniformity.
