LED Sign
Turn your phone into a scrolling neon LED sign — pick text, colors, speed and glow, then play fullscreen.
Turn your phone into a scrolling LED sign in seconds. Type up to 80 characters or tap a preset, pick neon colors, a font, glow and speed, then hit play — the message runs across the whole screen, big enough to read from the back of an arena or across an arrivals hall. If flashing light bothers you, keep Blink at 0.

Frequently Asked Questions
Q. How do I make a scrolling LED sign on my phone?
A. Type your message (up to 80 characters) or tap a preset, choose colors, font, speed, blink and direction, then tap Play fullscreen. Tap the screen to show the Exit button.
Q. Do I need to install an app?
A. No. The LED scroller runs in any modern mobile or desktop browser and is free; nothing is downloaded or installed.
Q. Will my screen turn off while the sign is playing?
A. Usually not: during playback the page requests a screen wake lock, which current Chrome, Edge, Safari and Firefox support. On older browsers, lengthen the auto-lock time in your phone settings.
Q. Is the blink effect safe if I am sensitive to flashing light?
A. Use caution: at the maximum setting the text flashes about three times per second. If flashing light bothers you or anyone nearby, keep Blink at 0, which is the default.
