FAQ & about the LED scroller
FAQ — LED Scrolling Banner
What is an LED scrolling banner?
It turns your screen into a scrolling LED message board, like the dot-matrix signs you see at shops, stations and events. Type a message and it scrolls across the display as glowing LED dots — with adjustable speed, text size, colour, direction and scroll / static / blink modes. Popular searches it answers: scrolling text app, LED sign online, marquee display, concert banner for your phone.
How do I use it?
Type your message in the box — or tap a preset like OPEN, WELCOME or BACK IN 5 MIN. Pick a mode (scroll, static, blink), set the speed and text size, choose a colour (or 🌈 rainbow), then press Enter Fullscreen. Hold your phone sideways for the widest banner.
Does it work on a phone?
Yes — iPhone, iPad, Android and desktop. The fullscreen mode is iOS-safe, so the banner fills the entire screen on iPhone too (where Safari blocks the normal fullscreen API). On a portrait phone the banner auto-rotates to landscape, so you get the full width while holding the phone upright — ideal for holding a message up at a concert or arrivals hall.
How do I run it fullscreen?
Click the ⛶ fullscreen hint or the Enter Fullscreen button. Press Escape or the ✕ Exit button to leave. Press F on a keyboard as a shortcut.
Can I share my banner with someone else?
Yes — click 🔗 Copy share link. The URL contains your message, colour, speed, size and mode, so anyone who opens it sees exactly your banner, ready to go fullscreen. Send a birthday scroller by WhatsApp, prepare an OPEN sign for the shop tablet, or drop a surprise message on a colleague's screen.
Can the text blink or stay static instead of scrolling?
Yes. Besides classic scrolling (in either direction), Static mode shows the message centred and fixed, and Blink mode flashes it on and off like a real neon shop sign. Short messages such as OPEN, ON AIR or SOLD OUT work best in static and blink modes; long messages are made for scrolling.
Can I make a rainbow LED sign?
Yes — pick the 🌈 rainbow swatch and every column of LEDs gets its own hue, cycling smoothly through the spectrum as the message scrolls. Prefer a specific colour? Eight classic LED colours are one tap away, and the custom colour picker matches any brand colour exactly.
Can I use it as a digital OPEN or BACK IN 5 MIN sign?
Absolutely — that's one of its best uses. Put a tablet or spare monitor in your shop window, tap the OPEN or BACK IN 5 MIN preset, switch to static or blink mode and go fullscreen. It keeps running as long as the page is open, remembers your message for next time, and costs nothing — no digital-signage subscription needed.
How does the dot-matrix effect work?
Your text is rendered once to a hidden canvas, sampled into a grid of on/off dots, and each lit dot is drawn as a glowing LED with a soft halo — the same principle as a real dot-matrix display, where every character is formed from a matrix of physical LEDs. The text size slider changes the dot resolution, just like signs with finer or coarser LED pitch. Everything runs locally in your browser; your message is never uploaded.
Does it work offline?
Yes — once loaded, the banner runs entirely in your browser with no connection needed, and your message and settings are remembered on your device between visits.
Is it free?
Yes, completely free. No account, no ads, no watermark. It's one of 161 free browser-based tools at jasperbernaers.com.
