What is LED Banner?
LED Banner turns your phone, tablet, or laptop screen into a giant scrolling message board. You type the words, choose a colour, size, and motion — static, marquee, typing, pulse, wave, and more — then tap fullscreen and hold the screen up. It is a big text generator, a fullscreen text editor, and a running-text display in one page: the same tool people use for a fan banner at a concert, a name card at airport arrivals, a birthday surprise, a classroom timer message, or a digital sign in a shop window. Everything runs in the browser, so it works offline once loaded and nothing you type is ever uploaded.
How to Use LED Banner
- Type your message in the text box — multiple lines and emoji both work.
- Tap a preset (❤️ I LOVE YOU, 🎉 HAPPY BIRTHDAY, 🔥 LET'S GO…) if you want words and a matching look in one tap.
- Use the Font, Color, and Motion tabs to set size, weight, colour, gradient, neon glow, outline, and animation.
- Leave 'Auto fit to screen' on and the text sizes itself as large as it can go; turn it off to control the size yourself.
- Choose Landscape if you want to hold your phone upright while the words run across the long edge.
- Tap 'Go fullscreen' to hide everything but the banner. Tap the screen to hide the controls, press Esc to come back.
- Use Share or Copy link to send the finished banner to a friend — the link carries every setting.
Examples
Concert fan banner
Input: ENCORE 🎵 · neon cyan on black · Wave · Landscape
Output: Glowing text running across a phone held sideways, readable from the back of a venue
Airport pickup sign
Input: MR. TANAKA · white on black · Static · Auto fit
Output: A name filling the whole screen at maximum size — no printing, no cardboard
Shop window running text
Input: OPEN TODAY UNTIL 10PM — 20% OFF ALL DRINKS · Marquee ←
Output: A continuous scrolling ticker on a spare tablet, at a constant speed no matter the length
Common Mistakes
- Writing a paragraph and expecting stadium-sized letters — auto fit has to shrink text to fit it all, so cut the message to three or four words for maximum size.
- Choosing a marquee animation for a name sign, then wondering why the text keeps leaving the screen; use Static when the words need to be readable continuously.
- Leaving brightness at 100% for a two-hour event and running the battery flat — dim the banner and it is still perfectly readable in a dark venue.
- Picking a dark text colour on a dark background out of habit; a banner is read at distance, so maximum contrast beats subtle colour every time.
- Forgetting to switch off auto-rotate on the phone before holding it sideways — use the tool's Landscape mode instead so the words turn but the phone stays upright.
Why Use This Tool
- One page covers big text, running text, marquee, and fullscreen display instead of four separate tools.
- 14 CSS animations — marquee, typing, pulse, wave, flip and more — each with its own speed control.
- Auto fit sizes every message as large as the screen allows, and re-fits instantly when you rotate or go fullscreen.
- Landscape mode turns the words a quarter-turn so a phone held upright reads across its long edge.
- Neon glow, gradients, outlines, and a brightness control built for dark venues.
- Screen wake lock keeps the display on while the banner is up.
- Shareable links carry every setting, and your last banner is restored automatically from local storage.
- Entirely client-side: nothing you type is uploaded, and it keeps working with no signal once the page has loaded.
