## Description

The LED Scrolling Text Display Chrome extension offers a full-screen realistic simulation of a dot matrix LED text display for smartphones and tablets. Users can customize the matrix row count, choose from multiple bitmap fonts and sizes, and select the shape and color of LEDs. Features also include adjustable dot size, glow spread, brightness, blinking rates, and multi-directional scrolling with speed control.

Ideal for creating LED scrollers, tickers, banners, or message boards at concerts, parties, or events, this extension supports up to three lines of arbitrary length text. It offers the ability to save and share LED images and animation videos (Android 5+), and manage saved text items with options to play animations or edit settings. The extension also respects user privacy preferences within the European Economic Area by presenting a consent form for ads personalization.
