Phosphor Display

Phosphor simulates a physical LED dot-matrix display on your screen. Send text, images, and animations to a virtual LED panel with authentic phosphor glow, dome highlights, and other visual effects.

Control the display over your local network via a built-in HTTP API, or use the web admin panel from any browser on the same network. Supports scrolling text, static images, GIF playback, clock mode, and several generative animations.

• Metal-based SDF renderer with per-dot glow
• Full RGB per-pixel grid control
• 12 visual effect toggles (phosphor persistence, scanlines, CRT curvature, and more)
• Built-in web admin panel with image upload
• HTTP API for local network automation
• Clock mode
• Generative animations: rain, plasma, Game of Life, matrix, bouncing dot
