What are the different types of channel letter signs?

Channel letter signs include front-lit, backlit (halo-lit), front and back-lit, open-face, and reverse-lit designs, commonly used for storefronts and commercial branding.

Detailed Breakdown of Types

  1. Front-Lit Channel Letters: LEDs illuminate through the acrylic/polycarbonate face.
  2. Backlit Channel Letters: LEDs create a halo effect behind the letters.
  3. Front and Back-Lit Letters: Dual illumination zones for maximum visibility.
  4. Open-Face Letters: Exposed bulbs for vintage aesthetics.
  5. Reverse-Lit Letters: Light reflects off the mounting surface.

The PDL Sign Pro Tip: Our technicians recommend front and back-lit designs for projects requiring high visibility both day and night.


What are the different types of LED sign boards?

LED sign boards include channel letter signs, box signs, digital displays, edge-lit signs, and neon-style LED signs. Each type serves distinct applications like storefronts, billboards, and reception areas.

LED Board Types Explained

  • Channel Letter Signs: Individual letters lit with LEDs for branding.
  • Box Signs: Enclosed LED panels for illuminated graphics/logos.
  • Digital Displays: Programmable screens for dynamic content.
  • Edge-Lit Signs: LEDs light the edges of acrylic panels.
  • Neon-Style LED Signs: Flexible strips mimic traditional neon.

The PDL Sign Pro Tip: We often suggest edge-lit signs for modern interior branding due to their sleek appearance and cost efficiency.
