Choosing The Right Type Of Digital Sign

Choosing The Right Type of Digital Sign – Speech from Buddy Swisshelm

Choosing the right type of digital sign is one of the most important decisions a business or organization can make—and it’s not always as simple as it seems. The technology, specifications, and performance differences between digital signs can dramatically impact visibility, quality, and long-term return on investment.

That’s why specialized knowledge and experience matter. Today’s guest speaker, Buddy Swisshelm, is one of the nation’s top professionals in the digital signage industry. With decades of experience in outdoor advertising and LED display technology, Buddy has helped countless businesses, churches, and municipalities make informed decisions about their signage investments.

In this presentation, Buddy will break down the key differences between 6mm, 10mm, and 16mm digital signs—explaining not just what those numbers mean, but how they affect clarity, brightness, and overall impact. His insights will help you understand how to choose the right sign for your location, your audience, and your budget.

6MM vs. 10MM vs. 16MM Digital Signs: What You Need to Know

In the early 2000s, digital signage began emerging across the United States as a powerful advertising tool. The first-generation displays—known as DIP (Dual In-Line Package) models—used three diodes (red, green, and blue) to form each pixel, earning the nickname “RGB displays.” These early signs had a 36mm pixel pitch, which refers to the distance between each pixel.

As the technology evolved, pixel spacing became smaller—moving from 36mm to 28mm, 23mm, 20mm, and eventually 16mm, which became the most widely adopted format in the U.S.

Why the Global Market Shifted to 10MM

While 16mm remained dominant in the U.S., international markets quickly transitioned to 10mm for two key reasons:

Closer Viewing Distance – In Europe and Asia, businesses are typically located closer to roads, requiring signs that are sharper and more readable up close.
Brightness Degradation – DIP models had a major drawback: a 30% brightness loss over five years. When a module was replaced, the new one was significantly brighter, creating a patchy, checkerboard effect.

To resolve this, manufacturers developed a new pixel type called SMD (Surface Mounted Diode). SMD technology eliminated the brightness drop-off, offering consistent appearance even when individual modules were replaced. However, SMD was primarily developed for 10mm and lower pixel pitches; only a few manufacturers adapted it to 16mm due to the high cost of retooling.

By 2018, 10mm became the new standard in the U.S. due to its superior appearance and reliable brightness.

Enter the 6MM: A Game-Changer

In 2020, lower-pitch displays—8mm and 6mm—were introduced in the U.S. These formats had already taken over the international market and were the highlight at global signage expos and conventions. With significantly sharper graphics and increased brightness, they quickly became preferred.

However, the industry still faced one issue: heat buildup. Traditional black-frame modules retained heat, accelerating component failure (modules, power supplies, and data ribbons). Fans and even white-frame alternatives offered some relief, but they didn’t eliminate the problem.

During COVID, major manufacturers addressed this with a redesigned open-back cabinet that significantly reduced internal temperature. These new cabinets were water-tight and demonstrated their durability by being displayed submerged in water. Additionally, manufacturers upgraded internal wiring from copper to gold, improving both color quality and electrical conductivity.

This cutting-edge technology was rolled out in 8mm and 6mm products, as they were already dominating international markets. Side-by-side, the 6mm vastly outperformed the 10mm in clarity and color—making the 10mm obsolete for many buyers.

Pixel Density Comparison (Per Side of a 12×32 Sign):

16mm – 98,304 pixels
10mm – 393,216 pixels
6mm – 884,736 pixels

The visual difference is dramatic. The 6mm not only delivers the sharpest image, but its modern cabinet design and gold wiring also enhance performance and longevity. It’s now the preferred choice for most digital billboard projects.

Market Trends and Local Installations

Since 2020, I have not sold a single 10mm, and I haven’t sold a 16mm display in over 8 years. Most of the 100+ references I provided are 6mm installations, including:

On-Premise 6MM Installs (Local):

Many commercial sites across Western Pennsylvania

Billboard 6MM Installs:

7205 US-22, Greensburg, PA – 12×25
6515 State Route 22, Delmont, PA – 10×31 and 12×24 vertical
Eight Billboards east of Pittsburgh in Altoona, Huntingdon, Lewistown, and Burnham, PA
Four New 6MM Billboard Projects coming soon in Lower Burrell, Perryopolis, West Mifflin, and Franklin, PA

Final Thoughts

While you may not have a 10mm or 16mm display next to a 6mm for direct comparison, the differences are clear:

Sharper visuals
Higher brightness (up to 10,000 nits)
Modern cabinet design
Gold wiring for improved quality
No checkerboard brightness issues

The 6MM is the best long-term investment. That said, if budget is a concern, 10MM is still available and may save you approximately $50 per square foot.

Let me know if you have any additional questions—I’d be happy to assist further.
