People call them all kinds of names: electronic message centers, digital displays, reader boards and electronic signs, just to name a few. At Arrow Sign, we keep it simple: We call them "outdoor LED signs" regardless of size or placement. And we want you to be comfortable knowing whether an LED sign is right for your business or organization. The more you know, the surer you'll be that you've made the right decision.

LED Signs 101

For starters, LED Stands For …

Light Emitting Diode. An LED is not a light bulb, but an efficient, effective, ultrabright alternative that doesn't burn out.

Our View on Viewing Angle

Viewing Angle is the angle at which the LEDs brightness is halved. An LED is at full brightness when you look at it straight on or dead center. If that level of brightness is halved by moving 70° from dead center, the viewing angle is considered to be double that number, or 140°.

Reading Angle is the angle at which a people can adequately read your LED message, and, while typically greater than the viewing angle, it varies depending on lighting circumstances and a sign's environment.

Typical LED displays will give you a viewing angle of up to a 140° horizontal (off to either side) x 70° vertical (looking up or down at the sign), which is easily among the best in the outdoor sign industry.

Color vs. Monochrome

Monochrome LED signs have long set the standard for effective outdoor signage and are a proven way to get results. They're particularly effective if you have a simple, text-driven message you'd like to customize from time to time.

But if you have a product you'd like to show in all its splendor, or if you'd like to play snippets of videos or animation and take advantage of other advertising tactics previously only available on TV and online, you might want to consider a color LED sign.

What is Pixel Pitch?

Pixel pitch is the distance between each pixel on your sign. A pixel is a cluster of typically three LEDs - one red, one green and one blue. The closer the pixels, the crisper and more life-like your image will be. For instance, our sharpest and highest resolution option is 12mm, which means each pixel is a mere 12 millimeters apart.
