LED Sign Terminology
LED Sign Display systems give you a tremendous flexibility in how you engage a viewer, but there are a few important considerations to keep in mind when you are designing a sign. How you orient it, and how you design the content for it are just as important as the manufacturing specifications you choose for your sign. No matter how good your sign and the content you have placed on it, if an end user can’t see or read it, it won’t do a thing to help your business.

If the target audience is moving, then another factor, time, is required. Based on Surefire Sign experience and research, an average of at least three to four seconds is required for a moving audience to adequately recognize and comprehend six to eight grouping of content on an electronic sign. The following chart lists the maximum time an audience will have to view an electronic sign with specific characters size. For example, an audience will have three seconds or less to view electronic signs with four inches of text. If the electronic signs have too much content, than the reader will not have sufficient time to comprehend the entire content.

Viewing distances are calculated based on the display type and the distance from the display. Each display will have a minimum and a maximum viewing distance that may vary based on application and intended use.
For example, a large character will have a longer viewing distance while a small character will have a shorter viewing distance. Surefire Sign uses 50 feet for every one inch of character distance as a general point of reference.
What are Viewing Angles?
Viewing Angle Diagram
LED displays are at their brightest when viewed “head on” and slowly decrease in brightness as the viewing angle increases.
The viewing angles of an LED display – both horizontal and vertical – are the angles at which the intensity has dropped 50 percent from the direct “head on” brightness.
