This is why Daktronics offers dynamic message signs in two viewing angle options&#;focused (15 degrees), wide (30 degrees), and extra-wide (70 degrees)&#;to ensure optimum viewing area. Contact Daktronics, and we'll help you determine what viewing angle could be best for your application.

How do I measure a viewing angle?

Viewing angles are defined as where the intensity of the LEDs are at 50% of their maximum brightness when a traveler is viewing the DMS from a straight position. For example, at 15 degrees off-center, the LED brightness in a standard 30 degree viewing cone would be 50% of the maximum intensity.
