CHOOSING A SIGN
Pixel Pitch & Viewing Distance
One of the most important decisions when purchasing an LED Electronic Message Center (EMC) is determining the appropriate resolution (pixel pitch) and physical size. These are influenced by several factors including how the sign will be used, where it will be placed, distance to the audience and the speed of the audience to name a few. Please speak with your authorized EBSCO dealer partner to better understand which display is suitable for your application.
The recommended minimum and maximum viewing distances of an EMC are based on two characteristics of the display: The pixel pitch and the display’s physical size.
LED EMC Display Recommended Viewing Distances:
Use these calculations to help you select the best size and pixel pitch for your specific location.
Minimum: Pixel Pitch is the distance from the center of one pixel to the center of the adjacent pixel. An EMCs minimum viewing distance is driven by this measurement. If the EMC is viewed at a distance closer than the “Minimum”, messages will still be readable, but will appear pixelated.
10mm Pixel Pitch = 10 Meters (~33 ft)
p>16mm Pixel Pitch = 16 Meters (~52 ft)
p>20mm Pixel Pitch= 20 Meters (~65 ft)
p>26.6mm Pixel Pitch= 26 Meters (~87 ft)
Maximum: The practical maximum distance a sign can be seen from is 10 times the sign’s square footage. Any viewing distance greater than this calculation will decrease the readability of the sign and its ability to attract attention. For example: 4′ x 6′ sign = 24 square feet so 24 x 10 = 240 feet
