Electronic Message Centers are a great way to easily change important data from day to day. We offer full design capabilities and technicians to help with any technical questions! An EMC is made up of clusters of three LED bulbs (one red, one green, one blue), called a pixel. Each pixel can create a wide range of colors due to the three different colored bulbs. The distance between each pixel is called a pitch, which determines the resolution of the sign. The closer the pixels are together, the higher the resolution and clarity of the image. It is important to know the distance between the sign and the viewer to determine the ideal pixel pitch for your EMC. The farther away the viewer is from the sign, the lower the resolution needs to be.
