Some pixels are clusters of single colored Led’s; the pixels used in color signs combine red, green, and blue Led’s. Arranged in rows and columns, thousands of pixels go into every sign. Quality of an LED sign is determined by its pitch. The pitch of an LED sign is the distance between each pixel. The closer the pixels  the crisper and more realistic your image appears. The LED viewing angle refers to the angle at which you view a sign. When you look at an LED straight on, it is at full brightness. As you view the LED from different directions, the brightness changes. This is typical for all LED signs, but some have a wider viewing angle, allowing you to see more of the image .Monochrome (single color) LED signs have been around a long time.
