Lines of Characters on a LED Signīecause a space is needed between lines of characters, eight pixel rows are required to display a standard row of characters on a LED sign. The Standard Character MatrixĪ LED sign will utilize a matrix of 7 pixels x 5 pixels to show standard English characters. For example, 16x80 (16 vertical rows by 80 horizontal rows). Electronic LED displays describe the matrix area by the number of pixels vertically by the number of pixels horizontally.
The matrix area is also known as the pixel matrix, which corresponds to the number of pixels that make up the display area. In electronic LED signs, resolution is based on two primary factors, the matrix area and pitch. Resolution is the degree of sharpness and clarity of a displayed image. The matrix of an LED sign determines how many characters will fit on a line, and how many lines will fit on a particular display. Electronic LED signs describe the matrix area by the number of pixels vertically by the number of pixels horizontally. Depending on how coarse or fine the matrix of LEDs, this distance will vary from tens to hundreds of feet. Eventually, your eyes stop paying attention to the display structure and concentrate instead on the images being formed. As you back away from the display, the dots become less noticeable. Viewed up close, they're a jumble of colored dots. This is typical for all LED signs, but some have a wider viewing angle, allowing you to see more of the image.Įstimate one inch of character height for every fifty feet of viewing distance to determine the best character size for your location.Įxample: 2” text is readable to about 100 feet. As you view the LED from different directions, the brightness changes and the image becomes less clear.
When you look at an LED straight on, it is at full brightness. The Viewing Angle refers to the angle from which an LED display is seen by passersby. The closer the pixels (or the tighter the pitch), the crisper and more realistic your image appears, especially when viewed from shorter distances. If a pitch is 16mm, that means that each pixel (or LED cluster) is 16 millimeters apart. The pitch of an LED sign is the distance between each pixel. Arranged in rows and columns, thousands of pixels go into every LED sign. Some pixels are clusters of single colored LEDs the pixels used in color signs combine red, green, and blue LEDs. And light bulbs burn out relatively quickly LEDs can last for over 100,000 hours.īasically, it is as simple as this: a pixel is a cluster of two or more LEDs, each delivering a single point of light or color. LEDs consume far less electricity, requiring only 1/10 to 1/40 the energy of incandescent bulbs. LEDs are much different and far more efficient than incandescent light bulbs.
