The digital signage industry has a fairly specific set of terms and jargon for describing LED displays. Here is a quick layman's guide to some of the most important terms to know when learning about digital signage.
Display processing - This is simply the technical term for the process by which the digital sign takes a digital image and converts it into a visible display on the sign.
Full motion display processing - Digital signage displays, which are capable of video playback, utilize "full motion" display processing, meaning it can create smooth and seamless video.
Case Configuration - This describes what materials the LED's case is made from, and other features such as how weather-resistant it is.
Pixel - A "pixel" is simply a single "dot" on the display that can be as small as one LED or it may contain a cluster of LEDs that act as a unit. An LED display is made up of an array of pixels.
Pixel Pitch - the distance from the center of one pixel to the center of the adjacent pixel. This is equivalent to a display’s resolution and is commonly measured in millimeters. The larger this number is the more spacing there is between pixels which result in a lower resolution. The lower this number is, the more tightly the pixels are packed together resulting in a higher resolution.
Optimal Viewing Angle - There is a point where a digital sign becomes too dim to see if you are too far to one side of it. When this happens, you are outside the Optimal Viewing Angle. The wider the OVA, the better for visibility.
Color processing - How many colors a display is capable of. Most full-color displays can display more than 250 trillion shades.
Frame rate (FPS) - The frame rate indicates how many times per second the image is updated. This is measured in frames per second, or FPS. The higher the FPS, the smoother the video appears.
Operating Temp - LED displays can operate in a wide range of temperatures, generally from around -40°F up to around 120°F, allowing them to work in most environments.
Brightness - The brightness of a LED display is measured in units called "nits." One nit is roughly equivalent to a single burning candle. LED displays are capable of brightness measured in several thousands of nits.
Software (Content Management Software) - Every digital sign requires computer software, which allows you to manage messages, pick graphics, and schedule message changeover times.
Full color LED display - A digital signage display that can display the full range of colors, by using a matrix of three colored subpixels that, when lit in different combinations and intensities, can create the full spectrum.
Monochrome LED display - A LED display that only displays one color, generally either red or amber, which are generally used for text-only displays.
