About LED Display Units
Unlike traditional media such as newspapers and or magazines, LED displays quickly capture the attention of everyone with the combination of light, color, and motion graphics . LED Displays, also know as electronic message centers are 100% effective. These LED message centers help draw today's on-the-go customers off the streets and straight into your business.
Pixel Design:
The term pixel design is based on a contraction
of pix (Pictures) and el (element). A pixel is the
smallest item of information in a displayed image. A pixel can be one single diode, or a pixel can be a group of lots of diodes running off the same circuit.
Pixel Pitch:
Resolution, or the total number of pixels in a display unit, is very important. It affects the performance of the sign, more resolution means more LED diodes and more circuit, which means sharper picture quality.
Pitch is the distance usually measured in millimeters between each pixel. Pitch is always measured from the center of one pixel to the center of an adjacent pixel.
*Smaller Pitch Number = Higher Resolution / * Larger Pitch Number = Lower Resolution
Viewing Density:
Viewing density and pixel pitch are the two most critical factors to determine the quality of resolution and display brightness. The viewing density of a display is the total number of LED diodes in one square meter. It is calculated by multiplying the number of pixels per square meter by the number of LED diodes per pixel.
Brightness:
The Brightness of an LED display is generally expressed by a numerical value in NITs. A "NIT" is defined as a unit of illuminative brightness described as candela output per square meter (cd/m2). The higher the number of NITs, the brighter the display unit. Industry standards for Indoor Brightness range from 1,500 NITs up to 2,500 NITs. Outdoor standards have much higher nit rating - anywhere from 5,000 - 10,000 NITs.
