LED Displays and Color Calibration All information contained within is property of NanoLumens. All rights reserved. 1 Introduction LED Displays have come of age. As companies turn to digital signage for their messaging, competition in the industry has become more aggressive. Before making an investment decision there are several key questions buyers should ask: Are the LED displays available in any size, shape or curvature? This is important if space is limited or challenging. Is the color evenly distributed? It is normal for an LED to degrade in color over time, but the display color should remain constant across the screen. With the use of color calibration at NanoLumens, all displays are guaranteed to be the best quality. Why Expert Color Calibration Is Needed LED displays are organized in an array format. Some arrangements can be found in rows and columns, and others by blocks. This is because LED manufacturers create and produce LEDs by grouping them through a process called binning. When an LED manufacturer bins LEDs, they group them by their common qualities -- usually by light intensity and color wavelength. However, when a display combines multiple "bins" of LEDs, each bin will have a different quality. Individual bins will be relatively consistent, but as a whole, the display will look blotchy. "Many times, batches of LEDs can be faulty and show obvious signs of color variation." says Rick Morrison, Senior Electrical Engineer at NanoLumens. The result is an LED display that looks sloppy and unmatched. Displays that have not been calibrated can be quite noticeable even to the untrained eye, often resulting in a poorly color-distributed display. LED Displays – Constantly Changing and Improving
