Grey Scale explained
Grey Scale is the range of shades of grey without any apparent colour.
The darkest possible shade is black, which is the absence of transmitted light or reflected light. The lightest shade is white.
The reason that this is important is that when you have a screen displaying moving content that doesn't have good grey scale, you will have blocks of pixels in one shade of grey only and will loose definition compared to the original image.
It looks complicated, so dont worry about "50 Shade of Grey" at Impact LED Screen all our Vision Screens have a least 642 different shades of grey to ensure you have great image reproduction.
