The basic concept of High Dynamic Range new standards is pretty simple : The natural world has a much broader range of color and brightness than current broadcast, Blu-ray, and cinema systems support. For example, just in the simple scenery shown here, brightness ranges from 1 nits for the trunk all the way to 3,000 nits for the sun rays.
Deepsky is changing this. With the ability to render very dark content thanks to the screen black and matt surface, as well as very bright ones, up to 3,000 nits, a display technology has never been so in line with the future HDR standards.
But the complexity in delivering HDR images isn’t only in the ability to render very dark content as well as very bright ones. It is in the ability to control finely each pixel in such a large range of values, from 0 nits and up to 3,000 nits. To say it simply, if an LCD with a brightness range of 1 nits to 500 nits could use only 8 bits of color resolution per sub-pixel, the Dolby Vision and SMPTE teams assessed that you need at least 14 effective bits to range from 0,001 nits to ~ 5,000 nits. If the greyscale resolution doesn’t reach that level, a human eye can see threshold in the video image.
