HDR and Wide Color Gamut

With pixel resolution mostly solved, the industry has moved onto the next problem: how to make better pixels. Over the last few years, manufacturers, content creators and standards bodies have been working on improving the other two main parts of an image: contrast ratio (dynamic range) and color space (gamut). Combined, these two innovations allow for a significantly greater picture, one that is significantly noticeable by viewers. The resulting two technologies that manufacturers will promote during the next few years are high dynamic range (HDR) and wide color gamut (WCG).
HDR: Killer contrast
Dynamic range, in this context, is what most refer to as contrast ratio. Contrast ratio, in layman's terms, is the ratio between the brightest whites and the darkest blacks a display can reproduce. Despite marketing hype, a 100:1 contrast ratio, particularly on a projection system, is a very, very good image in today's video world.
However, humans can see far beyond a 10,000:1 contrast ratio, and HDR will get many displays much closer to that level. This is a very promising development because the human eye is very sensitive to changes in contrast due to the anatomical structure of the eye.



Wide Color Gamut: 50 percent more hues
High dynamic range alone is enough to be extremely bullish about the new wave of displays hitting the market. However, it's only half of the equation. The other half of the equation is in the color that a display can reproduce. Most displays today use an ITU (International Telecommunications Union) standard called rec.709, which standardizes the maximum values of the primary colors: red, blue and green and any colors in between.
