Supreme UHD Dimming, a trademark to be licensed in January 2016 by Samsung.
It is a system of local dimming, Samsung TVs used in TV series with 9 SUHD screens on quantum dots.
Although if you analyze what the technology claimed in television sets with screens that do not include the backlight, in principle, as the quantum dots themselves generate light. Yet screens production technology of quantum dot, at this time uses LED backlight.
The very principle of the backlight is reduced to turn off the illumination areas of the screen that provides a black color on the TV screen. The principle of operation of the dimming backlight developed large areas of shade to small areas. Supreme UHD Dimming probably just another improvement dimming technology.
