The highlights—the brightest parts of an image—can be brighter, more colorful, and more detailed. [2] The larger capacity for brightness can be used to increase the brightness of small areas without increasing the overall image's brightness, resulting in, for example, bright reflections from shiny objects, bright stars in a dark night scene, and bright and colorful light-emissive objects ...

A widespread practical application is using quantum dot enhancement film (QDEF) layer to improve the LED backlighting in LCD TVs.Light from a blue LED backlight is converted by QDs to relatively pure red and green, so that this combination of blue, green and red light incurs less blue-green crosstalk and light absorption in the color filters after the LCD screen, thereby increasing useful ...
Newer HD TVs have a default setting that can make watching sports or other live TV look nice and smooth. It’s called “motion smoothing” or “motion interpolation,” and it smooths out fast ...
Since a larger color space increases the difference between colors, an increase of 1 bit per sample is needed for Rec. 2020 to equal or exceed the color precision of Rec. 709. [12] The NHK measured contrast sensitivity for the Rec. 2020 color space using Barten's equation which had previously been used to determine the bit depth for digital cinema.
The aim of color calibration is to measure and/or adjust the color response of a device (input or output) to a known state. [1] In International Color Consortium (ICC) terms, this is the basis for an additional color characterization of the device and later profiling. [ 2 ]

Varies based on image brightness and color. For the majority of images it will consume 60–80% of the power of an LCD. OLED displays use 40% of the power of an LCD displaying an image that is primarily black as they lack the need for a backlight , [ 35 ] while OLED can use more than three times as much power to display a mostly white image ...
