Using PWM (pulse-width modulation), a technology where the intensity of the LEDs are kept constant but the brightness adjustment is achieved by varying a time interval of flashing these constant light intensity light sources, [26] the backlight is dimmed to the brightest color that appears on the screen while simultaneously boosting the LCD ...

Most LCD screens, however, are built with an internal light source. Such screens consist of several layers. The backlight is usually the first layer from the back. Light valves then vary the amount of light reaching the eye, by blocking its passage in some way. Most use a fixed polarizing filter and a switching one, to block the undesired light.
HDR10+, also known as HDR10 Plus, was announced on 20 April 2017, by Samsung and Amazon Video. HDR10+ updates HDR10 by adding dynamic metadata that can be used to more accurately adjust brightness levels up to the full range of PQ code values (10,000 nits maximum brightness) on a scene-by-scene or frame-by-frame basis.
Display Data Channel (DDC) is a collection of protocols for digital communication between a computer display and a graphics adapter that enable the display to communicate its supported display modes to the adapter and that enable the computer host to adjust monitor parameters, such as brightness and contrast.
It can be used either as a regular adapter to attach USB devices (like flash drives, wired peripherals or the like), or it can be used with Samsung's "Smart Switch" application used to easily transfer data, media and settings from a previous Samsung Galaxy or Android device running Android 4.3 or later, iPhones running iOS 5 or later, or ...
As with overall performance, a lot of other factors influence the length of a battery’s life, including the efficiency of the device as a whole, and the size and brightness of the screen.
Using the controls for gamma, contrast and brightness, the gamma correction on an LCD can only be done for one specific vertical viewing angle, which implies one specific horizontal line on the monitor, at one specific brightness and contrast level. An ICC profile allows one to adjust the monitor for several brightness levels. The quality (and ...
