backlight linearly affects energy footprint. Intel DPST technology aims to adaptively reduce backlight brightness while maintaining satisfactory visual performance. The Intel DPST subsystem analyzes the image to be displayed and it uses a set of algorithms to change the

Brightness is an attribute of visual perception in which a source appears to be radiating or reflecting light. In other words, brightness is the perception elicited by the luminance of a visual target. The perception is not linear to luminance, ...
