Abstract: Systems and methods described herein may utilize a non-linear scaling relationship to scale brightness of selective portions of the display in a manner that reduces or eliminates perceivable banding effects. By non-linearly controlling changes in brightness of the display, a viewer may perceive a more uniform, linear dimming towards the relatively dimmer region without perceiving banding, leading to improved user experience when viewing the electronic display.
