Abstract
Variation in IR drop across the electronic display may result in display pixels that are intended to be programmed with the same image data to behave differently, resulting in visible image artifacts. The current drawn by the intensity of the display pixels displaying an aggressor image may cause a voltage (IR) drop across a non-aggressing (or victim) portion of the display. This IR drop across the electronic display may result in a visible image artifact, such as a transition band across the non-aggressing portion of the electronic display. To reduce or eliminate image artifacts, IR drop compensation may be provided to the electronic display. The IR drop compensation may be determined on a per-zone basis based on present frame average pixel luminance (APL), previous frame APL, and IR drop due to each respective zone in a plurality of zones across the electronic display.
