1. A method, comprising: identifying, in a display device, an IR voltage drop effect on one pixel of a plurality of pixels supplied by a supply voltage line in the display device, the IR voltage drop based at least in part on currents drawn by other pixels of the plurality of pixels supplied by the supply voltage line; and generating, in the display device, a brightness signal for the one pixel based at least in part on the IR voltage drop effect, wherein the brightness signal compensates for the IR voltage drop effect on the one pixel.
