Abstract
Various examples are provided for brightness compensation in a display. In one example, a method includes identifying an IR voltage drop effect on a pixel supplied by a supply voltage line and generating a brightness signal for the pixel based at least in part on the IR voltage drop effect. In another example, a method includes calculating values of IR voltage drop corresponding to pixels fed by a common supply voltage line and providing a data line signal to each pixel that compensates for the IR voltage drop. In another example, a display device includes a matrix of pixels and a brightness controller configured to determine an IR voltage drop effect on a pixel of the matrix and generate a brightness signal for the pixel based at least in part on the IR voltage drop effect and a temporal average pixel brightness within one refreshing cycle associated with the pixel.
