Systems and methods for compensating for IR drop across a display
Abstract:
A display device may include rows of pixels that display image data on a display and a circuit. The circuit may receive pixel data value of image data for a pixel in a first row of the rows of pixels, determine a weight factor to apply to the pixel data value based on a position of the first row with respect to the other rows, such that each row is associated with a current-resistance (IR) drop across the display. The weight factor is determined based on a respective IR drop associated with the first row. The circuit may also generate a weighted pixel data value based on the weight factor and the pixel data value and send the weighted pixel data value to a display driver circuit that renders the image data via the display.
