Abstract:
An electronic device may include an electronic display having multiple pixels to display an image based on processed image data. Each of the pixels may include multiple sub-pixels. The electronic device may also include image processing circuitry to receive first image data for a sub-pixel of the and second image data for a group of sub-pixels surrounding the sub-pixel. The first image data may include a luminance value for the sub-pixel and the second image data may include luminance values for each sub-pixel of the group. The image processing circuitry may also determine a compensation value, to compensate the luminance value for lateral current leakage between the sub-pixel and the group of sub-pixels, based on the luminance value of the sub-pixel and the luminance values for each sub-pixel of the group of sub-pixels.
