Abstract: A light emitting diode (LED) display can calculate a common voltage charge of a line of pixels in the LED display, the common voltage charge comprising a difference between a first line of pixels and a second line of pixels. If the calculated common voltage charge exceeds a predetermined threshold, a toggle matrix can be generated for the line of pixels. The toggle matrix can include a matrix of charge values generated by calculating a difference in charge values for each subpixel a first line of subpixels with each subpixel a second line of subpixels. The LED display can identify one or more regions of subpixels exhibiting the predetermined toggle pattern in the toggle matrix. The LED display can generate a voltage correction charge to apply to affected regions of the display. Alternatively, the subpixels or pixels could be swapped with adjacent pixels to reduce toggling or settling error.
