A method of controlling a passive matrix display having rows and columns of pixels including receiving an input image signal; determining drive signals for at least a first image field and a second image field; calculating a value that is correlated to a change in the total capacitive charge of the pixels that will occur between the display of the first image field and the second image field for at least one column of the passive-matrix, electro-luminescent display; adjusting at least one of the drive signals within first or second image fields to compensate for the change in total capacitive charge; and providing adjusted drive signals for each pixel.
