ABSTRACT:
A method of driving a display having a plurality of light-emitting elements that change with time or use, comprising the steps of: a) displaying first and second image signals having spatially distributed pixels divided into a plurality of groups, and forming first and second image signal group attributes for each of the plurality of groups; b) comparing the second group attributes and the first group attributes to form at least one group difference value for each group, comparing the group difference values to at least one predetermined metric to form at least one pixel group dynamic value, combining the group dynamic values, and if the combined group dynamic values are found to be less than a first limit, displaying a display-preserving image signal over the entire display.
