Abstract

A system and method for estimating and using pixel compensation coefficients. In some embodiments, the method includes, during a first time interval: comparing a first pixel current for a pixel of the display with a first reference current, to obtain a first pixel current error signal, the first pixel current error signal being the sign of a difference between the first pixel current and the first reference current; and updating one or more compensation coefficients for the pixel, based on the first pixel current error signal.
