Abstract
A method for driving an electro-optic display having a front electrode, a backplane, and a display medium including at least three differently-colored particles, wherein the medium is positioned between the front electrode and the backplane. The method includes applying a DC balance reset phase to first and second pixel electrodes such that the sum of all impulses results in an offset that maintains a DC-balance across the display medium. The invention additionally includes controllers for executing the method.
