Abstract
We describe circuits and methods for compensating for gate kickback in electro-optic displays, in particular electrophoretic displays. In embodiments the method comprises compensating gate kickback comprising a change in voltage between a pixel electrode and a common electrode of the display arising from capacitive coupling between a gate drive line and the pixel electrode by offsetting a value of a common voltage on the common electrode by an offset value dependent on a difference between a magnitude of said positive gate voltage and a magnitude of said negative gate voltage.
