Claim 10:
11. A method of driving an electro-optic display comprising a layer of electro-optic material disposed between a top electrode and a backplane, the backplane including an array of pixel electrodes, wherein each pixel electrode is coupled to a thin film transistor (TFT) and a storage capacitor, the TFT including a source, a gate, and a drain, wherein the gate is coupled to a gate line, the source is coupled to a scan line, and the drain is coupled to the pixel electrode, wherein a controller provides time-dependent voltages to the gate line, the scan line, the top electrode, and the storage capacitor, wherein a first side of the storage capacitor is coupled to the pixel electrode and a second side of the storage capacitor is coupled to the controller, the method of driving comprising (in order):
a) providing a first high voltage to the scan line and a first low voltage to the top electrode and the second side of the storage capacitor;
b) providing a first gate pulse sufficient to open the TFT;
c) after the first gate pulse, providing a second low voltage to the scan line;
d) providing a second gate pulse sufficient to open the TFT;
e) after the second gate pulse, providing a second high voltage to the top electrode and the second side of the storage capacitor; and
f) providing a third gate pulse sufficient to open the TFT.
