Electrode arrays for cellular displays
First Claim
1. A method for driving electrophoretic cellular display device comprising,applying a periodic voltage signal to a common electrode of an electrophoretic cellular display device, said periodic voltage signal having a low voltage and a high voltage, andsetting each cell electrode of said display device to one of two cell state non-periodic DC voltages, one of said voltages being near the low voltage of said periodic voltage signal, the other of said voltages being near the high voltage of said periodic voltage signal.

Abstract
An electric flat panel display has a matrix of flat panel display cells and a fault tolerant driver circuit and an electrode array. A folded field drive scheme applies a periodic voltage signal to a common electrode. Opposing electrodes are set to one of two voltage states by voltage setting circuits.
