A first display (100) comprises a layer of electro-optic material (112) with first and second electrodes (110, 116) on opposed sides thereof, one or both electrodes (110, 116) having at least two spaced contacts (T1-T4, B1-B4), and voltage control means are arranged to vary the potential difference between the two spaced contacts (T1-T4, B1-B4) attached to the same electrode. A second display (600) comprises a layer of electro-optic material (610) with a sequence of at least three electrodes (612-624) adjacent thereto. Voltage control means (626) vary the potential difference between the first and last electrodes (612, 624) of the sequence. The electrodes (612-624) of the sequence alternate between the two surfaces of the layer of electro-optic material (610), and have edges which overlap with or lie adjacent the preceding and following electrodes of the sequence. The electrodes, other than the first and last, are electrically isolated such that the potential thereof is controlled by passage of current through the layer of electro-optic material (610). Methods for driving these displays are also provided |
