Patent ID: 8184091

Claim:
A driving method of an electrophoretic display device, the electrophoretic display device including: a pair of substrates; an electrophoretic element which contains electrophoretic particles, the electrophoretic element being interposed between the substrates; a plurality of pixel electrodes located between the electrophoretic element and one substrate of the pair of substrates; and a common electrode which opposes to the plurality of pixel electrodes and is formed at an electrophoretic element side of the other substrate, and the driving method comprising: during an image display period, displaying an image according to image data by inputting potentials, which are determined according to the image data to the plurality of pixel electrodes and inputting a predetermined potential to the common electrode; and during an image maintaining period after the image display period: causing the plurality of pixel electrodes and the common electrode to have the same potential, and causing the plurality of pixel electrodes to fall to a high impedance state and inputting a convergence potential determined according to potential distribution of the pixel electrodes to the common electrode.
