Abstract
An electrophoretic display device driving method includes: applying a first voltage between a first electrode and a common electrode to display a highest or lowest gray scale at a first pixel, subsequently applying a second voltage between a second electrode and the common electrode to display an intermediate gray scale at a second pixel, and subsequently applying a third voltage between a third electrode and the common electrode to display the other of the highest and lowest gray scale at a third pixel; then, with each electrode in a high-impedance state, applying a first auxiliary voltage between one of the first and third electrodes and the common electrode; and thereafter, applying a second auxiliary voltage between the other of the first and third electrode and the common electrode, the second electrode is in the high-impedance state while the auxiliary voltages are applied to the first and third electrodes.
