Abstract:
1. A display apparatus, comprising: a first substrate upon which is situated a closed container; first and second charged particles which are held in the closed container and have mutually different charge polarities and a substantially identical color; and first, second and third electrodes for generating an electric field in the closed container wherein the second and third electrodes are substantially the same size and the first electrode is larger than the second and third electrodes, with the first electrode being disposed on the first substrate and with the second and third electrodes being disposed on opposite sides of the closed container and perpendicular to or across from the first electrode; wherein said display apparatus successively and alternately executes a first display operation and a second display operation, wherein in the first display operation, the first charged particles are collected on the first electrode by applying a first display voltage to the first electrode, a second display voltage to the second electrode and a third display voltage to the third electrode, wherein at least one of the second and third display voltages is a ground voltage, after a first reset operation in which the first and second charged particles are collected on the second electrode and on the third electrode by applying a first reset voltage to the first electrode, a second reset voltage to the second electrode and a third reset voltage to the third electrode wherein the second reset voltage and the third reset voltage have substantially equal magnitude and opposite polarity, and wherein in the second display operation, the second charged particles are collected on the first electrode by applying a fourth display voltage to the first electrode and by applying a fifth display voltage to the second electrode and a sixth display voltage to the third electrode, wherein at least one of the fifth and sixth display voltages is a ground voltage, after a second reset operation in which the first and second charged particles are collected on the second electrode and on the third electrode by applying a fourth reset voltage to the first electrode, and by applying a fifth reset voltage to the second electrode and a sixth reset voltage to the third electrode, wherein the fifth reset voltage and the sixth reset voltage are, respectively, of substantially equal magnitude and opposite in polarity to the second reset voltage and the third reset voltage applied in the first reset operation.
