Patent ID: 8648795

Claim:
A method for driving a display sheet having a display layer having storage portions storing positively or negatively charged first particles and second particles that are charged with polarity opposite to that of the first particles and have color whose light reflectance is lower than that of the first particles, the method comprising: displaying a desired image on the display surface provided at the one surface of the display layer by causing an electric field to act on the storage portions so that the storage portions achieves a first display state in which the second particles are unevenly present at one surface of the display layer and the first particles are dispersed in the storage portion or a second display state in which the second particles are unevenly present at the other surface of the display layer and the first particles are dispersed in the storage portion; and driving the display sheet in such a manner as to provide, when switching a first image displayed on the display surface to a second image different from the first image, a reset period for causing a resetting electric field for achieving the second display state to act at least on the storage portions in the first display state among the storage portions prior to causing an electric field for displaying the second image to act on the storage portions, the reset period having a first period in which the second particles are moved to the one surface and also the first particles are moved to the other surface and a second period, after the first period, in which the first particles are moved to the one surface and also the second particles are moved to the other surface.
