Title:
DRIVING METHOD OF ELECTROPHORETIC DISPLAY, AND ELECTROPHORETIC DISPLAY
Document Type and Number:
Japanese Patent JP2011013414
Kind Code:
A
Abstract:

To provide a driving method of an electrophoretic display by which response speed of switching from a first display state to a second display state is high and unevenness is eliminated in display in the electrophoretic display and to provide the electrophoretic display controlled by the driving method of the electrophoretic display.

In the electrophoretic display including an electrophoretic display medium wherein three kinds of particles having optical characteristics and charge characteristics different from each other are dispersed in a solvent between a first transparent electrode and second and third transparent electrodes, when switching is performed from a first display state displaying a color to a second display state displaying a color different from that of the first display state, initialization driving including a first voltage applying step of repeating a voltage applying pattern made of a prescribed rectangular wave to the second electrode once or a plurality of times and a second voltage applying step of repeating a voltage applying pattern made of a prescribed rectangular wave to the third electrode once or a plurality of times is performed before the second display state is displayed.
