Abstract
A drive method for a display medium containing two particle types can drive the display medium with a low voltage and thereby achieve high image resolution, downsize the drive circuit, and lower the cost while improving the durability of the display medium. The display medium has a pair of substrates, at least one of which is transparent, disposed with a gap therebetween, and two types of particles of different color and charge characteristics sealed between the pair of substrates. To change the displayed image, the drive method applies a voltage pulse to at least one of the pair of substrates to pull particles that are to move to the substrate to which the particles that are to move adhere, and then applies a voltage pulse to move the particles that are to move to the substrate opposite the substrate to which the particles that are to move adhere.
