Patent ID: 7982710

Claim:
A driving device for an image display medium that drives the image display medium comprising: a display substrate having at least translucency; a back surface substrate facing the display substrate with a gap therebetween; a plurality of first electrodes arranged in parallel along a predetermined direction; a plurality of second electrodes arranged facing the first electrodes; and particles enclosed between the display substrate and the back surface substrate so as to move according to an electric field generated between the display substrate and the back surface substrate by applying a voltage corresponding to an image between the first electrode and the second electrode; the driving device comprising: a voltage application section that applies the voltage corresponding to an image between the first electrode and the second electrode, wherein the voltage application section, as a display drive voltage to be applied for each pixel to display a desired color at each pixel, applies a first pulse voltage configured to cause the particles in a stationary state to start moving and immediately after application of the first pulse voltage, applies a second pulse voltage that can cause the particles that have started moving to move, the first pulse voltage consists of a single pulse, and the second pulse voltage consists of a plurality of pulses that alternately have a positive value and a negative value of a same absolute amount, with each pulse also having a same width.
