Patent ID: 8531390

Claim:
A method of driving an ElectroPhoretic Display (EPD) so that a device having the EPD including first color particles and second color particles changes a display as an electrophoresis element, the method comprising the steps of: applying a driving voltage with a periodic pulse to the first color particles for a voltage applying period of the first color particles, when a current temperature is below a predetermined temperature, wherein the first color particles have a higher mobility than the second color particles; applying a driving voltage with a pulse that is kept at the same level as applied to the second color particles for a voltage applying period of the second color particles; and applying the driving voltage with the pulse that is kept at the same level to the first color particles when the current temperature is higher than the predetermined temperature, wherein the voltage applying period of the first color particles and the voltage applying period of the second color particles are equal, and a pulse rate of the periodic pulse is determined in accordance with a difference in mobility between the first color particles and the second color particles at the predetermined temperature.
