Abstract:
1. 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: applying a first driving voltage, at a first voltage level, with a periodic pulse, to a common electrode, which moves the first color particles toward the surface of the EPD, 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 a mobility of the second color particles; and applying a second driving voltage, at a second voltage level different from the first voltage level, to the common electrode, which moves the second color particles toward the surface of the EPD, throughout a voltage applying period of the second color particles, wherein the voltage applying period of the first color particles and the voltage applying period of the second color particles are equal, and the voltage applying period of the first color particles and the voltage applying period of the second color particles are adjacent.
