Abstract
An ElectroPhoretic Display (EPD) for changing a display is provided. An apparatus having the EPD applies a driving voltage with a periodic pulse to first color particles for a voltage applying period of the first color particles if a current temperature is below a predetermined temperature. The apparatus applies a driving voltage with a pulse that is kept at the same level as applied to second color particles for a voltage applying period of the second color particles. The first color particles have a higher mobility than the second color particles.
