Abstract:
A driving method for driving an electrophoretic display comprising four types of particles, the first type of particles and the third type of particles are positively charged, and the second type of particles and the fourth type of particles are negatively charged, the method comprises the steps of: (i). applying a first driving voltage to the pixel of the electrophoretic display for a first period of time at a first amplitude to drive the pixel to a color state of the fourth type of particle at the viewing side; and (ii). applying a second driving voltage to the pixel of the electrophoretic display for a second period of time, opposite to that of the first driving voltage and a second amplitude smaller than that of the first amplitude, to drive the second type particle towards the non-viewing side.
