Abstract:
The present invention is directed to driving methods for a color display device which can display high quality color states. The display device utilizes an electrophoretic fluid which comprises three types of pigment particles having different optical characteristics.

Claim (Index 1):
A driving method for an electrophoretic display comprising a first surface on the viewing side, a second surface on the non-viewing side and an electrophoretic fluid which fluid is sandwiched between a common electrode and a layer of pixel electrodes and comprises a first type of pigment particles, a second type of pigment particles and a third type of pigment particles, all of which are dispersed in a solvent or solvent mixture, wherein\n (a) the three types of pigment particles have optical characteristics differing from one another; (b) the first type of pigment particles and the second type of pigment particles carry opposite charge polarities; and (c) the third type of pigment particles has the same charge polarity as the second type of pigment particles but at a lower intensity, which method comprises the following steps:\n (i) applying a first driving voltage to a pixel in the electrophoretic display for a first period of time, wherein the first driving voltage has a first direction that drives the second type of pigment particles toward the viewing side of the electrophoretic display, wherein the first period of time is not sufficient to drive the pixel to the full color state of the second type of pigment particles at the viewing side; \n (ii) applying a second driving voltage to the pixel for a second period of time, wherein the second driving voltage has a second direction that drives the first type of pigment particles toward the viewing side of the electrophoretic display, wherein the second period of time is not sufficient to drive the pixel to the full color state of the first type of pigment particles at the viewing side; and \n repeating a driving cycle including steps (i) and (ii) for a plurality of times until a color state of a mixture of the first and second types of pigment particles appears at the viewing side.
