Patent ID: 8890800

Claim:
A driving method of an electrophoretic display device comprising: the electrophoretic display device comprising: a display section that comprises an electrophoretic element including electrophoretic particles; a plurality of pixel electrodes disposed on a first side of the electrophoretic element; a common electrode disposed on a second side of the electrophoretic element; wherein the electrophoretic particles include a first electrophoretic particle that displays a first color and a second electrophoretic particle that displays a second color; the method comprising: drawing an image on the display section by applying a voltage based on a driving pulse signal that repeats a first electric potential and a second electric potential to the common electrode, and by applying any one of the first electric potential, the second electric potential and the voltage based on the driving pulse signal to each of the plurality of pixel electrodes, wherein the drawing comprises: applying a first pulse signal of the driving pulse signal with the pulse width of the first electric potential being a first width; applying a second pulse signal of the driving pulse signal with the pulse width of the first electric potential being a second width longer than the first width, after applying the first pulse signal; and applying a third pulse signal of the driving pulse signal with the pulse width of the first electric potential being a third width shorter than the second width, successively to applying the second pulse signal; wherein, applying the third pulse signal, comprises (i) applying the third pulse signal to display the first color to terminate driving of the common electrode in a case in which the diameter of the second electrophoretic particle is larger than the diameter of the first electrophoretic particle, and (ii) applying the third pulse signal to display the second color to terminate driving of the common electrode in a case in which the diameter of the second electrophoretic particle is smaller than the diameter of the first electrophoretic particle.
