METHOD FOR DRIVING ELECTROPHORETIC DISPLAY DEVICE, ELECTROPHORETIC DISPLAY DEVICE, ELECTRONIC EQUIPMENT AND ELECTRONIC CLOCK

摘要

PROBLEM TO BE SOLVED: To provide a method for driving an electrophoretic display device for preventing local decrease in a contrast ratio or generation of afterimage while maintaining a DC balance.

SOLUTION: The driving method comprises: a first image display step (S2) of displaying a first image in a first color in a display unit by a partial drive system that comprises applying a voltage based on a drive pulse signal to a common electrode, applying a voltage to each of a plurality of pixel electrodes based on an inverted signal or a normal signal of a drive pulse signal to rewrite an image to be displayed in the display unit; a first image erase step (S4) of subsequently displaying the background of the first image by use of the first color in the display unit by the partial drive system; a second image display step (S6) of subsequently displaying the background of a second image by use of a second color in the display unit by the partial drive system; and a second image erase step (S8) of subsequently displaying the second image in the second color in the display unit by the partial drive system. The next first image display step is carried out after the second image erase step.
