Abstract
There is provided a method for operating an electrophoretic display apparatus including a first substrate; a second substrate; an electrophoretic device being held between the first substrate and the second substrate and containing electrophoretic particles; a first electrode formed on a surface of the first substrate, the surface facing the electrophoretic device; an insulation layer formed between the first electrode and the electrophoretic device; and a second electrode formed on a surface of the second substrate, the surface facing the electrophoretic device. The method includes: (a) driving the electrophoretic device by inputting a first potential to the first electrode and inputting a second potential to the second electrode, and (b) recovering a potential of the second electrode by changing the potential of the second electrode, from the second potential to the first potential, at a constant rate such that a voltage applied to the electrophoretic device is made equal to or smaller than a threshold voltage of the electrophoretic device, wherein (b) is performed after (a) and before next (a).
