Abstract
An electrophoretic device, a driving method thereof, and an electronic apparatus including the same are provided. The electrophoretic device includes a switching element; a latch circuit having an input terminal connected to an output terminal of the switching element; and an electrophoretic element that contains an electrophoretic material between its first and second electrodes, the first electrode being connected to the output terminal of the latch circuit. The method includes a step (a) of supplying a reference potential to the second electrode, turning ON the switching element in synchronization with the supply of the reference potential, and supplying a data signal to the input terminal of the latch circuit, whereby the reference potential or a first potential higher than the reference potential is output from the output terminal of the latch circuit; a step (b) of supplying a driving signal alternating between the reference potential and a second potential higher than the first potential to the second electrode; and a step (c) of supplying the reference potential to the second electrode.
