A driving method of an electrophoretic display device, where a first display state and a second display state are respectively selected as a display state of one pixel by applying a voltage with a positive polarity or a negative polarity, and a halftone between the first display state and the second display state is selected according to a total duration of the negative polarity voltage applied to a pixel in the first display state, including setting a display state of the one pixel to the first display state; applying a compensating voltage pulse with the positive polarity to the one pixel; and applying a first driving voltage pulse with the negative polarity to the one pixel; wherein, the applying of the compensating voltage pulse is executed between the setting of the display state and the applying of the first driving voltage pulse.
A driving method of an electrophoretic display device, which has a plurality of pixels where an electrophoretic layer is interposed between a first electrode and a second electrode, and in a case when the potential of the first electrode is higher than the potential of the second electrode, when the potential difference generated between the first electrode and the second electrode is a positive polarity, as a display state of one pixel out of the plurality of pixels, a first display state is selected by applying a voltage with the positive polarity and a second display state is selected by applying a voltage with a negative polarity different from the positive polarity, and a halftone between the first display state and the second display state is selected according to a total duration of the voltage with the negative polarity applied to the one pixel in the first display state, comprising:
A controller for controlling an electrophoretic display device, which has a plurality of pixels where an electrophoretic layer is interposed between a first electrode and a second electrode, and in a case when the potential of the first electrode is higher than the potential of the second electrode, when the potential difference generated between the first electrode and the second electrode is a positive polarity, as a display state of one pixel out of the plurality of pixels, a first display state is selected by applying a voltage with the positive polarity and a second display state is selected by applying a voltage with a negative polarity different from the positive polarity, and a halftone between the first display state and the second display state is selected according to a total duration of the voltage with the negative polarity applied to the one pixel in the first display state, the controller executing a driving method comprising:
