Abstract:
1. A driving method of an electrophoretic display device, comprising: providing said electrophoretic display with a display section in which an electrophoretic element including electrophoretic particles is disposed between a pair of substrates, said display section including an arrangement of a plurality of pixels, wherein pixel electrodes address the pixels, said pixel electrodes being formed between one of the substrates and the electrophoretic element, and wherein a common electrode that is coupled to all the pixels and that faces the plurality of pixel electrodes is formed between the other one of the substrates and the electrophoretic element, wherein Va is a first driving pulse signal applied to a first pixel electrode of a first pixel, Vb is a second driving pulse signal applied to a second pixel electrode of a second pixel, and Vcom is a third driving pulse signal applied to the common electrode; rewriting a desired color to the first pixel by applying a three-phase color-changing drive sequence to Va, Vb and Vcom to move the electrophoretic particles of the first pixel by an induced electric field between the common electrode and the first pixel electrode, wherein the three-phase color-changing drive sequence includes:
