Driving method of electrophoretic display device, electrophoretic display device and electronic apparatus

摘要

An image rewriting process includes a first pulse application process for using a driving pulse signal with the pulse width of a first electric potential being a first width; a driving stop process for stopping generation of an electric field between pixel electrodes and a common electrode, performed after the first pulse application process; and a second pulse application process for using the driving pulse signal with the pulse width of the first electric potential being a second width, performed after the driving stop process.

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:
a first phase including a first pulse application process wherein Vcom and Vb have a first logic pulse signal and Va has a second logic pulse signal, said second logic pulse signal being the logic opposite of said first logic pulse signal;a second phase following the first phase, said second phase including a driving stop process wherein Vcom, Va and Vb all have a third logic pulse signal set at a predetermined level to stop the induced electric field between the common electrode and the first pixel electrode; anda third phase following the second phase, said third phase including a second pulse process wherein Vcom and Vb have a fourth logic pulse signal and Va has a fifth logic pulse signal, said fifth logic pulse signal being the logic opposite of said fourth pulse signal.
