20090096722 | ELECTROPHORETIC DISPLAY DEVICE, ELECTRONIC APPARATUS, AND METHOD OF DRIVING ELECTROPHORETIC DISPLAY DEVICE - An electrophoretic display device includes a common electrode and a plurality of pixel electrodes, and a disperse system containing electrophoretic particles, that is held between the common electrode and the plurality of pixel electrodes,. The electrophoretic display device includes a switching transistor and a control portion. The switching transistor supplies a corresponding one of the pixel electrodes with a low electric potential signal or a high electric potential signal supplied from a signal line. The control portion controls electric potential signals supplied to the pixel electrode and the common electrode to cause the electrophoretic particles to move. The switching transistor enters an on state when a gate electrode of the switching transistor is supplied with a first electric potential, and enters an off state when the gate electrode is supplied with a second electric potential. The control portion is provided with a first period during which control for causing the electrophoretic particles to move is performed and a second period during which, after the first period, the switching transistor is made to enter an off state. During the second period, when the first electric potential is smaller than the second electric potential, the control portion supplies a low electric potential signal from the signal line to the switching transistor and supplies a low electric potential signal to the common electrode, and when the first electric potential is larger than the second electric potential, the control portion supplies a high electric potential signal from the signal line to the switching transistor and supplies a high electric potential signal to the common electrode. | 04-16-2009 |
20090096773 | ELECTROPHORETIC DISPLAY DEVICE, ELECTRONIC APPARATUS, AND METHOD OF DRIVING ELECTROPHORETIC DISPLAY DEVICE - An electrophoretic display device includes a common electrode and a plurality of pixel electrodes, a disperse system containing electrophoretic particles, the disperse system being held between the common electrode and the plurality of pixel electrodes. The electrophoretic display device includes a switching transistor and a control portion. the switching transistor supplies a corresponding one of the pixel electrodes with a low electric potential signal or a high electric potential signal supplied from a signal line. The control portion controls an electric potential applied between each of the pixel electrodes and the common electrode to cause the electrophoretic particles to move. The control portion provides, in a period during which control for causing the electrophoretic particles to move is performed, a first period during which the switching transistor is held in an on state and a second period during which the switching transistor is held in an off state. The first period continues until charging of the pixel electrode is complete. The second period continues from an end of the first period until movement of the electrophoretic particles is complete. | 04-16-2009 |
