The driving circuit includes a scanning line driving circuit that selects the scanning lines in a predetermined order and a capacitor line driving circuit that selects a first power supply line when a first scanning line is selected and selects a second power supply line when a second scanning line that is spaced predetermined lines away from the first scanning line is selected until the first scanning line is selected again to thereby apply a voltage of the selected one of the power supply lines to the capacitor line, the capacitor line driving circuit applying the voltage of the second power supply line to all the capacitor lines when all the scanning lines are not selected. | 11-27-2008 |
| 20090015570 | ELECTRO-OPTICAL DEVICE, DRIVING CIRCUIT, AND ELECTRONIC APPARATUS - Pixels include liquid crystal capacitors and holding capacitors having first ends connected to pixel electrodes and second ends connected to common electrodes corresponding to the first to 320th rows. A common electrode driving circuit includes TFTs for individual rows. In a partial mode, when a period in which a level of a scanning signal is high is long, a control signal Vg-c is brought to a high level during the period so that the TFTs are turned on. Since gate voltages are applied to the TFTs, a problem in that the gate voltages are reduced due to voltage leakage and the common electrodes are brought into high-impedance states is avoided. Alternatively, potentials of the common electrodes are fixed to a voltage of a common signal, which is a low-level when positive-polarity writing is specified to all the rows and a high-level when negative-polarity writing is specified to all the rows. | 01-15-2009 |
