Multiplexed driving method for an electrooptical device, and circuit therefor |
摘要 |
A driving method is provided for an electrooptical device having scanning and signal electrodes arranged in a matrix with a plurality of picture elements formed in association with intersections of the electrodes. Voltages of high-frequency pulses are applied to both the scanning and signal electrodes, and a DC voltage pulse for setting the optical state of the electrooptical material is applied to the picture elements during a selected period for the scanning electrodes, while a high-frequency AC voltage for holding the previously set optical state of the electrooptical material is applied to the picture elements during a non-selected period for the scanning electrodes. A circuit is also provided for carrying out the method, and an electrooptical apparatus is provided employing the electrooptical device described above.
