Driving method for optical modulation device |
摘要 |
An optical modulation device includes scanning electrodes and signal electrodes disposed opposite to and intersecting with the signal electrodes, and an optical modulation material disposed between the electrodes, a pixel being formed at each intersection of the electrodes so as to provide a matrix of pixels as a whole and having a contrast depending on the polarity of a voltage applied thereto. The device is driven by a method including, in a writing period for writing in the respective pixels on a selected scanning electrode: at least two repeating sets of phases, each set of phases comprising a state-determining phase for determining the contrast of a pixel and an auxiliary phase for not determining the contrast of the pixel.
