DRIVING METHOD OF LIQUID CRYSTAL ELEMENT

摘要

PURPOSE:To execute display of a large image screen at a high speed by impressing a scanning signal to the gates of the FETs corresponding to respective picture elements and prescribed display signals to selected counter electrodes to execute writing and impressing the prescribed display signals to another selected counter electrodes to execute writing. CONSTITUTION:A ferroelectric liquid crystal having a bistable state is held in place between a substrate provided with picture element electrodes corresponding to the FETs and a substrate provided with the counter electrodes, by which a liquid crystal element is constituted. The counter electrodes of the FETs constituting the active matrix are connected to display electrodes 7 and the gates are connected to scanning electrodes 6. The sources or drains are grounded. The prescribed scanning signal is impressed to the electrodes 6 and the prescribed display signals are impressed to the selected electrodes 7 to write the display state based on the 1st orientation state of the liquid crystal and the prescribed display signals are impressed to another selected electrodes 7 to write the display state based on the 2nd orientation state, by which the time dividing driving is executed. The display of the large screen image with a large number of the picture elements and at the high speed is thus executed.
