Document Type and Number:
Japanese Patent JP2977356
Kind Code:
B2
Abstract:
A method of driving an active-matrix liquid-crystal display device including switching elements connected to scan lines and data lines, and pixel electrodes for applying an electric field to a liquid (1A, 2A, 1B, 2B) with the aid of the switching elements, the switching elements and the pixel electrodes being arrayed in a matrix, and the liquid crystal being composed of a liquid crystal with spontaneous polarization includes the steps of: applying the electric field to the liquid crystal through the switching elements and the pixel electrodes for a time shorter than a response time of the liquid crystal, thereby charging the liquid crystal to excite molecules thereof; scanning the liquid crystal lying at the pixel electrodes corresponding to all the scan lines by applying the electrical field in linear sequential mode, thereby forming one imaging field; forming one frame by combining a plurality of the imaging fields serially; and providing as a result a plurality of tones with a displayed image.
