| 摘要 |
The present invention relates to a display element drive method performing write at a low speed for still image display and in particular, to a method for driving a display element using cholesteric liquid crystal (electronic paper). The display element includes a plurality of scan electrodes and data electrodes intersecting one another in the opposed state. The drive method executes an empty scan for the scan electrodes before performing an image write process. The scan electrodes are selected in a predetermined sequence and an image write process is performed. According to the drive method, it is possible to suppress a large inrush current generated immediately after the image write. Moreover, it is possible to use a cheap general-purpose driver, apply the method to a cell-less display device, and achieve power saving and a stable display quality.
