Abstract
An electrophoretic display able to operate on a reduced power supply includes a display panel and a driving circuit electrically connected to the display panel. The display panel includes a plurality of first electrophoretic particles and a plurality of second electrophoretic particles. The driving circuit is configured to provide a balance signal to the display panel during a balance period, provide a mixed signal to the display panel during a mixing period, and provide a driving signal to the display panel during a coloring period. The balance period, the mixing period, and the coloring period are sequential in time, and a preset time interval is between each of the periods.
