摘要： A method of displaying images on an electrophoretic display (“EPD”) panel includes displaying a (K)-th image on the EPD panel including a plurality of electrophoretic particles, wherein K denotes a natural number. Then, when an interrupt signal for converting images is inputted during one of a plurality of driving intervals, a charge of the electrophoretic particles is compensated, which is charged in correspondence with the (K)-th image displayed on the EPD panel before the interrupt signal is inputted, and then a (K+1)-th image is displayed on the EPD panel. Thus, when the interrupt signal is inputted during one of the driving intervals displaying the (K)-th image data, the charges that are charged in the particles are compensated in correspondence to the (K)-th image data, and then the (K+1)-th image is displayed so that display quality may be enhanced.
