1. Field of the Invention
The present invention relates to a method of displaying an image and an electrophoretic display (“EPD”) device for performing the method. More particularly, the present invention relates to a method of displaying images on an EPD panel capable of improving a display quality and an EPD device for performing the method.
2. Description of the Related Art
Generally, an electrophoretic display (“EPD”) device includes two opposing electrodes and a plurality of microcapsules. The microcapsules include a plurality of white ink particles that is negatively charged and a plurality of black ink particles that is positively charged. Only when an electric field is applied to the two electrodes, the white ink particles move in view direction to display white images and the black particles move in view direction to display black images. Lights applied from an external side are reflected by the white ink particles that move the view direction, so that images are displayed. That is, the white and black particles have a bi-stable characteristic. Since each microcapsule is stable in either of a black or a white state, each microcapsule maintains the black or white state without maintaining a voltage across the electrodes. Accordingly, power consumption for the EPD device is reduced.
When a plurality of charges corresponding to a direct current (“DC”) voltage is charged to the particles having the bi-stable characteristics, a lifetime of the EPD device is decreased. In order to prevent the EPD device from decreasing its lifetime and a residual image, a method of compensating the particles moved by data, that is displayed in a previous frame before current data is displayed, has been developed. That is, in the EPD device for displaying an image, a driving interval includes a compensation interval, a display interval and a holding interval.
