Embodiment Construction

[0020] The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which embodiments of the invention are shown. However, this invention may be embodied in many different ways and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. In the drawings, the size and relative sizes of layers and regions may be exaggerated for clarity.

[0021] It will be understood that when an element or layer is referred to as being "on," "connected to," or "coupled to" another element or layer, it can be directly on, connected to, or may be coupled to another element or layer, or intervening elements or layers may also be present. In contrast, when an element is referred to as being "directly on," "directly connected to," or "directly coupled to" anoth...

Abstract

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.

Description

technical field [0001] 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 an image on an EPD panel capable of improving display quality and an EPD device performing the method. Background technique [0002] Generally, an electrophoretic display ("EPD") device includes two opposing electrodes and a plurality of microcapsules. The microcapsules include a plurality of negatively charged white ink particles and a plurality of positively charged black ink particles. Only when an electric field is applied to these two electrodes, the white ink particles move in the viewing direction to display a white image, and the black ink particles move in the viewing direction to display a black image. Light applied from the outside is reflected by the white ink particles moving in the viewing direction, thereby displaying an image...
