Abstract
The present invention relates to an improved EPD which comprises the in plane switching mode. More specifically, the EPD of the present invention comprises isolated cells formed from microcups of well defined size, shape and aspect ratio and the movement of the particles in the cells is controlled by the in-plane switching mode. The EPD of the present invention may be produced in a continuous manufacturing process, and the display gives improved color saturation.
