Patent abstract

A color electrophoretic display with distinct switching areas formed by a segmented top plane electrode opposite driving pixel electrodes. The distinct areas are programmed to switch at different times, thereby reducing the “flashiness” seen by a viewer during an image update. In one embodiment, the color electrophoretic medium of the display includes a reflective white particle and three other sets of particles, each comprising a different subtractive color.
