Electrophoretic display and method of making the same

摘要

A configuration for an electrophoretic display device is described that is effective in substantially preventing agglomeration of pigment particles. A suspension medium (in 30) is contained between first (23) and second (25) electrodes to define an electrophoretic display cell; a plurality of pigment particles are dispersed in the suspension medium and a plurality of mechanical members (24) project therein. The members advantageously are sized sufficiently small such that a plurality of members can exist within a minimally visible region of the cell. The mechanical members may be fabricated separately from the remaining parts of the display, allowing for flexibility in the fabrication materials and processing conditions. <IMAGE>
