<p>The present invention relates to an electro-osmotic dis- play comprising a transparent common electrode arranged on a first transparent substrate, and a pixel electrode arranged on a second substrate. The common electrode comprises a base and at least two fingers extending from that base and the pixel electrode comprises a base and at least one finger extending from that base. The fingers of the common electrode and the pixel electrode are arranged in an interdigitated manner. According to the invention, the fingers of the pixel electrode and the common electrode taper outwardly in a direction away from the base of that electrode. It is stipulated that the use of tapering improves the secondary electro-osmotic flow al- lowing charged pigment particles to be transported away more efficiently.</p> |
