Abstract

A black-matrix-type electroosmotic display (EOD) device is described. It makes use of a transparent porous substance with fine dot-shaped depressions on its surface and whose pores are filled with a transparent liquid with a high electroosmotic mobility. The device is manufactured using an embossing process and conventional printing techniques. The principle of operation involves electroosmotic movement to control the wetting of the depression´s sloped surfaces on the porous substance. Characteristics of the EOD device are presented and a multicolor experimental numerical display is described. The EOD device has a relatively fast response time and low power consumption (less than 10² μW/cm²)
