Novel display method for electronic paper using electro-rheological fluid

A novel display method using electro-rheological fluid is studied as a candidate technology for Electronic Paper. Electrorheological fluid has the remarkable characteristic that its liquidity can be locally controlled. This fluid form a chain structure in the presence of an electric field. This behavior can be used to form a pixel in a display system when the fluid occupies a cell with control electrodes. In this report, imaging characteristics are evaluated using various control electrode arrangement. The cyclic rewriting behavior confirmed in this study shows the potential of this method as an imaging lechnology for Electronic Paper.
