Development of Electrofluidic Display Technology (Image 1)

Pixel structure in Electrofluidic Display Technology (EFD)

The pixel structure in Electrofluidic Display Technology (EFD), developed at the University of Cincinnati (UC), that is able to reveal or hide pigments with high contrast and video speed. The reservoir (center circle) holds the pigment until it is ready to be displayed by application of voltage. This is the first technology to electrically switch the appearance of pigments in a manner that provides visual brilliance equal to conventional printed media.

This step toward full-color electronic paper can potentially provide better than 85 percent "white-state reflectance," a performance level required for consumers to accept reflective display applications such as e-books, cell-phones and signage.

Development of the technology was an international collaborative effort involving UC, Sun Chemical, Polymer Vision and Gamma Dynamics.

The research was supported in part by a Faculty Early Career Development (CAREER) award from the National Science Foundation (ECCS 06-40964).
