Color Electrophoretic Image Display Based on Movement of Particles Using Two Driving Electrodes
Abstract:We have proposed novel Color Electrophoretic Image Display, CEPID, based on the movement of white, black and color particles in an insulating liquid. There are non-electrophoretic white particles, negatively charged black particles and positively charged color particles in the cell. The movement of charged particles is controlled by the change of polarity of voltage applied to three electrodes. This CEPID cell displays black/white and color by changing polarity of voltage applied to driving electrodes. Both of black and color particles move to the driving electrodes when each driving electrode is applied to positive and negative voltage, we can see white image through the common electrode.

For more than 30 years, IS&T's series of digital printing conferences have been the leading forum for discussion of advances and new directions in 2D and 3D printing technologies. A comprehensive, industry-wide conference that brings together industry and academia, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems?particularly those involved with additive manufacturing and fabrication?including bio-printing, printed electronics, page-wide, drop-on-demand, desktop and continuous ink jet, toner-based systems, and production digital printing, as well as the engineering capability, optimization, and science involved in these fields. In 2016, the conference changed its name formally to Printing for Fabrication to better reflect the content of the meeting and the evolving technology of printing.
