Characterization of Electric Charge Density using Electrophoretic Mobility for Studying Electrophoretic and Twisting Ball Displays-Preparation and Characterization of Bichromal Particles for Twisting Ball Display-
The key technology of these two systems is the difference in electric charge density of the display elements since this forms the force driving display element migration/rotation. Therefore, quantification of electric charge density is considered to be essential for controlling these systems. We define electrophoretic mobility as the parameter of electric charge density and study how the electric charge density influences the motion of the display elements using this parameter.
We will also report a new method for preparing balls in twisting ball displays.

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.
