Effects of Triboelectrical Charge of Toners on Display Characteristics of Toner Display
Abstract:Toner Display is based on an electrical movement of charged toner particles. Two types of black and white particle charged in the different electric polarity are enclosed in the air space between two transparent electrodes. The black toners are collected to the electrode by an electrostatic force across the insulting layer to display a black image. Those toners can be put to the counter electrode by applying a reverse electric field, and white solid image is displayed.
The display contrast and driving voltage depend on the electrical charge of toner particle in the display cell. In this study, the triboelectric charges of particles in the display cell were measured using Q/M meter. Those charges depend on the mixture ratio of two toners. The triboelectric charging mechanism between small toner particles was discussed.

For more than 25 years, NIP has been the leading forum for discussion of advances and new directions in non-impact and digital printing technologies. A comprehensive, industry-wide conference, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems, including drop-on-demand ink jet, wide format ink jet, desktop and continuous ink jet, toner-based electrophotographic printers, production digital printing systems, and thermal printing systems, as well as the engineering capability, optimization, and science involved in these fields.
Since 2005, NIP has been held in conjunction with the Digital Fabrication Conference.
