Improvement of Image Contrast in Toner Display
Abstract:Image contrast in toner display based on an electrical movement of black and white charged particles has been improved. Two types of black and white particles charged different electric polarity are enclosed between a two transparent electrodes. The black and white solid images are displayed by the switch of polarity of applied voltage in toner display cell. The image contrast ratio of reflectance of white to black solid image has been increased when the new type of white and black toner particles are used in toner display cell.

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.
