Paper Display Module Having Backside Electrode
Abstract:This paper presents a paper display module, which is fabricated on a flexible paper substrate by using a printing method. Due to the price competitiveness superior to the existing semi-conducting processes, the printing technology has begun to get into the spotlight as a manufacturing tool in many industrial fields, including printed electronics, flexible displays, PCB circuits, RFID-tag, and so on. The paper display module has 75 segments. The size of each segment is 5.78mm × 4.60mm and the thickness is around 220μm, including paper thickness, 100μm. The substrate is 130gsm paper which is generally applicable to a color laser printer. The printed paper display is more flexible than the radius of curvature, 5mm. For increasing the effective display area ratio, the address and common electrodes are located in the backside of the paper. Thus, the ratio is around 82 %. The fabricating process consists of 6 steps: Via-hole laser drilling; Backside electrode printing; Bottom electrode printing; Dielectric printing; Phosphor printing; Transparent electrode printing. As the electrodes, silver ink was used. The via-holes are automatically filled when the backside electrode and bottom electrode are printed in turn.

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.
