Development of Flexible Electronic Paper with Transparent Polymer Electrodes Prepared through Directly Printing Approach

摘要

A 4.0 in. diagonal and 88 dpi flexible electronic paper with line-shaped electrodes composed of transparent conductive polymer of poly(3,4-ethylene dioxythiophene) and poly(styrenesulfonate) (PEDOT/PSS) was prepared and passive matrix images were successfully displayed. The line-shaped electrodes of the conductive polymer were directly formed onto the flexible polyethylene terephthalate (PET) substrate by using screen printing method. Increase of the viscosity of PEDOT/PSS aqueous suspension and improvement of a screen mask enabled to pattern the line-shaped electrodes in higher resolution.
