Electronic Paper Technology QR-LPD^TM

Abstract

A novel electronic paper technology;Quick Response-Liquid Powder Display (QR-LPD) has been developed. This panel is operated by a new material which behaves just like liquid despite powder form. This electronic paper has the advantages of outstanding image stability, easy viewing, low-power consumption and a high-response time. We have successfully developed thin and light weight flexible electronic paper using QR-LPD technology. Furthermore, we have proved there is the great potential to utilize printable technology for an electronic paper. Direct formation of line-shaped electrodes consisting of transparent conductive polymer of poly (3, 4-ethylene dioxythiophene) and poly (styrenesulfonate)(PEDOT/PSS) was successfully achieved onto a flexible polyethylene terephthalate (PET) substrate by using screen printing method.
