PCb05 イオン流照射によるG-H型液晶表示を用いたデジタルペーパーの検討

抄録

Surface electric charge driving of LC medium was tested using an ion projection head. We used Guest-Host type liquid crystal medium which has dichroic dye in Smectic-ALC droplets. White images on gray background were obtained with contrast ratio of 1.83. Reflection characteristics of this medium were measured and ideal characteristic idependent to reflection angle was obtained. It was confirmed that clear image formation and erasing are repeatedly possible on this medium by using an ion projection head and that this medium has ideal characteristics of viewing angle. Guest-Host type liquid crystal medium with ion projection head is thus considered to be promising as a Digital Paper technology.
