"Digital Paper" was recently proposed as a new medium that offers the advantages of both softcopy and hardcopy. This study examines the possibility of surface electric charge driving a liquid crystal medium using an ion projection head for realizing Digital Paper. A guest-host type polymer dispersed liquid crystal sheet medium was prepared. The optical density of the sheet is almost linear to the surface potential from 160 v to 320 v. The surface electric potential necessary for saturated image formation lies in the range 310 v to 350 v for the media used in this experiment.
