“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 liquid crystal sheet medium was prepared. An ion projection head with charge dot density of 300 dpi was used for surface charge formation.

It was confirmed that white images could be repeatedly formed on a black background by ion projection followed by image erasure to the black background by heating. It is demonstrated that this sheet medium has ideal characteristics; it reproduces the viewing angle and flexibility of paper. This method is thus promising as a candidate for realizing Digital Paper.
