Abstract

Electrokinetic motion of fullerene ($C_{60}$) particles in liquid crystal (LC) medium under an in-plane electric field has been studied for the application to the electronic paper display. Fullerenes move in the direction of applied electric field due to interaction between the induced dipole moment on $C_{60}$ and external electric field at lower threshold voltages compared to other devices such as QR-LPD (Quick Response Liquid Powder Display) and TBD (Twisting Ball Display). We also confirmed the bistability of fullerene particles in LC medium and the results showed that the 87% and 81% of original reflectance or transmittance of image was retained after 24 hours and 48 hours respectively. Our studies show the possibility that fullerenes can be used for electronic paper display.
