Abstract
ABSTRACT Time-limited exposure of electrode-free optically rewritable electronic paper is essential for applications, but performance characteristics can be modest. In this study we investigate whether image writer mode can improve kinetics of the photosensitive layer order parameter, which is described by the rotational diffusion model. The model that we developed allows adjusting the transmittance spectra of polarisers. We have found that fairly uniform transmittance spectra of polarisers enable to obtain competitive contrast ratio of 8:1 within 10 s of exposure. In comparison with the long-time exposure, the reflectance coefficient reduces by 24%. Computer-simulated image is consistent with the experimental observations.
