Integral Photography Using Color Electronic Paper

摘要

A new 3D display using color electronic paper is presented. The system consists of a FLEPia, which is a commercially available color e-paper mobile terminal made by Fujitsu Frontech Ltd, and a commercially available hexagonal fly's eye lens. Not only horizontal but also vertical parallax is obtained because the extended fractional view method, which is a kind of integral photography, is adopted. Since the color cholesteric liquid crystal display of FLEPia is essentially reflective, it can display a clear image without backlight, and it does not consume the electric power except when the image is updated. Moreover, it is suitable for integral photography because an unsightly moire is hard to occur; there are no color subpixels that might be interfered with the fly's eye lens. Experiments revealed that a good full color image with the sense of depth was observed under appropriate lighting conditions.
