Full-color electroholographic three-dimensional display system employing light emitting diodes in virtual image reconstruction

Abstract

A full-color electroholographic 3-D display system employing LEDs is presented, and a virtual image reconstruction technique for it is studied. It is shown that the image blur observed in the reconstruction is suppressed to a lower level than in reconstruction employing a metal halide lamp. In addition, direct, independent drives on LEDs through RGB waves make the adjustment of white balance easier, and a wide viewing angle can be attained. Full-color, high-contrast 3-D images are obtained.
