Directional Display for Three-Dimensional Image Generation

Abstract

We have developed high-density directional (HDD) displays which provides a natural three-dimensional image. The accommodation-vergence conflict does not occur and very smooth motion parallax is obtained. A large number of directional images are displayed simultaneously in the different horizontal directions with a very small angle pitch. There are two different display systems for the HDD display: one is the projection type system and the other is the flat-panel type system. We have constructed 64-, 72-, and 128-directional displays. Three applications of the HDD display are shown: the medical application, the high-appearance image generation, and the mobile application.
