Abstract

A new approach is presented to enhance the angular resolution of high-density point light source (HPLS) displays. Some of the lights emitted from the edge of point light sources (PLSs) in a conventional HPLS display do not contribute to the creation of three-dimensional (3D) images. As a result, the 3D images formed at the edges of the display have a low angular resolution. Therefore, our proposed display contains four boundary mirrors that are positioned to utilize these lights. We simulated the angular resolution in the proposed system and experimentally demonstrated the feasibility of the new method. By reflecting the light rays in the mirror that are not used to create the 3D images, we have effectively resolved the issue of low angular resolution in 3D images at the edges of the HPLS display.
