Realization of electronic 3-D display combining multiview and volumetric solutions

The authors propose an electronic 3D display combining a multiview display and a volumetric display. Conventional multiview displays often give the viewers severe eyestrains because of the contradiction between binocular convergence and focal accommodation of the eyes. Though volumetric displays are free from the contradiction, they cannot express occlusion or gloss of the objects. The proposed system overcomes these disadvantages at once by displaying colors by the multiview display part and fine contrast of edges by the volumetric display part. As for the multiview display we use conventional multiview technologies. As for the volumetric, we use multilayer monochrome TFT liquid crystal panels. Here we can use monochrome panels because the volumetric part is just in charge of expressing edge contrast. This can sufficiently lead proper accommodation since focal accommodation of our eyes is dependent only on the edge of the image. To connect the edges of adjacent panels smoothly, we apply DFD approach, where the point in the middle of two panels is expressed by depiction on both panels.
