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.
