Abstract
To realize a practical 3-D display system, we consider that it is necessary to combine a construction of 3-D image on a space and method utilizing 3-D visual illusion. In this paper, as examples of individual technologies, we present 3-D display using a varifocal lens and DFD (Depth-fused 3-D) display. In DFD display, we mention a basic phenomenon of visual illusion, a protruding 3-D display, a large area display and depth perception when both eyes have a visual acuity difference. In 3-D display using varifocal lens, we explain basic structure, driving method of liquid-crystal lens (key device), simple 3-D images and a new driving method of key device.
