Japan Display Inc, (JDI) showed a number of interesting demos including two 3D displays. One was an aerial floating display that featured the image of a fire that appeared to be floating inside a box. Attendees were invited to touch the fire which evoked some very tentative movements from some. There was a camera to detect when a person placed their hand in the flame and some sort of thermal energy (IR?) that made the person’s hand feel hot when they touched the floating image.
The image did not look very good and it was generated from the company’s 19.5” 3D display that uses their HxDP pixel technology which has the same horizontal resolution in 2D mode as in 3D mode. The demo was developed in cooperation with Utsunomiya University. In session 29, Utsunomiya University working with Mitsubishi described an aerial image prototype, but there was not explanation of how the JDI demo was created.
JDI also showed a light field 17” display based upon an 8K panel. It offered a very high 130-degree viewing angle with horizontal parallax and it is not based upon a micro-lens array architecture. There were few details available other than to note that JDI’s proprietary pixel rendering algorithms were used. The images of the fish looked OK with a height of 3-4 inches and a very small depth of field. That it, the focus appeared to be about ½ inch up from the screen surface with other elements above and below out of focus. – CC
