Samsung has just filed yet another patent application for a holographic 3D projection display cell phone, and while this idea is cool, I’m not sure whether I buy it since there are way too many technical issues involved and to consider.
Although it has been assumed in the above description that the panel-type waveguide according to the present invention is used as a screen, on which source images emitted by the optical unit are two-dimensionally displayed, the panel-type waveguide may be replaced with a three-dimensional hologram screen so that source images emitted by the optical unit are three-dimensionally displayed on a plane spaced from the hologram screen by a predetermined distance.
Will you pick up a handset that features holographic 3D optical displays? I bet they’d cost a bomb and drain a battery faster than a Hummer drinks fuel.
