NEC's 3D display for cell phones

NEC has created a prototype of a 3D display for cellphones that has a resolution of 320x480 pixels. Special glasses are not necessary to see in 3D. NEC is using a lenticular lens to separate the "left" and "right" pixels. I've seen this kind of technology applied on 30"-42" LCD screen. I gave me a headache I won't forget. I guess this was mostly caused by the poor screen resolution. NEC is not productizing this screen yet.
