Paper Abstract

The advantage of a lenticular type three-dimensional (3D) display is its simple structure consisting of a flat-panel display and a lenticular sheet. The disadvantages are the limited viewing angle and the existence of flipped 3D images. In this study, we propose a technique which uses a curved screen display and a curved lenticular sheet in order to enlarge the horizontal viewing angle. A mask plate is placed in front of the curved screen in order to eliminate flipped images. A lenticular sheet with the lens pitch of 30 lpi was curved with the radius of 300 mm. The image behind the lenticular sheet was printed on a paper with 2,400 dpi using a DDCP printer instead of using a curved screen display. The viewing angle was enlarged to 106°. Rays were emitted into 80 different horizontal directions with the angle pitch of 0.65°. The mask plate completely eliminated flipped 3D images.
