Dual-view one-dimensional integral imaging display using parallax barrier

A dual-view one-dimensional integral imaging display using parallax barrier is proposed. It is composed of a display panel, a parallax barrier, a polarized array, and two pairs of polarized glasses. The polarized array consists of two kinds of orthogonal polarized units that are alternately aligned. Two kinds of elemental images are aligned to the corresponding polarized units, respectively. The lights emitted from two kinds of elemental images are, respectively, modulated by the corresponding slits and polarized units, and two three-dimensional (3D) images are simultaneously reconstructed in the viewing zone. Two pairs of orthogonal polarized glasses are introduced to separate two reconstructed 3D images. Only one of the two reconstructed 3D images is seen by wearing either pairs of polarized glasses. An experimental setup was developed, and the viewing angle of the dual-view one-dimensional integral imaging display is proportional to the aperture width of the slit. The restriction between the viewing angle and the optical efficiency is resolved in the proposed dual-view one-dimensional integral imaging display.
