The viewing zones in the conventional dual-viewing-zone three-dimensional (3D) display are still narrow. We propose a dual-viewing-zone 3D display that consists of a display panel, a parallax barrier, and a barrier array. The adjacent slits are separated by the barrier. Two adjacent elemental images that are respectively obtained from two 3D scenes are located between two adjacent slits. The light rays from two adjacent elemental images that are alternatively arranged in the horizontal direction are only integrated by a slit. The light rays from the left elemental images are propagated into the left viewing zone, whereas those from the right elemental images are propagated into the right one. Different 3D images are reconstructed in the left and right viewing zones. The experimental results prove that two viewing zones are both enlarged in the proposed dual-viewing-zone 3D display.

.Low optical efficiency is a drawback of a dual-view integral imaging display based on a pinhole array. Therefore, we propose a high optical-efficiency dual-view integral imaging display. It is composed of a display panel and a non-uniform pinhole array. The left-view and right-view sub-elemental images are alternatively aligned in horizontal direction. The horizontal aperture widths of the pinholes are identical. The horizontal light rays from the left-view and right-view sub-elemental images are modulated into different directions. The vertical aperture widths of the pinholes are enlarged from upper and lower edges to center. Therefore, the vertical light rays from the sub-elemental images are not parallel. The vertical viewing angle is related to the vertical aperture width of the first row pinhole, whereas the optical efficiency is related to the vertical aperture widths of all pinholes. The optical efficiency is improved by optimizing the vertical aperture widths of the pinholes. A prototype is developed, and the experimental results prove the hypothesis.

Low aperture ratio is a problem in the conventional dual-view integral imaging (DVII) display using a point light source array. A high-aperture-ratio DVII display using a gradient width point light source array is reported in this work. The elemental Images 1 and 2, which are alternatively aligned on a liquid crystal panel, are illuminated by the light rays emitted from an assigned point light source. The optical path is optimized by optimizing the widths of the point light sources. The aperture ratio of the proposed DVII display was demonstrated as 1.88 times the conventional DVII display. Experiments showed that the vertical viewing range is related to the vertical width of the first row point light source, whereas the aperture ratio is related to the vertical widths of all point light sources. By optimizing the widths of the point light sources, the aperture ratio is enhanced without loss of viewing range.
