Three-dimensional display with optimized view distribution

Abstract. A three-dimensional (3-D) display with optimized view distribution is proposed. The proposed 3-D display consists of a two-dimensional (2-D) display panel, a pixel mask, and a lenticular lens. The 2-D display panel is used to provide parallax images. The pixel mask has a designed pinhole array and is located close to the 2-D display panel. This pinhole array can modulate the location and size of the pixels on the 2-D display panel to provide an optimized view distribution. Finally, the lenticular lens projects the pixels in different spatial directions to form 3-D images. Different from conventional 3-D displays, the proposed 3-D display can concentrate views into the center area and form a better parallax continuity. A prototype of the proposed 3-D display is developed. Experiment results agree well with the theory.
