A display system that simultaneously displays two-dimensional (2D) and three-dimensional (3D) images using a pinhole array on a liquid crystal (LC) panel is proposed. Using the transparent structure of the LC panel, the system can generate or eliminate pinholes electrically and can display a 3D image in a selectable specific area of the display panel, while 2D images are displayed on the rest of the screen. An analysis showing the advantages and limitations of the proposed system is provided. Finally, the proposed principle is proven by experimental results.
[Show abstract][Hide abstract] ABSTRACT: Integral imaging is one of the most feasible directional displays that give different perspectives according to viewing directions.
It has inborn characteristics such as viewing angle, resolution, and depth range because of lens array or pinhole array. In
this paper, recent integral imaging techniques for improving these features in display are reviewed. New approaches such as
integral floating display and two-dimensional three-dimensional (2D/3D) convertible integral imaging method are described
