ABSTRACT 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.

    ABSTRACT: We propose a two-dimensional (2D) and three-dimensional (3D) convertible bi-sided integral imaging. The proposed system uses the polarization state of projected light for switching its operation mode between 2D and 3D modes. By using an optical module composed of two scattering polarizers and one linear polarizer, the proposed integral imaging system simultaneously provides 3D images with 2D background images for observers who are located in the front and the rear sides of the system. The occlusion effect between 2D images and 3D images is realized by using a compensation mask for 2D images and the elemental images. The principle of proposed system is experimentally verified.

    ABSTRACT: A two-dimensional (2D) / three-dimensional (3D) convertible display system based on integral imaging is proposed to adopt a novel switchable point light source array, which is implemented using the polarization modulator and the polarization selective scattering film that transmits or scatters the incident light due to its polarization direction. The 2D and the 3D display modes of the proposed system can be modulated by controlling the polarization direction of back light using the polarization modulator. We explain the basic principles of the proposed system and verify the feasibility of the system through preliminary experiments.

    ABSTRACT: A method to uniformize the brightness of elemental image for the frontal projection-type three-dimensional (3D) display is proposed. A frontal projection three-dimensional display which is possible to realize glasses-free 3D display by combining a polarizing screen with a front projector has been proposed recently. This method uses a quarter-wave retarding film (QWRF) and a polarizer with slits, and makes the audience see different directional views. This structure can change the polarization state orthogonally, so the image from projector is partially blocked when the image is reflected and meets the films. However, in this method, the quality of the reconstructed 3D image could be degraded since the light intensity at the barrier-free regions of parallax barrier polarizer is brighter than that at the parallax barrier polarizer. We proposed two methods to relieve this difference, a parallax barrier rearrangement method and gray level compensation of illumination. By adopting two methods, we anticipate that the quality of reconstructed 3D image can be enhanced because of brightness uniformity in directional-view images in the frontal projection-type 3D display method.
