Paper Abstract

Recently, the 3D display of the double observation point based on the parallax barrier has attracted attention because of its dual-view points and 2D/3D display compatibility, especially for display applications for mobile screens. At present, onedimensional integral imaging 3D display based on parallax barrier still has some challenges, such as lower resolution and small viewing angles. In order to increase resolution and the viewing angle, in this paper we analyzes the effect of the parallax barrier and parallax aperture width on the 3D image display under the assumption that the parallax barrier pitch is constant. Firstly, according to the geometric optics, the calculation formula of the resolution and the relationship between the viewing angle of the single slit and the aperture width of the slit are derived, further derive the formula for calculating the viewing angle. We had made a one-dimensional integral imaging dual-view 3D display prototype and studied the viewing angle and crosstalk of 3D images under different parallax aperture parameters. Applying the ideal optimal aperture value that we calculated to the prototype, we can finally see the 3D images of the two virtual scenes without crosstalk in the left 5° to 25°and the right 5° to 25°. The experiment results showed that the resolution and the viewing angle of the one-dimensional integral imaging dual-view 3D display increase with the decrease of the aperture width of the parallax barrier.
