The amount of information for 3D display is much bigger than that for 2D display. Therefore, many researches about 3D display have used multiplexing of conventional display devices sequentially or spatially. We propose a new 3D display system using a concave cylindrical mirror and tracking technology. The concave cylindrical mirror can be used like a convex lens in the polar axis. It means that the concave cylindrical mirror can float an image from a 2D display panel and give directional images to a viewer in the optical axis. To give the parallax to the viewer, the tracking technology will be used to generate the images according to the position of the viewer. We design a structure with a cylindrical reflective film and a 2D display panel. And, we use the tracking technology to provide parallax which cannot be made in the cylindrical reflective film. Further explanations of the proposed structure and experimental results will be presented.
