摘要：

A three-dimensional (3D) display with smooth motion parallax and large viewing angle is demonstrated, which is based on a microlens array and a coded two-dimensional (2D) image on a 50 inch liquid crystal device (LCD) panel with the resolution of 3840 x 2160. Combining with accurate depth cues expressing, the flipping images of the traditional integral imaging (II) are eliminated, and smooth motion parallax can be achieved. The image on the LCD panel is coded as an elemental image packed repeatedly, and the depth cue is determined by the repeated period of elemental image. To construct the 3D image with complex depth structure, the varying period of elemental image is required. Here, the detailed principle and coding method are presented. The shape and the texture of a target 3D image are designed by a structure image and an elemental image, respectively. In the experiment, two groups of structure images and their corresponding elemental images are utilized to construct a 3D scene with a football in a green net. The constructed 3D image exhibits obviously enhanced 3D perception and smooth motion parallax. The viewing angle is 60 degrees, which is much larger than that of the traditional II.
