Abstract

In this paper, the authors propose a novel method to construct a wide viewing two-dimension/three-dimension convertible system with two parallel display devices. With changing the role of each display device, it is possible to convert the display mode between 2D and 3D electrically without any mechanical movement. In 2D display mode, the rear display is used as a white light source and the front display device displays the 2D images. In 3D display mode, the rear display device and the lens array construct 3D images, while the front display device displays electrical masks to enhance the viewing angle of the 3D images. Since the basic principle for 2D and 3D display modes are the same as that of LCD display and integral imaging respectively, other improved techniques for both display modes, which will be accomplished with the progress in researches, can be easily applied to the system. The proposed method is also demonstrated by some experimental results.
