Abstract

We propose Depth Cube Display (DCD) method using depth map. The structure of the proposed method consists of two parts: A projection part composed of projector for generating image and a Twisted Nematic Liquid Crystal display (TNLCD) as polarization modulating device for adjusting the proper depth and a display part composed of air-spaced stack of selective scattering polarizers which make the incident light to scatter selectively as the polarization of light rays. The image from projector whose depth is determined as passing through the TN-LCD displaying depth map progresses into the stack of selective scattering polarizers and then three-dimensional image is generated. At that time, the polarization of each polarizer is set 0°, 45° and 90° sequentially, and then the incident light rays are scattered by different polarizer as the polarization of these rays. If the light ray has the polarization between those of polarizers, this light ray is scattered by multi polarizers and the image of this ray is generated on gap between polarizers. The proposed method is more simple structure and implemented easily than previous DCD method.
