Abstract: To obtain a low cost super large panel auto-stereoscopic display system, 3D monitor based on DLP was proposed. Optical transmission property of lenticular lens was analyzed. By simulating light path of lens, the figure of stereo viewing zones was obtained. With the crosstalk of stereo viewing zones, the parameters of lenticular lens suitable for large panel auto-stereoscopic display were deduced. For the best observing distance, the relationship between virtual cameras' distance and the scene limit positions was analyzed. An about 150-inch-large panel stereo display wall with enhanced three-dimensional effect and telepresence of the monitor at the same time was made.

Key words: viewpoint, stereo viewing zones, crosstalk, best observing distance, virtual cameras' distance, DLP, viewpoint, stereo viewing zones, crosstalk, best observing distance, virtual cameras' distance
