Stereo Viewing Zones Analysis in DLP-based Autostereoscopic Display

To obtain low-cost,super-large-panel autostereoscopic display,and the scheme of 3D monitor based on Digital Light Projection(DLP) was adopted.By simulating the light path of lenticular lens,the characteristics of stereo viewing zones were analyzed.According to the structure and principle of the display,the light distribution figure of stereo viewing zones was calculated.Viewers who stay at the optimal viewing distance can see good stereo images without crosstalk.The setting method of the optimal viewing distance and pixel matching was studied,and the range for the better stereo images was provided.The study on the stereo viewing zones is useful for the design of such autostereoscopic display devices and achieves 150-inch-large panel stereo display with good telepresence and three-dimensional effect.
