Abstract
For a spatial-multiplexed 3D display, trade-off between resolution and number of view-zones are usually unavoidable due to the limited number of pixels on the screen. In this paper, we present a new autostereoscopic system, named as "integrated-screen system," to substantially increase the total number of pixels on the screen, which in turn increase both the resolution and number of view-zones. In the integrated-screen system, a large number of mini-projectors are arrayed and the images are tiled together without seams in between. For displaying 3D images, the lenticular screen with predesigned tilted angle is used for distributing different viewing zones. In order to achieve good performance, we design a brand-new projector with special lens set to meet the low-distortion requirement because the distortion of the image will induce serious crosstalk between view-zones. The proposed system has two advantages. One is the extensibility of the screen size. The size of the display can be chosen based on the applications we deal with, including the size of the projected pixel and the number of viewing zones. The other advantage is that the integrated-screen system provides projected pixels in great density to solve the major problem of the poor resolution that a lenticular-type 3D display has.
