Abstract

A multilayer display is an autostereoscopic display constructed by stacking multiple layers of LC (liquid crystal) panels on top of a light source. It is capable of delivering smooth, continuous, and position-dependent images to viewers within a prescribed viewing zone. However, the images thus delivered may contain artifacts, which are inconsistent with real 3D scenes. For example, objects occluding one another may fuse together, or get obscured in the delivered images. To reduce such artifacts, it is often necessary to narrow the viewing zone. Using a directional rather than a uniform light source is one way to mitigate this problem. In this work, we present another solution to the problem. We propose an integrated architecture of multilayer and lenticular displays, where multiple LC panels are sandwiched between pairs of lenticular sheets. By associating a pair of lenticular sheets with a LC panel, each pixel in the panel is transformed into a view-dependent pixel, which is visible only from a particular viewing direction. Since all pixels in the integrated architecture are view-dependent, the display is partitioned into several sub-displays, each of which corresponds to a narrow viewing zone. The partitioning of display will reduce the possibility that the artifacts are noticeable in the delivered images. We will show several simulation results confirming that the proposed extension of multilayer display can deliver more plausible images than conventional multilayer display.
