多层显示器是通过在光源的顶部上堆叠多层LC（液晶）面板而构造的自动立体显示器。它能够在规定的观看区域内向观看者提供平滑、连续和位置相关的图像。然而，这样传送的图像可能包含与真实的3D场景不一致的伪影。例如，彼此遮挡的对象可能融合在一起，或者在所传递的图像中变得模糊。为了减少这样的伪影，通常需要使观看区域变窄。使用定向光源而不是均匀光源是缓解此问题的一种方法。在这项工作中，我们提出了另一种解决方案的问题。我们提出了一个集成架构的多层和透镜状显示器，其中多个LC面板夹在透镜状片对之间。通过将一对透镜片与LC面板相关联，面板中的每个像素被转换成仅从特定观看方向可见的视图相关像素。由于集成架构中的所有像素都是视图相关的，因此显示器被划分为若干子显示器，每个子显示器对应于窄的观看区域。显示的分区将降低在所传送的图像中伪影是明显的可能性。我们将展示几个模拟结果，证实多层显示器的拟议扩展可以提供比传统多层显示器更合理的图像。
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.
