Abstract
Light field displays deliver realistic 3D content by representing scenes through a collection of light rays, offering an immersive and lifelike viewing experience. Among various implementations, spatial-multiplexing light field displays have gained increasing attention for their ability to provide full parallax without requiring micro-displays with high frame rates or complex light modulation. However, light leakage between adjacent subviews leads to stray light and ghost images. Placing a grid-like blocker on the micro-display can separate subviews but requires high manufacturing precision and is best applicable for emissive displays only. In this paper, we consider reflective displays because of their frame rate and brightness advantages and propose a polarization-alternating beam splitter to direct light and address the crosstalk issue for reflective displays. Experimental results show that the proposed approach reduces crosstalk by 95% while preserving the refocusing effect of light field displays.
