Abstract

We analyze the light efficiency of a virtual reality (VR) system from display panel to eyebox, and brightness non uniformity caused by the imaging process of the VR lens. Two types of light engines: OLED and LCD are evaluated. For an OLED panel, we optimize the microcavity structure to suppress the image non-uniformity, while keeping a high optical efficiency. For LCD, we propose a 2D patterned prism film to locally modulate the radiation pattern for optimizing the light collection efficiency while minimizing the vignetting effect. The proposed optimization method provides valuable guidelines for designing next-generation display devices for VR headsets.
