Abstract
A multi-focal plane see-through near-eye display using a transparent projection display is demonstrated. The key component of the transparent projection display is a passive polymer-dispersed liquid crystal (PDLC), which is highly transparent for a large range of incident angles in air but strongly scattering at large oblique angles in high refractive index medium (e.g. glass). The use of a passive device can avoid temporal multiplexing. Such a display is highly transparent in air and can easily deliver full-color images. The proposed method is an important step toward transparent display-enabled multi-focal plane displays.
