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.
展示了一种使用透明投影显示器的多焦平面透视近眼显示器。透明投影显示器的关键组件是无源聚合物分散液晶（PDLC），它在空气中对大范围入射角具有高透明度，但在高折射率介质（如玻璃）中以大倾斜角时会强烈散射。使用无源器件可以避免时间复用。这种显示器在空气中具有高透明度，并且可以轻松传输全彩色图像。所提出的方法是迈向启用透明显示的多焦平面显示器的重要一步。
