Reflective polarization volume gratings (PVGs) can be used as input and output couplers in a diffractive waveguide‐based augmented reality (AR). To improve the stability and wearing comfort, a thin and lightweight full‐color waveguide display is needed. In this paper, we propose a single full‐color...
