Abstract: An augmented reality (AR) display device includes a display engine configured to project light of an image, and a waveguide configured to receive and output the projected light. The display engine includes a light source unit, a reflective display panel, and a projection optical system. The projection optical system includes an iris and a projection lens group arranged between the iris and the reflective display panel. The light source unit includes a light source or a light exit end positioned near the iris in a position deviating from an optical axis of the projection optical system, such that an incident angle range of light incident to the display panel does not overlap with a reflection angle range of light reflected from the display panel. The iris includes an effective opening through which light reflected from the display panel passes.

Abstract: The disclosure relates to augmented reality devices, and more particularly, to augmented reality glasses and methods for operating the same. An augmented reality display device is provided. The augmented reality display device includes a projection system, an optical compensator positioned after the projection system, and a flexible waveguide. The flexible waveguide can change its curvature and comprises an input diffraction grating and an output diffraction grating. The optical compensator is configured to introduce pre-distortion to the image and optically zoom the image received from the projection system, the pre-distortion in the image and optical zoom of the image being opposite to those introduced by the flexible waveguide to the undistorted image in accordance with chosen radius of the flexible waveguide. Flexible diffraction grating distorts the pre-distorted image. The output diffraction grating outputs undistorted image to a user's eyes.
