Abstract: An augmented reality device includes an eyeglass frame and a combiner mounted on the eyeglass frame. The combiner includes an inner surface and an outer surface disposed opposite the inner surface. The device further includes an active shutter lens mounted on the combiner and an image projector mounted on the eyeglass frame and configured to project display light to the combiner such that a first portion of the display light is emitted from the inner surface of the combiner and a second portion of the display light is emitted from the outer surface of the combiner. The device additionally includes a processor coupled to the image projector and the active shutter lens. The active shutter lens is configured to shield the display light emitted from the outer surface of the combiner. The combiner is configured to emit ambient light from the inner surface thereof.

Abstract: A head-mounted display apparatus-includes a lens frame, a lens, and a display module. Both the lens and the display module are disposed on the lens frame. The lens includes a first part and a second part. The first part is adjacent to the second part. The first part is configured to transmit ambient light. The second part is configured to transmit the ambient light and display light emitted by the display module. A ratio of the transmittance of the second part to the transmittance of the first part is within a threshold range. In one embodiment, the threshold range may be between 0.5 to 1.5.
