Abstract: A display engine assembly comprises a first imager and a second imager to generate a left image and a right image, respectively, in a head-mounted display device. The left and right images are left and right components, respectively, of a single stereoscopic image. The display engine further comprises an optical waveguide optically coupled to the first imager and the second imager. The optical waveguide is part of a first optical path to convey the left image to a left eye of a user of the head-mounted display device and is also part of a second optical path to convey the right image to a right eye of the user of the head-mounted display device.

Abstract: Introduced here is a display device that comprises a light emitter and a diffractive optical element (DOE) that is optically coupled to receive light from the light emitter and to convey the light along an optical path. The DOE may have an input surface and an output surface parallel to the input surface, where the input surface and the output surface each have a central region and a peripheral region. The DOE further may have optical characteristics such that light exiting the DOE in the peripheral region of the output surface has greater brightness than light exiting the DOE in the central region of the output surface.
