A device in which one or more reflective collector elements receive image data from one or more light-emitting visual sources to be transmitted to an eyebox, which together form elements of a head mounted display ("HMD") useful for augmented reality ("AR") or virtual reality ("VR") applications, and where the one or more reflective collector elements are cropped to receive a portion of the image data from the one or more light-emitting visual sources, such that the etendue product at the one or more reflective collector elements is about the same as the etendue product within the eyebox.
A hybrid reflective/refractive HMD includes a structural frame, refractive optical lens elements, and optics housings coupled to the structural frame and positioned in front of a user's first and second eyes. Light-emitting visual sources and reflective optical surfaces are contained in the optics housings. Visual content is transmitted from light-emitting visual sources to the reflective optical surfaces. The visual content is reflected within the reflective optical surfaces at least four times without passing through a refractive optical lens element. The visual content is transmitted to the user's first eye or the user's second eye. Simultaneous with the transmission of the visual content to the user's first eye or the user's second eye, a real-world view of the outside surrounding environment is transmitted to the user's first eye or the user's second eye. The visual content is overlaid onto the real-world view of the outside surrounding environment.

Head mounted display having alignment maintained via structural frame
A head mounted display device includes a structural frame arranged generally along a first axis and a second axis for viewing along a third axis, the first, second, and third axes being mutually perpendicular. The structural frame includes opposing upper and lower rims between which are defined left and right openings. Left and right micro-displays are coupled to the structural frame, and are configured to project visual content in a substantially forward direction along the third axis toward the left and right openings, respectively, and away from a user. Left and right optical elements are coupled to the structural frame and respectively positioned over the left and right openings and each include an at least partially reflective surface facing in a substantially rearward direction along the third axis. The structural frame maintains the optical elements in alignment to define an optical light path for reflectively guiding a light ray bundle from the micro-displays to a user's eyes.

A head mounted display device includes a structural frame arranged generally along a X-axis and a Y-axis for viewing along a Z-axis, the X, Y, and Z axes being mutually perpendicular. A micro-display is coupled to the structural frame, and configured to project visual content in a substantially forward direction along the Z-axis away from a user. A group of one or more optical elements with reflective optical surfaces is coupled to the structural frame and respectively positioned on a front side of the micro-display to reflectively guide a light ray bundle from the micro-display to a user's eye. A micro-display alignment mechanism is mounted to the structural frame and configured to align and control the reflectively guided light ray bundle from the micro-display to the user's eye by positioning the micro-display along the X and Z axes.

A method for assembling a head mounted display includes providing a rigid structural frame, and forming an inner optical assembly by assembling optical components to the structural frame including at least one micro-display configured to generate an image, and at least one reflective optical component configured to direct the image to a user's eye. The method includes assembling an outer frame to the inner optical assembly to provide protection for the optical components and customization of the head-mounted display for the user.
