The eye illuminator includes a light-emitting diode, a flexible circuit to which the light-emitting diode is coupled, and a stiffener laminated to the flexible circuit with one or fewer layers of adhesive. The lens is removably coupled to the display indirectly by the stiffener.

Abstract: A wearable device may include a head-mounted display (HMD) for rendering a three-dimensional (3D) virtual object which appears to be located in an ambient environment of a user of the display. The relative positions of the HMD and one or more eyes of the user may not be in desired positions to receive, or register, image information outputted by the HMD. For example, the HMD-to-eye alignment may vary for different users and change over time (e.g., as a given user moves around or as the HMD slips or otherwise becomes displaced). The wearable device may determine a relative position or alignment between the HMD and the user's eyes. Based on the relative positions, the wearable device may determine if it is properly fitted to the user, may provide feedback on the quality of the fit to the user, and may take actions to reduce or minimize effects of any misalignment.

Abstract: A spatial direction of a wearable device that represents an actual viewing direction of the wearable device is determined. The spatial direction of the wearable device is used to select, from a multi-view image comprising single-view images, a set of single-view images. A display image is caused to be rendered on a device display of the wearable device. The display image represents a single-view image as viewed from the actual viewing direction of the wearable device. The display image is constructed based on the spatial direction of the wearable device and the set of single-view images.

Abstract: An electronic device may include a display module that produces light having an image, a lens that directs the light to a waveguide, and a waveguide that directs the light to an eye box. The lens may produce a foveated image in the light by applying a non-uniform magnification to the image in the light. The non-uniform magnification may vary as a function of angle within a field of view of the lens. This may allow the foveated image to have higher resolution within the central region than in the peripheral region. Performing foveation using the lens maximizes the resolution of images at the eye box without increasing the size of the display module. Control circuitry on the device may apply a pre-distortion to the image that is an inverse of distortion introduced by the lens in producing the foveated image.

Abstract: To reduce the amount of space occupied in the inactive area of a display by gate driver circuitry, at least a portion of the gate driver circuitry may be positioned in the active area of the display. To accommodate the gate driver circuitry, emissive sub-pixels may be laterally shifted relative to corresponding thin-film transistor sub-pixels. This allows for the thin-film transistor sub-pixels to be grouped adjacent to the central area of the active area, leaving room along an edge of the active area to accommodate one or more additional display components such as gate driver circuitry or fanout portions of data lines.

Abstract: A head-mounted device may have a head-mounted housing. The head-mounted housing may have rear-facing displays that display images for a user. The images are viewable from eye boxes while the head-mounted device is being worn by the user. The displays may be mounted in left and right optical modules that have respective left and right lenses. A positioning system may be used to adjust the spacing between the left and right optical modules to accommodate different interpupillary distances. An adjustable heat extraction system may be provided that includes fans configured to force air between airflow inlets and outlets past heat sinks. The heat sinks may have fins that are adjusted in orientation and/or that are otherwise adjusted based on changes in optical module spacing. The airflow inlets and/or outlets may have adjustable louvers or other movable members that allow these ports to be fully opened, fully closed, or partly closed.

Abstract: An electronic device may include a display module that produces foveated images having high and low resolution regions. The module may include a reflective display panel that produces first reflected light during first time periods and second reflected light during second time periods. The first reflected light may reflect off of a beam splitter to form the low resolution region of the foveated image. The second reflected light may be transmitted by the beam splitter, de-magnified by a lens, and redirected by an optical steering element to produce the high resolution region at a desired, adjustable, location in the foveated image. The reflective display panel may be replaced by sets of emissive display panels that concurrently display the high and low resolution regions in the foveated image. The sets of emissive display panels may be replaced by front-lit reflective display panels.
