    Abstract: A head-mounted device may have lenses. A user may view images through the lenses from eye boxes. The lenses may be tunable liquid lenses. Each lens may have a lens chamber. The lens chamber of the lens may have rigid and/or flexible walls that form optical lens surfaces. Actuators and/or pump and reservoir systems may deform the lens surfaces in response to control signals from a control circuit to tune the lens. Each liquid lens may have oil or other liquid in the lens chamber for that lens. Inorganic dielectric particles or other refractive-index-adjustment particles may be used to adjust the refractive index of the lens. The particles may be subwavelength in size.

    Abstract: A head-mounted device may include one or more adjustable lens elements. The adjustable lens element may include a transparent substrate, a collapsible wall that forms an enclosed perimeter on the transparent substrate, and a flexible membrane on the collapsible wall that together define an interior volume. The interior volume may be filled with a fluid. The adjustable lens element may include a lens shaping component that applies a force to the collapsible wall to adjust a height of the collapsible wall relative to the transparent substrate, which in turn may be used to adjust the shape of the flexible membrane and thus the lens power of the lens element. The collapsible wall may have bellows that allow the collapsible wall to fold on itself when compressed, thereby minimizing unintended lateral movement of the collapsible wall.

    Abstract: Techniques for implementing and/or operating an electronic device that includes or utilizes a display panel. The display panel includes an organic light-emitting diode layer, an encapsulation layer disposed over the organic light-emitting diode layer, and a color filter layer disposed over the encapsulation layer. The color filter layer overhangs the organic light-emitting diode layer and comprises a first color filter cell of a first color component sub-pixel that at least partially overlaps an organic light-emitting diode of a second color component sub-pixel that is a different color compared to the first color component sub-pixel.

    Abstract: A lens module in a head-mounted device may include a fluid-filled chamber, a semi-rigid lens element that at least partially defines the fluid-filled chamber, and at least one actuator configured to selectively bend the semi-rigid lens element. The semi-rigid lens element may become rigid along a first axis when the lens element is curved along a second axis perpendicular to the first axis. Six actuators that are evenly distributed around the periphery of the semi-rigid lens element may be used to control the curvature of the semi-rigid lens element. The semi-rigid lens element may initially be planar or non-planar. For example, the semi-rigid lens element may initially have a spherically convex surface and a spherically concave surface. A tunable spherical lens may be incorporated into the lens module to offset a parasitic spherical lens power from the semi-rigid lens element.

    Abstract: An electronic device may include a display and a lens module through which the display is viewable. The lens module may include a tunable lens with an adjustable spherical power, cylindrical axis, and/or cylindrical power. To tune the tunable lens to compensate for a viewer's eyesight, the display may present at least one target. The optical power of the tunable lens may be set based on the point of gaze relative to the at least one target. Multiple targets with associated optical powers may be presented and the optical power of the tunable lens may be set depending on which target is aligned with the point of gaze. The display may present an image through a masking layer with a ring of pinhole pairs. The electronic device may include an input device that receives user input regarding a perceived image associated with the display and the masking layer.

    Abstract: An electronic device may include an optical module with a display and a tunable lens. During operation, the electronic device may gather data and adjust the tunable lens based on the gathered data. The optical module may include a non-adjustable lens element with convex curvature in addition to the tunable lens. The optical module may include a Fresnel lens element in addition to the tunable lens. The optical module may include a catadioptric lens in addition to the tunable lens. The optical module may include a catadioptric lens that includes the tunable lens. The optical module may have a birdbath architecture that includes the tunable lens. The optical module may include a waveguide and the tunable lens may be an adjustable positive bias lens and/or an adjustable negative bias lens.
