Abstract: A head-mounted device may have a display that displays computer-generated content for a user. The head-mounted device may have an optical system that directs the computer-generated image towards eye boxes for viewing by a user. The optical system may be a see-through optical system that allows the user to view a real-world object through the optical system while receiving the computer-generated image or the optical system may include a non-removable lens and a removable vision correction lens through which an opaque display is viewable. The optical system may include a removable lens. The removable lens may serve as a custom vision correction lens to correct for a user's vision defects. The optical system may have a projection bias lens that places computer-generated content at one or more desired virtual image distances and a corresponding compensation bias lens.

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: A lens module may include a transparent lens element, a lens shaping structure that is coupled to the transparent lens element, and a plurality of actuators that are configured to adjust a position of the lens shaping structure to adjust the transparent lens element. The lens shaping structure may include a plurality of extensions that are each coupled to a respective actuator. To ensure the lens shaping structure has desired curvature between the extensions, the lens shaping structure may have a portion in one or more segments between adjacent extensions that has a property with a different magnitude than an additional portion of the lens shaping structure. The portion between the adjacent extensions may have an increased or decreased rigidity relative to the additional portions. The portion between the adjacent extensions may have a different width, thickness, or Young's modulus compared to the additional portions.

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 lens module with a tunable lens. The tunable lens may be operable in multiple modes such as a normal mode, a presbyopia-mitigation mode, a near-focus mode, and a negative power boost mode. During operation, the electronic device may gather data and adjust the tunable lens based on the gathered data. The tunable lens may be switched from the normal mode to the presbyopia-mitigation mode in response to determining that a nearby object is being viewed through the lens module. The tunable lens may be switched from the normal mode to the negative power boost mode in response to ambient light levels being low and/or eye fatigue levels being high. The tunable lens may switch between modes over a transition period. An output device may notify the user when the tunable lens changes modes.

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: An electronic device may have a display that provides image light to a waveguide. First and second liquid crystal lenses may be mounted to opposing surfaces of the waveguide. An coupler may couple the image light out of the waveguide through the first lens. The second lens may convey world light to the first lens. Control circuitry may control the first lens to apply a first optical power to the image light and the world light and may control the second lens to apply a second optical power to the world light that cancels out the first optical power. Each lens may include two layers of liquid crystal molecules having antiparallel pretilt angles. The pretilt angles and rubbing directions of the first lens may be antiparallel to corresponding pretilt angles and rubbing directions of the second lens about the waveguide.
