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.

Electronic device with a tunable lens

A head-mounted device may include a lens module with a least one adjustable lens. The head-mounted device may be wirelessly paired to an electronic device such as a cellular telephone, watch, laptop computer, etc. To correct for presbyopia, the optical power of adjustable lenses in a head-mounted device may be adjusted when the user is viewing a close object. To allow for intelligent adjustments of the adjustable lenses while minimizing power consumption in the head-mounted device, the head-mounted device may receive sensor data and/or focal point change instructions from a paired electronic device. The paired electronic device may detect a trigger, analyze the user's attention to the paired electronic device, and send focal point change instructions to the head-mounted device based on the obtained information.

Tunable lens in an electronic device controlled using a paired electronic device

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.

Adjusting a tunable lens in an electronic device

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.

Electronic devices with liquid lenses

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.

Display system with virtual image distance adjustment and corrective lenses

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.

User interfaces for adjusting a tunable lens

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.

Electronic devices with adjustable lenses

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.

Digital optical cross-talk compensation systems and methods

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.

Waveguided display system with adjustable lenses

Display panel optical cross-talk compensation systems and methods

A near eye display system can include a first triplet lens arranged in a tile fashion and configured to be associated with a left eye. The near eye display system also can include a second triplet lens arranged in the tile fashion and configured to be associated with a right eye. A multiple display system can be paired with the first triplet lens and the second triplet lens.

Tiled triplet lenses providing a wide field of view

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.

An optical system includes, from an image side to an object side, a first lens having a positive refractive power, a second lens having a positive refractive power, and a third lens having a negative refractive power. The first lens, the second lens, and the third lens form an optical path with the object side facing a screen and the image side adapted to provide an image from the screen to a user. In one aspect, the optical system is adapted to correct at least one of a group of aberrations including astigmatism and field curvature; or, lateral color.
