Abstract: An actuator assembly includes a primary electrode, a secondary electrode overlapping at least a portion of the primary electrode, and an electroactive polymer layer disposed between the primary electrode and the secondary electrode, where the electroactive polymer layer includes a non-vertical (e.g., sloped) sidewall with respect to a major surface of at least one of the electrodes. The electroactive polymer layer may be characterized by a non-axisymmetric shape with respect to an axis that is oriented orthogonal to an electrode major surface.

Abstract: An example apparatus may include a display and an optical configuration configured to provide an image of a display, for example, in a head-mounted device. An example apparatus may include a display and an optical configuration including a first lens assembly and a second lens assembly. The first lens assembly may include a first lens, a first reflector, and an actuator. The second lens assembly may include a second lens and a second reflector. An example apparatus may include a controller configured to apply at least one electrical signal to the actuator to control the optical power of the first lens. The display light may pass through the actuator, which may be transparent and may include a plurality of actuator layers.

Abstract: A lightguide for conveying image light to an eyebox of a display device includes a tunable grating, e.g. an out-coupling grating for out-coupling the image light from the lightguide. The tunable grating may be tuned or switched to effectively diffract light of a color channel of a color-sequential display. In augmented reality display systems, a lightguide combiner element may include a switchable grating to out-couple the image light only during short time intervals and to not out-couple the image light in between these time intervals. Effectively, the out-coupling grating is present only a portion of overall operation time of the display, which improves the transparency of the combiner element to the outside light and reduces rainbow effects.

Abstract: A pupil-replicating lightguide includes a slab of transparent material, a switchable out-coupling grating for out-coupling portions of image light to propagate towards an eyebox, and a switchable tracking grating for redirecting tracking light carrying an eye image towards an eye tracking camera. One of the two gratings may be turned ON while the other is turned OFF, in a time-sequential manner, allowing the combined use of the pupil-replicating lightguide for carrying image light and eye tracking light.

Abstract: Disclosed devices may include a membrane having a membrane curvature, a substrate, an enclosure (defined at least in part by the membrane and the substrate) enclosing a fluid, a peripheral structure configured to adjust the membrane curvature, and a sensor configured to provide a sensor signal that is a function of the membrane curvature. The device may also include a controller configured to control the membrane curvature using a control signal. For example, the control signal may be provided to at least one actuator. The controller may receive a sensor signal from the sensor and modify the control signal based on the sensor signal. Examples also include associated methods and systems.
