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 organic light-emitting diode (OLED) display may have an array of organic light-emitting diode pixels that each have OLED layers interposed between a cathode and an anode. Voltage may be applied to the anode of each pixel to control the magnitude of emitted light. The conductivity of the OLED layers may allow leakage current to pass between neighboring anodes in the display. To reduce leakage current and the accompanying cross-talk in a display, the pixel definition layer may disrupt continuity of the OLED layers. The pixel definition layer may have an undercut to disrupt continuity of some but not all of the OLED layers. The undercut may be defined by three discrete portions of the pixel definition layer. The undercut may result in a void that is interposed between different portions of the OLED layers to break a leakage path formed by the OLED layers.

Abstract: An electronic device such as a head-mounted device may have displays. The display may have regions of lower (L) and higher (M, H) resolution to reduce data bandwidth and power consumption for the display while preserving satisfactory image quality. Data lines may be shared by lower and higher resolution portions of a display or different portions of a display with different resolutions may be supplied with different numbers of data lines. Data line length may be varied in transition regions between lower resolution and higher resolution portions of a display to reduce visible discontinuities between the lower and higher resolution portions. The lower and higher resolution portions of the display may be dynamically adjusted using dynamically adjustable gate driver circuitry and dynamically adjustable data line driver circuitry.

Abstract: An electronic device may have a display. The display has pixels configured to display an image. The display is mounted in a housing. The housing may include head-mounted support structures configured to support the display for viewing through lenses. The pixels of the display may be covered by a layer of thin-film encapsulation. The thin-film encapsulation may be covered with a cover layer such as a glass cover layer that is attached to the thin-film encapsulation layer by a layer of adhesive. To suppress internal light reflections, the display may include reflection suppression structures. The reflection suppression structures may include an antireflection layer and/or polarizer and waveplate layers. The reflection suppression structures may be formed on an outwardly facing surface of the cover layer and/or between the thin-film encapsulation layer and the cover layer.

Abstract: A liquid crystal display may have main column spacers and subspacer column spacers. The column spacers may have cross shapes formed from overlapping perpendicular rectangular column spacer portions respectively located on a color filter layer and a thin-film transistor layer. The column spacers may have a hybrid configuration in which some of the rectangular portions on the thin-film transistor layer extend vertically and some extend horizontally. Column spacers may be formed from planarization layer material, may be formed from locally thickened portions of a planarization layer, and may have circular shapes.

The conductivity of the OLED layers may allow leakage current to pass between neighboring anodes in the display.

The pixel definition layer may have a steep sidewall, a sidewall with an undercut, or a sidewall surface with a plurality of curves to disrupt continuity of the OLED layers. A control gate that is coupled to a bias voltage and covered by gate dielectric may be used to form an organic thin-film transistor that shuts the leakage current channel between adjacent anodes on the display.

Abstract: Display panel configurations are described in which a pixel-level integrated black matrix layer is combined with an elliptical polarizer. The elliptical polarizer may allow for increased transmission of emissive LEDs in the display panel, while the black matrix layer may mitigate internal reflection of ambient light.

Abstract: An electronic device may be provided with a display such as a liquid crystal display. The liquid crystal display may have a color filter layer, a thin-film-transistor layer, and a layer of liquid crystal material between the color filter layer and the thin-film-transistor layer. A lower polarizer may be formed under the thin-film-transistor layer. An upper polarizer may be formed on the color filter layer. A shielding antireflection layer may be formed on the upper polarizer. The shielding antireflection layer may serve both as a shielding layer that protects against display damage due to electrostatic charge and as an antireflection coating that helps to minimize reflections from the surface of the display. The shielding antireflection layer may include low and high index of refraction layers and a conductive layer such as a transparent conductive oxide layer that provides shielding.
