Abstract: A hybrid display may include different display portions with different resolutions. The high resolution display portion may be positioned in a main viewing area for the viewer whereas the low resolution display portion may be positioned in a peripheral viewing area. The high resolution display portion may have a silicon backplane. The low resolution display portion may have a different type of backplane such as a thin-film transistor backplane. The different display portions may optionally share a common organic light-emitting diode layer such that light is emitted from the same plane across both display portions. The high resolution display portion may emit light through a transparent window in the low resolution display portion. A high resolution display may also be formed by separately forming a frontplane and a backplane. Conductive attachment structures such as indium bumps may be used to mechanically and electrically connect the backplane to the frontplane.

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 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: 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 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: Pixels in an organic light-emitting diode (OLED) display may be microcavity OLED pixels having optical cavities. The optical cavities may be defined by a partially transparent cathode layer and a reflective anode structure. The anode of the pixels may include both the reflective anode structure and a supplemental anode that is transparent and that is used to tune the thickness of the optical cavity for each pixel. Organic light-emitting diode layers may be formed over the pixels and may have a uniform thickness in each pixel in the display. Pixels may have a conductive spacer between a transparent anode portion and a reflective anode portion, without an intervening dielectric layer. The conductive spacer may be formed from a material such as titanium nitride that is compatible with both anode portions. The transparent anode portions may have varying thicknesses to control the thickness of the optical cavities of the pixels.

Abstract: Optical systems may have tunable lenses with focal lengths that are adjusted by control circuitry. A display may produce image light that is received by a tunable lens. The display may be transparent so that light from objects can pass through the display and be received by the tunable lens. The tunable lens may include a birefringent lens element and a polarization rotator and may receive light that has been linearly polarized by passing through a linear polarizer. The polarization rotator may be operable in a first state in which the polarization of light passing through the polarization rotator is not rotated and a second state in which the polarization of light passing through the polarization rotator is rotated by 90°. The birefringent lens element may be formed from a cured liquid crystal polymer or other polymer and may have a liquid crystal additive to enhance birefringence.
