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: An electronic device may have a display. The display may include an array of pixels formed on a silicon substrate. Display driver circuitry may be formed in a display driver integrated circuit that outputs display data and other control signals for operating the display. An interposer structure may be included in the electronic device. The interposer structure may be attached to the silicon display substrate and may only partially overlap the silicon display substrate. The display driver integrated circuit may be attached to the interposer structure and provide signals to the display pixels through the interposer structure. In another possible arrangement, the display driver integrated circuit may bridge a gap between the silicon display substrate and the flexible printed circuit. The display driver integrated circuit only partially overlaps the silicon display substrate in this arrangement.

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: 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.
