Abstract: A display may have an array of organic light-emitting diode (OLED) 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 cross-talk, the thickness of at least one of the OLED layers may be reduced. To maintain the optical cavity of the pixels, transparent optical spacer structures may be inserted. Alternatively, the thickness of the anodes can be increased. To accommodate a common prime layer within the OLED layers, the optical spacers or anodes may be separately patterned to have different thicknesses. Grating structures and photonic crystal structures may be embedded as part of the optical spacers to help control emission at selected viewing angles.

Abstract: Visibility of the metal mesh touch electrodes can be mitigated using one or more mitigation techniques. In some examples, the boundary between touch electrodes and/or the boundary between a touch electrode and a routing trace of another touch electrode and/or the boundary between two routing traces can be non-linear. In some examples, dummy cuts can be made within an area of a touch electrode region (e.g., while maintaining the same electrical potential for the touch electrode region). In some examples, notches can be made in the metal mesh. In some examples, the location of cuts and/or notches can be optimized to mitigate visibility of the metal mesh. In some examples, some or all of the visibility mitigations may be used in combination in a touch screen.

Abstract: An electronic device may have a support structure that supports a display and lenses. Each lens may be a reflective lens such as a catadioptric lens that receives polarized image light from the display and provides a corresponding image to an eye box. The display may be an emissive display with pixels that include light-emitting diodes. The light-emitting diodes may be overlapped by a light recycling layer such as a reflective polarizer or cholesteric liquid crystal layer. The light recycling layer recycles emitted light to enhance display efficiency.

Abstract: An electronic device includes a frame and a display stack. The frame defines a first part of an interior volume. The display stack includes a cover attached to the frame. The cover may define a second part of the interior volume. The display stack also includes an array of organic light-emitting diodes (OLEDs) including an array of emissive electroluminescent (EL) regions, and at least one organic photodetector (OPD) disposed between the cover and at least one emissive EL region in the array of emissive electroluminescent regions. The at least one emissive EL region emits light through the at least one OPD. In alternative embodiments, the OLEDs may be stacked on the OPDs, or the OLEDs and OPDs may be interspersed with each other instead of stacked.
