Abstract: An electronic device may have a display such as an organic light-emitting diode display. The display may have an active area formed from an array of pixels with light-emitting diodes. The light-emitting diodes may be formed from an organic layer containing emissive material between an anode layer and a cathode layer. Apertures may be formed in the active area of the display. The apertures may allow light to pass to light-sensitive components under the display. A polarizer may overlap the display and may have a bleached area that forms part of a camera aperture. Light may pass through the camera aperture to a camera under the display. The display may have an array of apertures that allow light to pass to a light-sensitive fingerprint sensor under the display.

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: Aspects of the subject technology relate to electronic devices with displays. The display includes an array of display pixels and one or more display-light sensors that monitor the display light generated by the display pixels. Using the display-light sensors, corrections to control signals for the display pixels can be provided to correct for array non-uniformities and/or pixel degradation over time. The display-light sensors may be provided in an array of display-light sensors mounted parallel to the array of display pixels. The array of display-light sensors can be in-plane with the display pixels or vertically displaced from the display pixels. The display-light sensors may be prevented from receiving non-display light such as ambient light.

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: A display may have an array of pixels. Each pixel may have a light-emitting diode such as an organic light-emitting diode. The organic light-emitting diodes may each have an anode that is coupled to a thin-film transistor pixel circuit for controlling the anode. Transparent windows may be formed in the display. The windows may be formed by replacing subpixels in some of the pixels with transparent windows. When subpixels are replaced by transparent windows, adjacent subpixels may be overdriven to compensate for lost light from the replaced subpixels. Adjacent subpixels may also be enlarged to help compensate for lost light. An array of electrical components such as an array of light sensors may be aligned with the transparent windows and may be used to measure light passing through the transparent windows.

Abstract: Systems and electronic displays with improved contrast even under bright-light conditions are provided. Such an electronic display may include a self-emissive pixel (e.g., OLED or μ-LED) with a corresponding liquid crystal switchable retarder pixel. A liquid crystal layer of the switchable retarder pixel may be tuned to an “on” state or an “off” state. In the “on” state, the switchable retarder pixel may allow outside light that enters the pixel to reflect back out of the pixel. This may add to the amount of light that appears to be emitted from that pixel. In the “off” state, the switchable retarder pixel may block the outside light that enters the pixel from reflecting back out of the pixel. This may reduce the amount of light that appears to be emitted from that pixel. Selectively controlling the switchable retarder pixels may allow for increased contrast even under bright-light conditions.
Abstract translation: 提供了即使在明亮的条件下也能提供对比度的系统和电子显示器。 这样的电子显示器可以包括具有相应的液晶可切换延迟器像素的自发射像素（例如，OLED或μ-LED）。 可切换延迟器像素的液晶层可以被调谐到“接通”状态或“断开”状态。 在“开”状态下，可切换延迟器像素可以允许进入像素的外部光反射回像素。 这可能增加似乎从该像素发射的光量。 在“关闭”状态下，可切换延迟器像素可以阻挡进入像素的外部光线从像素反射回来。 这可能减少似乎从该像素发射的光量。 选择性地控制可切换延迟器像素可以允许即使在明亮的条件下也增加对比度。

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.
