Abstract: An electronic device display may have an active area with pixels. An optical sensor may be formed under a sensor region in the active area. During operation, ambient light and/or other light associated with the optical sensor may pass through the sensor region. To ensure that the light for the optical sensor can pass through the display, the display may have one or more layers with sensor openings such as a metal layer and a pressure sensitive adhesive layer that attaches the metal layer to the pixels of the display. To help minimize visibility of the openings in the sensor region, the pressure sensitive adhesive layer may be configured to have a reflectivity that matches the appearance of the display in the sensor region to surrounding areas. Undesired light output uniformity can be reduced by ensuring that the substrate material in the display has a low light absorption coefficient.

Abstract: An electronic device may have a display with an active area configured to display images and an inactive area that is free of pixels and that does not display images. Touch sensor sense lines may have portions located in the active area and portions located in the inactive area. The active and inactive areas may be characterized by respective reflectivity values. To match the reflectivities of the active and inactive areas and thereby avoid undesired visually distinguishable differences in the appearances of these areas, the touch sensor circuitry in the inactive areas may be configured to match the reflectivity values of the active and inactive areas. Sense line portions in the inactive area may have metal traces of enhanced reflectivity and/or uneven surface topology to enhance ambient light reflections through a circular polarizer that overlaps the active and inactive areas.

Abstract: A display may include an active area with a first region and a second region. The first region may overlap an input-output component such as a camera and may have a higher transparency than the second region. The first region may have a lower pixel density than the second region. Signal lines that pass through the first region may have transparent portions that overlap the first region and opaque portions that overlap the second region. To mitigate artifacts caused by high resistance of the transparent portions of the signal lines, the signal lines may include supplemental opaque portions that are electrically connected in parallel to the transparent portions and that are routed through the second region around the first region.

Abstract: A light emitter that operates through a display may cause display artifacts, even when the light emitter operates using non-visible wavelengths. To mitigate artifacts caused by a light emitter operating through a display, the display may have a higher density of thin-film transistor sub-pixels than emissive sub-pixels. This allows for a region in the display to include emissive sub-pixels but be free of thin-film transistor sub-pixels. The light emitter may operate through this region in the display. Additionally, to reduce the amount of space occupied in the inactive area of a display by gate driver circuitry, at least a portion of the gate driver circuitry may be positioned in the active area of the display. To accommodate the gate driver circuitry, emissive sub-pixels may be laterally shifted relative to corresponding thin-film transistor sub-pixels.

Abstract: An electronic device may include a display and an optical sensor formed underneath the display. The electronic device may include a plurality of transparent windows that overlap the optical sensor. The resolution of the display panel may be reduced in some areas due to the presence of the transparent windows. To mitigate diffraction artifacts, a first sensor (13-1) may sense light through a first pixel removal region having transparent windows arranged according to a first pattern. A second sensor (13-2) may sense light through a second pixel removal region having transparent windows arranged according to a second pattern that is different than the first pattern. The first and second patterns of the transparent windows may result in the first and second sensors having different diffraction artifacts. Therefore, an image from the first sensor may be corrected for diffraction artifacts based on an image from the second sensor.

Abstract: An organic light-emitting diode display may have rounded corners. A negative power supply path may be used to distribute a negative voltage to a cathode layer, while a positive power supply path may be used to distribute a positive power supply voltage to each pixel in the display. The positive power supply path may have a cutout that is occupied by the negative power supply path to decrease resistance of the negative power supply path in a rounded corner of the display. To mitigate reflections caused by the positive power supply path being formed over tightly spaced data lines, the positive power supply path may be omitted in a rounded corner of the display, a shielding layer may be formed over the positive power supply path in the rounded corner, or non-linear gate lines may be formed over the positive power supply path.

Abstract: An electronic device includes a display and a sensor underneath the display. The display has a full pixel density region and a reduced pixel density region. Compared to pixels in the full pixel density region, pixels in the reduced pixel density region can be controlled using overdriven power supply voltages, overdriven scan control signals, different initialization and reset voltages, and can include capacitors and transistors with different physical and electrical characteristics. Gate drivers provide scan signals to pixels in the full pixel density region, whereas overdrive buffers provide overdrive scan signals to pixels in the reduced pixel density region. The pixels in the full pixel density region and the pixels in the reduced pixel density region can be controlled using different black level or gamma settings for each color channel and can be adjusted physically to match luminance, color, as well as to mitigate differences in temperature and aging impact.

Abstract: An electronic device may include a display and a sensor under the display. The display may include an array of subpixels for displaying an image to a user of the electronic device. At least a portion of the array of subpixels may be selectively removed in a pixel removal region to improve optical transmittance to the sensor through the display. The pixel removal region may include a plurality of pixel free regions that are devoid of thin-film transistor structures, that are devoid of power supply lines, that have continuous open areas due to rerouted row/column lines, that are partially devoid of touch circuitry, that optionally include dummy contacts, and/or have selectively patterned display layers.

Abstract: A light emitter that operates through a display may cause display artifacts, even when the light emitter operates using non-visible wavelengths. Display artifacts caused by a light emitter that operates through a display may be referred to as emitter artifacts. To mitigate emitter artifacts, operating conditions for a display frame may be used to determine an optimal firing time for the light emitter during that display frame. The operating conditions used to determine the optimal firing time may include emitter operating conditions, display content statistics, display brightness, temperature, and refresh rate. Operating conditions from one or more previous frames may be stored in a frame buffer and may be used to help determine the optimal firing time for the light emitter during a display frame. Pixel values for the display may be modified to mitigate emitter artifacts.
