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.

Abstract: An electronic device may include a display having display pixels formed in an active area of the display. The display further includes display driver circuitry for driving gate lines that are routed across the display. A hole such as a through hole, optical window, or other inactive region may be formed within the active area of the display. Multiple gate lines carrying the same signal may be merged together prior to being routed around the hole to help minimize the routing line congestion around the border of the hole. Dummy circuits may be coupled to the merged segment portion to help increase the parasitic loading on the merged segments. The hole may have a tapered shape to help maximize the size of the active area. The hole may have an asymmetric shape to accommodate multiple sub-display sensor components.

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 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: An electronic device may include a display and an optical sensor formed underneath the display. The electronic device may include a locally modified region that overlaps the optical sensor. The locally modified region of the display may have a modification relative to a normal region of the display that does not overlap the optical sensor. The modification may mitigate diffractive artifacts that would otherwise impact the optical sensor that senses light passing through the display. To mitigate diffraction artifacts, the locally modified region of the display may use spatial randomization (e.g., spatial randomization of signal paths and/or spatial randomization of via locations), opaque structures may be formed with circular footprints, a black masking layer may be formed with circular openings, apodization may be used, and/or a phase randomization film may be included.

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: A display may have both a full pixel density region and a pixel removal region with a plurality of high-transmittance areas that overlap an optical sensor. Each high-transmittance area may be devoid of thin-film transistors and other display components. To improve transmission while maintaining satisfactory touch sensing performance, one or more segments of the touch sensor metal in the pixel removal region may have a reduced width relative to the touch sensor metal in the full pixel density region and/or one or more segments of the touch sensor metal in the pixel removal region may be omitted relative to the touch sensor metal in the full pixel density region. To mitigate a different appearance between the pixel removal region and the full pixel density region at off-axis viewing angles, the position of the touch sensor metal in the pixel removal region may be tuned.

Abstract: An organic light-emitting diode display may have thin-film transistor circuitry formed on a substrate. The display and substrate may have rounded corners. A pixel definition layer may be formed on the thin-film transistor circuitry. Openings in the pixel definition layer may be provided with emissive material overlapping respective anodes for organic light-emitting diodes. A cathode layer may cover the array of pixels. A ground power supply path may be used to distribute a ground voltage to the cathode layer. The ground power supply path may be formed from a metal layer that is shorted to the cathode layer using portions of a metal layer that forms anodes, may be formed from a mesh shaped metal pattern, may have L-shaped path segments, and may include laser-deposited metal on the cathode layer. Data lines may be formed from metal layers in the active area to accommodate the rounded corners of the display.
