摘要： An electronic device may be provided with a display. The display may have a display cover layer. The display may have an active area with pixels and an inactive area adjacent to the active area. A reflective layer or a reflective portion of the cover layer may be formed in the inactive area and may have a reflectivity that matches a reflectivity of the active area of the display. The reflective portion may include texture or particles embedded in an ink layer. A PVD layer may be formed on the reflective layer and may have a color that matches a color of the active area. A polarizer layer may also extend across the active areas and inactive areas. In this way, an appearance of the inactive area may match an appearance of the active area when the display is off.

摘要： An electronic device may be provided with a display. The display may have a display cover layer. The display may have an active area with pixels and an inactive area with dummy pixels. The dummy pixels may have structures that are optically matched to the pixels so that the dummy pixels and pixels have similar visual appearances when the display is off. An optical window may be formed in the inactive area. A light-based component such as an ambient light sensor, proximity sensor, or image sensor may be mounted in the electronic device in alignment with the optical window. A polarizer layer may overlap the active and inactive areas of the display. An opening in the polarizer or a bleached unpolarized portion of the polarizer may be aligned with the optical window.

摘要： Electronic devices, storage medium containing instructions, and methods pertain to scanning a display during a sensing phase for the display. One or more parameters pertaining to operation or conditions around the display are obtained. Using the obtained one or more parameters, scanning mode parameters used for sensing are set based at least in part on the obtained one or more parameters. Using the scanning mode parameters, the display is scanned during a sensing phase of the display while reducing the likelihood of visible artifacts.

摘要： 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.

摘要： An electronic device that includes processing circuitry configured to generate a frame of image data that has a frame duration is provided. The electronic device includes a display that has a plurality of pixels. Each of the plurality of pixels displays image data from the frame of image data for a pixel emission period that is less than the frame duration. A first pixel of a column of pixels of the plurality of pixels begins displaying the image data from the frame of image data at a first time for a first duration. A second pixel of the column of pixels that is adjacent to the first pixel begins displaying the image data from the frame of image data at a second time for a second duration. The first and second durations are equal to the pixel emission period. The second time begins after the first duration of time.

摘要： 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.

摘要： 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.

摘要： A mobile electronic device includes a display having a pixel and processing circuitry separate from but communicatively coupled to the display. The processing circuitry prepares image data to send to the pixel and adjusts the image data to compensate for operational variations of the display based on feedback received from the display that describes a present operational behavior of the pixel. The mobile electronic device also includes additional electronic components that affect the present operational behavior of the pixel depending on present operational behavior of the additional electronic components.
