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: Electronic devices, displays, and methods are provided for performing pixel grouping to enable efficient display operation at higher frame rates and lower image resolutions without sacrificing significant image quality. An electronic display may include a number of rows of display pixels and driving circuitry. The driving circuitry may receive a frame of image data and drive a set of adjacent groups of rows of equal number using the frame of image data. Adjacent groups of rows may respectively include two or more adjacent rows.

Abstract: A pulse width modulation and amplitude modulation driving system for a display panel, including related circuits and methods of operation, are described. In an embodiment, a display panel includes a thin film transistor layer comprising a plurality of subpixel circuits. Each subpixel circuit may include a drive transistor, a comparator, and a switch. A plurality of light emitting diodes (LEDs), such as micro-LEDs, may be connected to the plurality of subpixel circuits. Each subpixel circuit can control an LED based on a current amplitude controlled by the drive transistor and a current pulse width controlled by the comparator and the switch. Other aspects are also described and claimed.

Abstract: An electronic device may include a display and an optical sensor formed underneath the display. The display may have both a full pixel density region and a pixel removal region with a plurality of high-transmittance areas that overlap the optical sensor. The display may include a black masking layer with a plurality of horizontal portions and a plurality of vertical portions that form a grid that defines a plurality of apertures. The black masking layer may additionally include patches in the apertures. The patches may be optimally positioned to mitigate diffraction artifacts in the sensor that operates through the pixel removal region. The patches may have unique sizes and shapes. The display may include first and second pixel removal regions with different black masking layer layouts. The layouts may cause complementary diffraction artifacts such that a single artifact-free image may be constructed using the first and second optical sensors.
