Abstract: An electronic device may have a display with an array of pixels. The device may have an array of components such as an array of light sensors for capturing fingerprints of a user through an array of corresponding transparent windows in the display. A capacitive touch sensor, proximity sensor, force sensor, or other sensor may be used by control circuitry in the device to monitor for the presence of a user's finger over the array of light sensors. In response, the control circuitry can direct the display to illuminate a subset of the pixels, thereby illuminating the user's finger and causing reflected light from the finger to illuminate the array of light sensors for a fingerprint capture operation. The display may have display driver circuitry that facilitates the momentary illumination of the subset of pixels with uniform flash data while image data is displayed in other portions of the display.

Abstract: A display may have an active area that includes display pixels. The display may include an inactive notch region that extends into the active area. Data lines may provide image data from display driver circuitry to the display pixels. The image data may include data signals that correspond to portions of the display that do not include pixels, such as the inactive notch region. The null data signals may cause nonuniformities in the displayed image. The null data signals may be adjusted to minimize the nonuniformities. Null data signals corresponding to the inactive notch region may be adjusted to have gray levels that gradually decrease with distance from the border between the inactive notch and the active area. All of the data signals corresponding to the inactive notch may be set to a uniform gray level.

Abstract: An electronic device may have a display with an array of pixels that display images for a user. The electronic device may have an ambient light sensor for gathering ambient light information. A subset of the pixels in the array of pixels may overlap the ambient light sensor so that ambient light passing through the subset of pixels may be measured. Each pixel may have an emission enable transistor coupled in series with a light-emitting diode. Control circuitry in the electronic device may disable the subset of pixels to reduce stray light during ambient light measurements while enabling remaining pixels in the array of pixels to display an image. Ambient light sensor circuitry may gather ambient light sensor measurements over one or more periods by using transfer transistors to transfer change from the photodetectors to charge storage capacitors formed from floating diffusions in a common substrate.

Abstract: An electronic device is provided. The electronic device includes a display that is configured to show content that includes a plurality of frames. The plurality of frames includes a first frame that is associated with a pre-transition value. The plurality of frames also includes a second frame that is associated with a current frame value that corresponds to a first luminance. Additionally, the electronic device is configured to determine an overdriven current frame value corresponding to a second luminance that is greater than the first luminance. The electronic device is also configured to display the second frame using the overdriven current frame value.
