    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.

    IPC: G09G3/3275

    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 be provided with a display. A content generator may generate frames of image data to be displayed on the display. The display may have an array of pixels that emit light to display images. The pixels may contain light-emitting devices such as organic light-emitting diodes, quantum dot light-emitting diodes, and light-emitting diodes formed from discrete semiconductor dies. As a result of aging, the light producing capabilities of the light-emitting devices may degrade over time. The electronic device may have a temperature sensor that gathers temperature measurements. A pixel luminance degradation compensator may apply compensation factors to uncorrected pixel luminance values associated with the frames of image data to produce corresponding corrected pixel luminance values for the display. The compensation factors may be based on aging history information such as pixel luminance history and temperature measurements.

    Abstract: Systems and methods for improving perceived image quality of an electronic display, which includes a co-located sub-pixel that controls luminance of a first color component and an offset sub-pixel that controls luminance of a second color component. A display pipeline communicatively coupled to the electronic display determines image data, which indicates target luminance of the first, the second, and a third color component at an image pixel; determines edge parameters, which indicate whether an edge is expected to be present at the offset sub-pixel, based on a difference metric between a first image pixel block around the offset sub-pixel and a second image pixel block offset from the first image pixel block; and determines offset sub-pixel image data by filtering an image pixel group around the offset sub-pixel based at least in part on the edge parameters, wherein the offset sub-pixel image data indicates target luminance of the offset sub-pixel.

    Abstract: An electronic device that includes a display is provided. The display may have a brightness that is controlled using a series of cascaded digital-to-analog converter circuits. The display may be calibrated at a series of predetermined display brightness settings. For display brightness settings that fall between two consecutive display brightness settings in the series of predetermined display brightness settings, voltage interpolation operations may be performed to obtain the corresponding display brightness settings. Performing voltage interpolations instead of digital brightness setting interpolation helps minimize luminance jumps and unexpected color shifts when adjusting the brightness of the display.

    Abstract: An electronic device includes a transparent surface, a light emitting device that emits light through the transparent surface, and a light sensor for receiving ambient light and providing an ambient light value. A retarder and a linear polarizer are placed between the transparent surface and the light emitting device. The retarder and linear polarizer may attenuate internal reflections from the transparent surface. The light sensor may have two channels and a second linear polarizer may attenuate the ambient light directed toward a second channel. A second retarder may be used with the second linear polarizer to attenuate the ambient light directed toward the second channel. A light detection circuit may use the difference between the two channels of the light sensor to provide the ambient light value.
