    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: An electronic device may include a display, a display driver integrated circuit for controlling the display, and a system processor for running one or more applications on the electronic device. The display may be operated in at least a video mode and a command mode. In the video mode, the system processor operates as the primary timing circuit while the display driver integrated circuit operates as the secondary timing circuit. In the command mode, the display driver integrate circuit operates as the primary timing circuit while the system processor operates as the secondary timing circuit. The system processor may be configured to switch between video mode and the command mode without turning off the electronic device and without turning off the display driver integrated circuit. If desired, the display can be temporarily turned off during a mode switching event to hide potential front of screen artifacts.

    Abstract: This disclosure provide various techniques for tracking emission profiles on an electronic display. An emission profile may be applied to the electronic display in order to illuminate certain pixels and deactivate (e.g., turn off) certain pixels in the electronic display to facilitate refreshing (e.g., programming with new image data) the deactivated pixels. A real-time row-based average pixel level or average pixel luminance calculation architecture may track the one or more EM profiles to accurately model EM profile behavior, which may enable accurate calculation of the average pixel level or average pixel luminance of the electronic display at any one point in time. The accurate average pixel level or average pixel luminance calculations effectuated by the EM profile tracking may be used to reduce the IR drop, improve real-time peak-luminance control, and improve the performance of under-display sensors, among other advantages.

    Abstract: A display device may include a plurality of pixels that may display image data on a display. The display device may also include a circuit that may receive pixel data including a gray level for at least one pixel of the plurality of pixels. The circuit may then receive an emission clock signal using a clock circuit based on the pixel data, such that the emission clock signal may cause the at least one pixel to receive a current for an amount of time based on the gray level. The circuit may then gate off the clock circuit after the amount of time.

    Abstract: Systems and methods are provided for differential sensing (DS), difference-differential sensing (DDS), correlated double sampling (CDS), and/or programmable capacitor matching to reduce display panel sensing noise. An electronic device may include one or more processors and an electronic display. The one or more processors may generate image data and adjust the image data based at least in part on display sensing feedback. The electronic display may employ sensing circuitry that obtains the display sensing feedback at least in part by applying test data to a pixel of a column of an active area of the display and differentially senses an electrical value of the pixel in comparison to a reference signal from a different column. This reference signal may provide a common mode noise reference, which is removed by the differential sensing and thereby enhances a quality of the sensed electrical value of the pixel.
