Abstract: Systems, methods, and devices are described that may mitigate pixel and touch crosstalk noise. A touch processing system may compensate touch scan data to reduce the noise based on a luminance value. An image processing system may determine the luminance value based on image data and a display brightness value of an electronic display. Using the compensated touch scan data, the touch processing system may determine a proximity of a capacitive object to at least one touch sense region of the electronic display.

Abstract: To reduce overall power consumption for an electronic display power management integrated circuit (PMIC), one of multiple electric power converters and/or electric power regulators may be selected based on an electrical load (e.g., due to the total brightness of the content displayed) on the electronic display at a given moment. In some embodiments, the PMIC may include a less efficient heavy load converter designed with high-current handling capability and a more efficient light load (e.g., low current) converter with lower current handling capability. A controller may dynamically select between the converters depending on a present load or an expected load on the electronic display.

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: In an embodiment, an electronic device includes an electronic display. The electronic display provides a programmable latency period in response to receiving a first image frame corresponding to first image frame data. The electronic display also displays the first image frame after the programmable latency period and during display of the first image frame, receives a second image frame corresponding to second image frame data. The electronic display also repeats display of the first image frame in response to receiving the second image frame.

Abstract: A system may include an electronic display panel having pixels, where each pixel emits light based on a respective programming signal applied to the pixel. The system may also include processing circuitry to determine a respective control signal upon which the respective programing signal for each pixel is based. The processing circuitry may determine each respective control signal based at least in part on approximations of respective pixel brightness-to-data relationship as defined by a function having variables stored in memory accessible to the processing circuitry.

Abstract: Circuits, methods, and apparatus that may estimate the power being consumed by an OLED display screen of an electronic device, may provide further information about that power usage, may modify or change functions performed by the electronic device based on that power usage, and may inform an application's developer about the amount of power being used by the electronic device while the electronic device is running the application. One example may estimate the power being used by an OLED display screen of an electronic device by determining the content of images being displayed during a duration. The estimated power may then be presented to a user. The estimated power may be used in decisions to modify or change parameters of the screen or other device components.

Abstract: Aspects of the subject technology relate to pulsed backlight operation for a display backlight. Backlight pulse patterns are provided that include steady state pulse patterns to be applied during operation of a liquid crystal display unit of the display at a corresponding frame rate. The backlight pulse patterns can be arranged to prevent visible artifacts such as flicker or strobing, particularly at or near a transition between LCD frame rates. In some scenarios, transition pulse patterns are provided.

Abstract: A system is disclosed. The system can comprise drive circuitry included in a first component of the system, the drive circuitry configured to drive a first touch electrode on a touch sensor panel. The system can also comprise a driving line configured to couple an output of the drive circuitry to the first touch electrode. The system can also comprise a feedback line configured to couple the output of the drive circuitry to an input of the drive circuitry, wherein a first end of the feedback line is coupled to the input of the drive circuitry at the first component, and a second end of the feedback line is configured to be coupled to the output of the drive circuitry at a second component, different from the first component, of the system.

Abstract: An electronic device may have a camera and a display. The display may be configured to display virtual reality content for a user in which no real-world content from the camera is displayed or mixed reality content in which a combination of real-world content from the camera and overlaid virtual reality content is displayed. Control circuitry in the device may adjust the display and camera while transitioning between virtual reality and mixed reality modes. The control circuitry may reconfigure the camera to exhibit a desired frame rate immediately upon transitioning from virtual reality mode to mixed reality mode. Transitions between modes may be accompanied by smooth transitions between frame rates to avoid visible artifacts on the display. The camera frame rate may be synchronized to the display frame rate for at least part of the transition between the virtual reality and mixed reality modes.
