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: An electronic device includes processors that generate image data. The electronic device also includes an electronic display that displays the image data over a first frame duration by programming a first row of display pixels with the image data. The electronic display also displays the image data over the first frame duration by causing the first row of display pixels to emit light for an emission duration that is based at least in part on a first luminance of the image data. The electronic display further displays the image data over the first frame duration by resetting the first row of pixels before an end of the first frame duration.

Abstract: Systems and methods are described herein to control brightness based on image content or other inputs to a display system. A dual-control system may integrate both slow control operations and fast control operations into a cohesive brightness management system. By using both shorter-term (e.g., fast control) and longer-term (e.g., slow control) brightness adjustment operations, the electronic device may quickly respond to high luminance and high brightness situations that may cause burn-in into the display, image artifacts, or other damage. Responding quickly to these high consumption situations may prevent damage or perceivable upset to an ongoing process, among other benefits.

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 display may include pixel circuitry to display an image based on image data compensated for voltage variations within the pixel circuitry. Image processing circuitry may generate a compensation value to compensate the image data for cross-talk (e.g., electromagnetic coupling between an electrode of touch sensor circuitry and an electrode of the pixel circuitry) that may cause the voltage variations. Additionally or alternatively, the image processing circuitry may generate another compensation value to compensate the image data for another cross-talk (e.g., electromagnetic coupling between two electrodes of the pixel circuitry). The image processing circuitry may generate the compensated image data based on the first compensation value and/or the second compensation value.

Abstract: Electronic devices, storage medium containing instructions, and methods pertain to cancelling noise that results from application of clocks/clock drivers of a display. The electronic display may inject counter noise into the cathode. For example, the counter noise may be injected via a sensing layer, via unused clocks, and/or via a power rail of the display.
