摘要： 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.

摘要： A data processing system can store a long-term history of pixel luminance values in a secure memory and use those values to create burn-in compensation values that are used to mitigate burn-in effect on a display. The long-term history can be updated over time with new, accumulated pixel luminance values.

摘要： Systems and methods for improving perceived image quality of an electronic display, which includes a display region with a rounded border and a display pixel at a pixel position adjacent the rounded border. A display pipeline communicatively coupled to the electronic display receives first image data that indicates target luminance at the pixel position in a rectangular image frame; determines a gain value associated with the pixel position from a gain map, in which the gain value is inversely proportional to distance between the display pixel and the rounded border; determines second image data that indicates target luminance of the display pixel by processing the first image data based at least in part on the gain value; and outputs the second image data to the electronic display to facilitate displaying a non-rectangular portion of the image frame on the display region.
