  • Patent number: 11158256
    Abstract: A display may include an array of organic light-emitting diode display pixels having transistors characterized by threshold voltages subject to transistor variations. Compensation circuitry may be used to sense a current from selected display pixels. A display pixel may include a drive transistor, a gate setting transistor for driving a reference voltage onto the gate terminal of the drive transistor, a data loading and current sensing transistor for connecting the drive transistor to a data/current-sensing line, a light-emitting diode, an emission control transistor coupled between the drive transistor and the diode, and an anode resetting transistor for selectively resetting the anode terminal of the diode. During in-frame current sensing operations, the emission control transistor may be turned off to decouple the drive transistor from the diode, thereby blocking off any residue current and lateral leakage current that may be present at the diode.

  • Patent number: 11126295
    Abstract: An electronic device with a touch-sensitive surface displays a user interface of a first software application that is updated at a first display rate. While displaying a first frame of the user interface in accordance with the first display rate, the device detects respective movement of a touch input across the touch-sensitive surface. An application-independent touch processing module of the device selects a respective touch location of the touch input that was detected during the respective movement to identify as a representative touch location for the respective movement based on touch-processing criteria for the first software application, and sends to an application-specific portion of the first software application touch location information for the touch input that identifies the respective touch location as the representative touch location for the respective movement. The first software application updates the user interface in accordance with the touch location information.
