  • Current protection systems and methods for electronic device displays
    Patent number: 10762856
    Abstract: Aspects of the subject technology relate to electronic devices with displays. A display may include an array of display pixels and control circuitry for operating the display. The control circuitry may determine, based on pixel values for a row of display pixels, that a current in common supply voltage circuitry for the display pixels will exceed a threshold, if the row of display pixels is operated using the pixel values. The control circuitry may modify the pixel values for the row of display pixels to reduce the current in the common supply voltage circuitry and/or prevent the current in the common supply voltage circuitry from exceeding the threshold.
