    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. In some scenarios, interference signals from other components of the electronic device or additional external devices can couple to the control circuitry for the display and cause distortions in displayed data. Display frames may be displayed by an electronic device display with a varying phase. The varying phase display frames may each include a distortion pattern that also varies from frame to frame due to the varying phase. The varying distortion patterns may average out or visibly cancel when viewed by a user such that no visible artifact of the interference signal is seen by the user. The varying phase can be actively tuned to the interference signal if desired.

    Abstract: Systems and methods for operating a display by dynamically determining a refresh rate for the display. In certain implementations, a processor determines a number of pixels having medium grayscale levels from a histogram for the image. If the number does not exceed a threshold, the processor sets a refresh rate for the display to a first refresh rate. In certain implementations, if the number exceeds a threshold, the processor may set the refresh rate for the display to a second refresh rate. Moreover, the first refresh rate may be lower than the second threshold. In some implementations, the image may be analyzed by subdividing the image into blocks and determining a refresh rate based on grayscale levels or distributions in the blocks. Based on the analysis of the blocks, a corresponding refresh rate may be selected.

    Abstract: An electronic device may generate content that is to be displayed on a display. The display may have an array of liquid crystal display pixels for displaying image frames of the content. The image frames may be displayed with positive and negative polarities to help reduce charge accumulation effects. A charge accumulation tracker may analyze the image frames to determine when there is a risk of excess charge accumulation. The charge accumulation tracker may analyze information on gray levels, frame duration, and frame polarity. The charge accumulation tracker may compute a charge accumulation metric for entire image frames or may process subregions of each frame separately. When subregions are processed separately, each subregion may be individually monitored for a risk of excess charge accumulation.

    Abstract: An electronic device may contain clock circuits, transmitters, and other circuits that serve as sources of noise signals. The noise signals may be characterized by a noise spectrum. The noise spectrum produced by a noise source can be adjusted by adjusting spread spectrum clock circuitry in a clock circuit, by adjusting data scrambling circuitry in a transmitter circuit, or by making other dynamic adjustments to the circuitry of the electronic device. During operation of the electronic device, sensitive circuitry in the device such as wireless receiver circuitry may be adversely affected by the presence of noise from a noise source in the device. Based on information such as which receiver bands and/or channels are being actively received and target sensitivity levels for the receiver circuitry, control circuitry within the electronic device can determine in real time how to minimize interference between the noise source and the wireless receiver circuitry.
