    Abstract: Aspects of the subject technology relate to electronic devices with displays. A display may include an array of display pixels each having a drive transistor and an organic light-emitting diode. A pulse-width-modulated current may be provided to the organic light-emitting diode during each display frame to compensate for an on-bias compensation applied to the drive transistor between display frames. The pulse-width-modulated current may be provided with a pulse-width-modulation ratio that decreases over the course of each display frame. The decrease of the pulse-width-modulation ratio for each display frame may be determined based on a peak luminance for that display frame. The reduction in flicker provided by the pulse-width-modulated current may facilitate operation of the display with a reduced refresh rate, thereby reducing power consumption by the display.

    Abstract: One embodiment describes an electronic display. The electronic display includes display driver circuitry that displays at least a first image frame and a second image frame on the electronic device using a first display pixel and a second display pixel. The electronic display also includes touch sensing circuitry that detects user interaction with the electronic display. A timing controller of the electronic display determines at least a first insertion time for a first intra-frame pause for the first image frame and a second insertion time for a second intra-frame pause for the second image frame. The first and second intra-frame pauses are periods where the display driver circuitry is pauses rendering of image data to allow the touch sensing circuitry to detect user interaction. The insertion times for the first and second intra-frame pauses are varied from one another. The timing controller inserts the first intra-frame pause during rendering of the first image frame at the first insertion time and inserts the second intra-frame pause during rendering of the second image frame at the second insertion time.

    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. 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 implement a physically derived circuit model of the pixels. A charge accumulation input response matrix and a charge accumulation state response matrix for the model may be stored in look-up table circuitry and used in computing a current charge accumulation state based on current pixel voltage information and previous state information. The impact of temperature, backlight illumination level, frame duration, and other factors may be taken into account in evaluating the current charge accumulation state.

    Abstract: Methods and devices employing circuitry for dynamically adjusting bandwidth control of a display interface are provided. The display interface or image content is dynamically adjusted to support both high-speed image data (e.g., 120 Hz image data) and lower-speed content (e.g., 60 Hz content). For example, in some embodiments, additional pixel pipelines and/or processing lanes may be activated during the rendering of high-speed image data, but not during the rendering of low-speed image data. Additionally or alternatively, high-speed image data, but not low-speed data, may be compressed to render high-speed content over an interface that supports only low-speed content.

    Abstract: Systems and methods are provided for adjusting and displaying image data to account for variable common voltage error across separate common electrode sub-plates. The image data may be adjusted based on a common mode common voltage error on a common voltage line coupled to more than one different common electrode sub-plate. Each common electrode sub-plate may carry a common voltage that varies depending on values of the image data programmed to pixels associated with that common electrode sub-plate.

    Abstract: This application relates to methods and apparatus for refreshing a display device at various frequencies. Specifically, multiple areas of the display device can be refreshed concurrently at different frequencies. In this way, when static content is being displayed in certain areas of the display device, those certain areas can be refreshed at a lower rate than areas displaying dynamic content such as video or animation. By refreshing at lower rates, the energy consumed by the display device and subsystems associated with the display device can be reduced. Additionally, processes for reducing flicker when refreshing the display device at different refresh rates are disclosed herein.
