    Abstract: Methods and systems for reducing power consumption of a display link by compacting image data to allow the display link to be deactivated for a longer duration. For instance, pixels that correspond to a preset or default value for a display may be omitted from pixel data sent over the display link. Additionally or alternatively, the display link may be divided into multiple lanes that function independently so that a lane of the display link may be deactivated while other lanes are actively transmitting image data.

    Abstract: Systems and methods are provided for improving displayed image quality of an electronic display that includes a display pixel. The electronic display displays a first image frame directly after a second image frame by applying an analog electrical signal to the display pixel. To facilitate display of the first image frame, circuitry receives image data corresponding to the image frame, in which the image data includes a grayscale value that indicates target luminance of the display pixel; determines expected refresh rate of the first image frame based at least in part on actual refresh rate of the second image frame; determines a pixel response correction offset based at least in part on the expected refresh rate of the first image frame; and determines processed image data by applying the pixel response correction offset to the grayscale value, in which the processed image data indicates magnitude of the analog electrical signal.

    Abstract: A display device may include rows of pixels that displays image data on a display, data lines coupled to the rows of pixels, and a digital-to-analog converter (DAC) that outputs a ramp voltage signal including a data voltage to be depicted on a first pixel of the rows of pixels. The display device may also include a capacitor that receives the ramp voltage signal via the DAC and a circuit that sends a control signal to a circuit component that causes the DAC to couple to the capacitor via one of the data lines for a duration of time that comprises a first time when the ramp voltage signal is below the data voltage and a second time when the ramp voltage signal is approximately equal to the data voltage. The capacitor is coupled to the DAC when the ramp voltage signal is greater than zero.
