Abstract: Systems, methods, and devices are provided for mitigating visual artifacts by dynamically tuning bias voltages applied to display pixels. An electronic display may include a display pixel and a bias voltage supply. The bias voltage supply may supply a first bias voltage to the display pixel for a first subframe of a frame of image data. The bias voltage supply may supply a different second bias voltage to the display pixel for a second subframe of the frame of image data. This may mitigate certain image artifacts, such as flicker or variable refresh rate luminance difference, that could arise due to display pixel hysteresis that varies across subframes of the image frame.

Abstract: This disclosure provide various techniques for tracking emission profiles on an electronic display. An emission profile may be applied to the electronic display in order to illuminate certain pixels and deactivate (e.g., turn off) certain pixels in the electronic display to facilitate refreshing (e.g., programming with new image data) the deactivated pixels. A real-time row-based average pixel level or average pixel luminance calculation architecture may track the one or more EM profiles to accurately model EM profile behavior, which may enable accurate calculation of the average pixel level or average pixel luminance of the electronic display at any one point in time. The accurate average pixel level or average pixel luminance calculations effectuated by the EM profile tracking may be used to reduce the IR drop, improve real-time peak-luminance control, and improve the performance of under-display sensors, among other advantages.

Abstract: External compensation of display panels may employ measurement or sensing circuitry configured to measure the output of a pixel and compensate for variations.

Systems and methods that compensate for the effects from sensing circuitry and reduce or mitigate the mismatch are described. Systems and methods described herein include compensation circuitry that is capable of employing correction factors to compensate for the effects due to the presence of sensing circuitry. Methods for determining the correction factor are also described.

Abstract: Embodiments presented herein relate to reducing visual artifacts on an electronic display caused by an intra-frame pause. To do so, the intra-frame pause may be divided into smaller intra-frame pause segments. The intra-frame pause segments may be applied to the display during different image frames and/or at different locations on the electronic display. For example, each intra-frame pause segment may be applied to a different location on the electronic display. In some embodiments, multiple intra-frame pause segments may be applied during a single image frame. In some embodiments, the intra-frame pause segments may be applied to various image frames and at various location on the electronic display according to a pattern. To reduce band flickering that may be caused by the different locations of the intra-frame pause segments, an emission duty of one or more rows of pixels of the display may be adjusted.

Abstract: A current-voltage (IV) relationship of a pixel having a diode is initially determined. A first voltage is determined that does not cause the diode to emit light, and a first current across the diode is sensed by applying the first voltage. A predetermined current is determined based on the first voltage and the IV relationship. A ratio is determined based on the first current, a target current, and the predetermined current. A ratio voltage is determined by applying the ratio to a predetermined target voltage. If the first current is less than the predetermined current, then the ratio voltage is applied to supply a target current to the diode. If the first current is greater than the predetermined current, then a second voltage is determined by averaging the first test voltage and the ratio voltage, and the second voltage is applied to supply the target current to the diode.

Abstract: A display may include an array of pixels, where each pixel in the array includes an organic light-emitting diode coupled to associated thin-film transistors. The thin-film transistors may be controlled using at least first and second horizontal scan line signals. Loading different data values into any given row in the array may cause the scan line signals to exhibit varying rise/fall times, which results in horizontal crosstalk and luminance non-uniformity across the display. The rise and fall times of the second scan line signal are crucial, so the second scan line signal is driven by two separate scan line drivers formed on both sides of the display. Only the fall time of the first scan line signal is crucial, so the first scan line signal is driven by only one peripheral scan line driver and is coupled to an auxiliary pull-down circuit that is only activated during the pull-down transition.
