Abstract: Electronic devices and methods for compensating for aging or other effects in a display during a non-transmitting state (off state) of the display. Sensing may include emissive element sensing of the display and/or thin film transistor sensing of the display. Compensating for the effects may preserve or increase a uniformity of transmission of the display.

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.

An electronic display may include a display pixel and a bias voltage supply.

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.

Image processing circuitry may generate a compensation value to compensate the image data for cross-talk (e.g., electromagnetic coupling between an electrode of touch sensor circuitry and an electrode of the pixel circuitry) that may cause the voltage variations. Additionally or alternatively, the image processing circuitry may generate another compensation value to compensate the image data for another cross-talk (e.g., electromagnetic coupling between two electrodes of the pixel circuitry). The image processing circuitry may generate the compensated image data based on the first compensation value and/or the second compensation value.

One or more parameters related to hysteresis of transistors in the electronic display are sensed. A correlation device, such as a look-up table, receives the sensed parameter or parameters and the data relating to one or more image frames, and uses this information, at least in part, to output an appropriate compensation signal for the current image frame data. The compensated current image frame data may then be supplied to the electronic display to reduce or eliminate the effects of hysteresis on the displayed image.

Based at least in part on the instantaneous average pixel luminance, the luminance of a subset of pixels of image data of the current image frame may be adjusted, thereby allowing the electronic display to operate at a relatively high brightness level without exceeding a power limit.
