Abstract: An electronic display may include pixel circuitry to display an image based on image data compensated for voltage variations within the pixel circuitry. 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.

Abstract: The present disclosure relates generally to systems and methods that may reduce a reduction in visual artifacts related to hysteresis of a light emitting diode (LED) electronic display. In one example, an electronic device may include a controller. The controller is may provide a signal to a pixel of a display of the electronic device while at least a portion of the display is turned off. The signal may include a first current and a second current. The first current may be designed to increase an ambient temperature corresponding to the pixel. The second current may be generated as part of an active panel conditioning operation. By applying the first current and the second current, hysteresis settling times from the pixel may improve, therefore improving speeds of sensing and compensation operations of the electronic device.

Abstract: Current-voltage shift determination circuitry of a processing core complex coupled to the electronic display determines total current-voltage shift values at a pixel. The current-voltage shift determination circuitry then determines temperature-based current-voltage shift values at the pixel. The current-voltage shift determination circuitry extracts the temperature-based current-voltage shift values from the total current-voltage shift values to determine age-based voltage degradation values. Display compensation circuitry of the processing core complex adjusts display of image data by the pixel based on the age-based voltage degradation values. In this manner, voltage degradation due to pixel aging may be determined separately from current-voltage shift due to temperature, and, as such, be more accurately compensated for, resulting in better display of image data.

The electrical bus may include a digital to analog converter to generate at least some of the analog voltage signals and multiple output buffers to buffer the analog voltage signals. The outputs may be buffered by an output buffer of the output buffers.

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.

Abstract: A display may include an array of organic light-emitting diode display pixels having transistors characterized by threshold voltages subject to transistor variations. Compensation circuitry may be used to sense a current from selected display pixels. A display pixel may include a drive transistor, a gate setting transistor for driving a reference voltage onto the gate terminal of the drive transistor, a data loading and current sensing transistor for connecting the drive transistor to a data/current-sensing line, a light-emitting diode, an emission control transistor coupled between the drive transistor and the diode, and an anode resetting transistor for selectively resetting the anode terminal of the diode. During in-frame current sensing operations, the emission control transistor may be turned off to decouple the drive transistor from the diode, thereby blocking off any residue current and lateral leakage current that may be present at the diode.

A lookup table is generated based on temperatures at the pixel, diode voltages, and target diode currents or luminances at a diode of the pixel. A correction voltage is determined based on a target diode current or luminance, a temperature at the pixel, and the lookup table. A data voltage is applied corresponding to the target diode current or luminance and the correction voltage to the driver transistor.

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.

During data loading, data from display driver circuitry may be supplied, alternately to odd pairs of the data lines and even pairs of the data lines. During sensing, the demultiplexer circuitry may couple a pair of the even data lines to sensing circuitry in the display driver circuitry and then may couple a pair of the odd data lines to the sensing circuitry.

Abstract: Techniques for implementing and/or operating an electronic device, which includes a display pixel that emits light to facilitate displaying an image during an emission period and a data driver coupled to the display pixel via a data line. The data driver generates a data line voltage signal based on image data that indicates target luminance of the display pixel in the image and supplies the data line voltage signal to the data line during a non-emission period preceding the emission period to facilitate writing the image to the display pixel. Additionally, the data driver supplies an intermediate voltage greater than a ground voltage to the data line during the emission period in which the image is displayed to facilitate reducing luminance variation in the image resulting from a leakage current flowing between an internal node of the display pixel and the data line during the emission period.
