Abstract: An electronic device includes an electronic display having an active area comprising a pixel. The electronic device also includes processing circuitry configured to receive image data and predict a change in threshold voltage associated with a transistor of the pixel based at least in part on the image data. Furthermore, the processing circuitry is configured to adjust the image data to generate adjusted image data based at least in part on the predicted change in threshold voltage.

Abstract: To reduce the amount of space occupied in the inactive area of a display by gate driver circuitry, at least a portion of the gate driver circuitry may be positioned in the active area of the display. To accommodate the gate driver circuitry, emissive sub-pixels may be laterally shifted relative to corresponding thin-film transistor sub-pixels. This allows for the thin-film transistor sub-pixels to be grouped adjacent to the central area of the active area, leaving room along an edge of the active area to accommodate one or more additional display components such as gate driver circuitry or fanout portions of data lines.

Abstract: A system includes an electronic display panel that has a plurality of pixels configured to depict frames of image data. The electronic display also includes display driver circuitry configured to, for a first frame of image data representing first image content, modify a gate-to-source voltage of a transistor of a first pixel of the plurality of pixels to a content-dependent first gate-to-source voltage. Additionally, after modifying the gate-to-source voltage to the first gate-to-source voltage, the display driver circuitry is configured to program the first pixel by modifying the gate-to-source voltage to a gate-to-source programming voltage that differs from the first gate-to-source voltage and is based on image data associated with the pixel from the first frame of the image data. Furthermore, the display driver circuitry is configured to cause the plurality of pixels to emit light.

Abstract: A display may include an array of pixels. Each pixel in the array may include a drive transistor, emission transistors, a data loading transistor, a gate voltage setting transistor, an initialization transistor, an anode reset transistor, a storage capacitor, and an optional current boosting capacitor coupled in series with an isolation transistor. A data refresh may include a initialization phase, a threshold voltage sampling phase, and a data programming phase. The threshold voltage sampling phase can be substantially longer than the data programming phase to decrease a current sampling level during the threshold voltage sampling phase, which helps reduce the display luminance sensitivity to temperature variations. During a data refresh, the isolation transistor can be turned on to provide current boosting. During emission periods, the isolation transistor is turned off to prevent cathode noise from potentially coupling through to one or more direct-current voltage nodes in the pixel.
