Abstract: A display may include an array of pixels. Each pixel in the array includes an organic light-emitting diode coupled to associated thin-film transistors. The diode may be coupled to drive transistor circuitry, a data loading transistor, and emission transistors. The drive transistor circuitry may include at least two transistor portions connected in series. The data loading transistor has a drain region connected to a data line and a source region connected directly to the drive transistor circuitry. The data line may be connected to and overlap the drain region of the data loading transistor. The data line and the source region of the data loading transistor are non-overlapping to reduce row-to-row crosstalk.

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: A light emitter that operates through a display may cause display artifacts, even when the light emitter operates using non-visible wavelengths. Display artifacts caused by a light emitter that operates through a display may be referred to as emitter artifacts. To mitigate emitter artifacts, operating conditions for a display frame may be used to determine an optimal firing time for the light emitter during that display frame. The operating conditions used to determine the optimal firing time may include emitter operating conditions, display content statistics, display brightness, temperature, and refresh rate. Operating conditions from one or more previous frames may be stored in a frame buffer and may be used to help determine the optimal firing time for the light emitter during a display frame. Pixel values for the display may be modified to mitigate emitter artifacts.
