Abstract: A display may include an array of pixels. Each pixel in the array includes an organic light-emitting diode coupled to a drive transistor, a data loading transistor, a first capacitor for storing data charge, and a second capacitor. During a data programming phase, the data loading transistor may be activated to load in a data value onto the first capacitor. After the data programming phase, the second capacitor may be configured to receive a lower voltage, which extends a threshold voltage sampling time for the pixel. Configured and operated in this way, the temperature luminance sensitivity of the display can be reduced.

Abstract: A display may include an array of pixels, where each pixel in the array includes an organic light-emitting diode coupled to a drive transistor and other associated thin-film transistors. The array may be grouped into column pairs, where each column pair includes a first pixel column and a second pixel column that is mirrored with respect to the first pixel column. The drive transistors within each column pair may be formed towards the center of that column pair, whereas the data lines associated with that column pair may be formed along the outer peripheral edges of that column pair. Configured in this way, parasitic coupling between the data lines and any sensitive/floating nodes of the drive transistor may be substantially reduced, which mitigates pixel column crosstalk and ensures luminance uniformity across the display.
