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.
