1. A display pixel, comprising:

  • an organic light-emitting diode;

    a plurality of transistors one of which is a drive transistor that supplies a current to the organic light-emitting diode and that has a threshold voltage; and

    a capacitor coupled to the drive transistor and the organic light-emitting diode, wherein the transistors are controlled using first, second, and third phases in each of a plurality of image frames, wherein the first phase is a reset and data writing phase in which data is loaded into the display pixel, the second phase is a threshold voltage compensation phase in which an initialization voltage is placed on a gate of the drive transistor, and the third phase is an emission phase in which the drive transistor supplies current to the organic light-emitting diode that is independent of the threshold voltage and that is responsive to the data that has been loaded into the display pixel.
