Abstract
A pixel circuit and a method therefor, and an organic light-emitting display. The pixel circuit initializes an anode of an organic light-emitting diode (OLED) by means of a first thin-film transistor, a second thin-film transistor and a seventh thin-film transistor, and initializes a gate and a drain of a sixth thin-film transistor serving as a driving element by means of the first thin-film transistor, a third thin-film transistor and the seventh thin-film transistor so that the service life of the OLED and the service life of the sixth thin-film transistor are prolonged. The current output by the sixth thin-film transistor serving as a driving element is irrelevant to the threshold voltage of the sixth thin-film transistor and the impedance of the power wiring, and thus uneven brightness caused by deviation of the threshold voltage of the thin-film transistor and different impedances of the power wiring can be avoided. Therefore, for the organic light-emitting display that adopts the pixel circuit and the driving method therefor, the service life is prolonged and the display quality is improved.
