The invention provides a pixel circuit, a driving method therefor, and an active matrix organic light-emitting display. A first scanning control signal line, a second scanning control signal line and a third scanning control signal line are respectively used for controlling the working state of a fourth thin film transistor, the working state of a fifth thin film transistor and the working state of a second thin film transistor. A light-emitting control signal line is used for controlling the working state of a first thin film transistor and the working state of a sixth thin film transistor, thereby enabling the current outputted by a third thin film transistor serving as a driving element to be unrelated with a threshold voltage of the third thin film transistor. Therefore, the active matrix organic light-emitting display employing the pixel circuit and the driving method can prevent the deviation of the threshold voltage of the thin film transistor from causing brightness unevenness, and improving the display quality of an image.
