An AMOLED pixel circuit. A third thin film transistor (T3) is arranged between a first and a second thin film transistor (T1, T2). The opening and closing of the third thin film transistor (T3) are controlled by inputting a control signal through a control line (Control), so that the AMOLED pixel circuit is controlled to carry out driving current measurement through a current measurement circuit (1) and carry out signal voltage correction through a signal voltage driving circuit (2) or carry out normal displaying. Therefore, the driving current entering an organic light-emitting diode (D) in each pixel can be corrected, the problems of unstable luminous brightness and non-uniform displaying that are caused by change of the characteristic of the organic light-emitting diode (D) along with the time and the temperature are solved, and the display effect is improved. |
