摘要： Embodiments of the present disclosure provide a method and a device for detecting a threshold voltage drift of a transistor in a pixel circuit, which are used for detecting the threshold voltage drift of the transistor to be detected in the pixel circuit. The transistor to be detected is at least one of the driving transistor and the detection transistor. The detection method comprises: inputting, during an inputting stage, a first turning-on voltage to the second scanning terminal, so as to turn on the detection transistor, enabling writing a first voltage into the second node through the detection signal terminal; inputting, during a detection stage, a first turning-off voltage to the second scanning terminal, so as to turn off the detection transistor, thereby detecting an actual voltage at the second node; and determining a state of the threshold voltage drift of the transistor to be detected according to the actual voltage and the first voltage.
