Claim:
1. A pixel circuit, comprising a first storage capacitor, a driving transistor and an organic light-emitting diode (OLED), a gate electrode of the driving transistor being connected to a second end of the first storage capacitor, wherein the pixel circuit further comprises: a display driving module, connected to a first scanning line, a second scanning line, a control line, a data line, a first signal source and a second signal source, respectively, and configured to, within a time period and under the control of a first scanning signal from the first scanning line, a second scanning signal from the second scanning line and a control signal from the control line, compensate for a threshold voltage of the driving transistor with a data signal from the data line and a second signal from the second signal source, so that a light-emitting driving signal for the OLED is irrelevant to the threshold voltage of the driving transistor at a third stage of the time period; and a capacitive touch detection module, connected to the first scanning line, the control line, the data line, a third signal source and a signal reading line, respectively, and configured to, within the time period and under the control of the first scanning signal and the control signal, detect a touch signal from a touch screen.
