PIXEL CIRCUIT, DRIVING METHOD THEREFOR, LIGHT-EMITTING DISPLAY PANEL, AND DISPLAY DEVICE

摘要

A pixel circuit, a driving method therefor, an organic light-emitting display panel, and a display device. The pixel circuit comprises a display driving module (1) and a fingerprint recognition module (2). The display driving module (1) is connected to a first scan line (Scan1), a second scan line (Scan2), a control line (EM), a data line, a second signal source, a third signal source, and an anode of an organic light-emitting diode (OLED) and is used for allowing, under the control of a first scan signal, a second scan signal, and a control signal, a light emission driving signal of the organic light-emitting diode (OLED) and a threshold voltage of a driving transistor to be independent of each other; the fingerprint recognition module (2) is connected to the first scan line (Scan1), the second scan line (Scan2), a fourth signal source, and a signal reading line and is used for implementing, under the control of the first scan signal and the second scan signal, fingerprint recognition and touch detection functions.
