Title: PIXEL CIRCUIT, DRIVING METHOD, DISPLAY PANEL, AND DISPLAY DEVICE
Abstract:
A pixel circuit, a driving method, and a display device. The pixel circuit comprises: at least two pixel subcircuits (10), a data line (Data), a first scan line (Scan1), a second scan line (Scan2), a third scan line (Scan3), and a light emission control line (EM). The pixel subcircuits (10) comprise correspondingly: a light emission control subcircuit (1), a node resetting subcircuit (2), a drive control subcircuit (4), a write subcircuit (3), and a light-emitting component (6). For each pixel subcircuit (10): the light emission control subcircuit (1) is configured, under the control of a light emission control end, to provide a signal of a first voltage signal end to a first node (a); the node resetting subcircuit (2) is configured, under the control of a first scan signal end, to connect the first node (a) to a second node (b); the write subcircuit (3) is configured, under the control of a second scan signal end, to write a data signal and a threshold voltage outputted by a data signal end into the second node (b); and the drive control subcircuit (4) is configured, under the control of the second node (b), to drive the light-emitting component (6) to emit a light.
