Abstract
A pixel circuit, a display panel, a display device, and a driving method are provided. The pixel circuit includes: a light-emitting device; a drive transistor configured to generate driving current for driving light-emitting device to emit light according to data voltage; a data writing circuit configured to provide, in response to scan signal terminal signal, data voltage of a data signal terminal to a first node; a threshold compensation circuit configured to write threshold voltage of drive transistor to a second node; a first coupling control circuit between the first node and the gate of the drive transistor and configured to stabilize voltages of first node and the gate of the drive transistor; a second coupling control circuit between the first and second nodes, and configured to stabilize voltages of first and second nodes and couple an amount of voltage variation of the first node to the second node.
