摘要： A pixel circuit, a driving method, and a display panel. The pixel circuit includes a driving module, a data write module, a first compensation module, a second compensation module, a light-emitting module, a storage module, and a coupling module. The data write module is configured to write a voltage related to a data voltage to a control terminal of the driving module. The driving module is configured to provide a drive signal for the light-emitting module according to the voltage of the control terminal to drive the light-emitting module to emit light. A first terminal of the second compensation module is connected to the control terminal of the driving module, a second terminal of the second compensation module is connected to a first terminal of the first compensation module, and a second terminal of the first compensation module is connected to a first terminal of the driving module.

摘要： A pixel circuit, a driving method thereof, and a display panel. The pixel circuit includes a drive module, a data write module, an auxiliary module, a compensation module, a storage module, a coupling module, and a light-emitting module. The data write module is configured to write a data-voltage-related voltage to a control terminal of the drive module through the auxiliary module . The compensation module is connected between a first terminal of the drive module and the control terminal of the drive module and is configured to compensate for the threshold voltage of the drive module. The coupling module is connected to the compensation module and is configured to adjust the voltage at the control terminal of the drive module according to a received jump voltage by using the compensation module. The storage module is connected to the control terminal of the drive module.
