1. A pixel circuit, comprising:

  • a charge control module, a drive module, a reset control module, a light-emitting control module and a light emitting device;

    whereina control end of the charge control module is connected with a scan signal end, an input end thereof is connected with a data signal end, and an output end thereof is connected with the first input end of the reset control module;

    a control end of the reset control module is connected with a threshold voltage signal end, the second input end is connected with a reference signal end and an input end of the drive module, respectively, the first output end is connected with a control end of the drive module, and the second output end is connected with an output end of the drive module and an input end of the light-emitting control module, respectively;

    a control end of the light-emitting control module is connected with a light-emitting signal end, an output end thereof is connected with an input end of the light emitting device; and

    an output end of the light emitting device is connected with a low level signal end;

    in the reset and compensation phase, the charge control module makes the data signal end and the first input end of the reset control module switch on under the control of the scan signal end;

    the reset control module resets the control end and the output end of the drive module and compensates reference voltage under the control of the threshold voltage signal end and the reference signal end;

    in the data writing phase, the charge control module writes the data signal inputted by the data signal end to the first input end of the reset control module under the control of the scan signal end;

    in the light-emitting phase, the light-emitting control module makes the output end of the drive module and the input end of the light emitting device switch on to drive the light emitting device to emit light under the control of the light-emitting signal end.
