Abstract
A pixel circuit is disclosed, comprising: a driving module, an energy storage module, an electroluminescence module, a data voltage write module and a threshold compensation module, the threshold compensation module being connected with a compensation voltage input end, a first end of the energy storage module and at least one control signal input end, adapted to compensate the voltage of the first end of the energy storage module as a sum of the startup threshold of the driving module and the compensation voltage accessed by the compensation voltage input end in response to the control signal accessed by the connected control signal input end.
