Abstract
The present invention provides a pixel circuit and a driving method thereof, as well as a display device. The pixel circuit comprises a drive transistor and a first energy storage element, a source of the drive transistor being connected with a first end of the first energy storage element. The pixel circuit further comprises a driving module, and has a reset voltage input terminal, a data voltage input terminal, a working voltage input terminal and a plurality of control signal input terminals. The pixel circuit provided by the present invention can prevent the driving current flowing through the electroluminescent unit from being influenced by the turn-on threshold value of the corresponding drive transistor, thereby solving the problem of non-uniform display brightness caused by drift of the turn-on threshold value of the drive transistor thoroughly.
