Abstract
The present disclosure provides a display apparatus, a pixel circuit and a method of driving a pixel circuit. In one or more embodiments, the pixel circuit includes a driving transistor, a data signal module and a bias signal module. A first electrode of the driving transistor is connected with a first power signal terminal, a second electrode of the driving transistor is connected with a first terminal of a light emitting element, and the driving transistor includes a first control electrode and a second control electrode. The data signal module is connected with the driving transistor, a data writing signal terminal and a data signal terminal. The bias signal module is connected with the driving transistor, a bias writing signal terminal and a bias signal terminal, and is configured to adjust a threshold voltage of the driving transistor under control of the bias writing signal terminal and the bias signal terminal.
