1. A pixel circuit comprising:
a light-emitting element;
a capacitor structure;
a driving transistor;
a first switching element configured to connect a data line for providing a data signal to a first terminal of the capacitor structure in response to a first scan signal;
a second switching element configured to connect a first terminal of the driving transistor to a control terminal of the driving transistor and a second terminal of the capacitor structure respectively in response to a second scan signal;
a third switching element configured to connect a second terminal of the driving transistor to a first terminal of the light-emitting element in response to a third scan signal;
a fourth switching element configured to connect a first power signal terminal to the first terminal of the driving transistor in response to a fourth scan signal; and
a fifth switching element configured to connect the second terminal of the driving transistor and a second terminal of the light-emitting element in response to a fifth scan signal;
wherein the first terminal of the light-emitting element is connected to a ground terminal.
