Abstract
A pixel circuit includes a data writing sub-circuit inputs a signal input via a second signal terminal to a compensating sub-circuit and a driving sub-circuit under control of a signal from a first signal terminal, the compensating sub-circuit compensates a threshold voltage of the driving sub-circuit according to a signal output from the data writing sub-circuit under control of a signal from a third signal terminal, a light-emitting control sub-circuit inputs a signal from a first voltage terminal to the driving sub-circuit and the compensating sub-circuit under control of a signal from a fourth signal terminal, the driving sub-circuit configured to generate and input a driving current to a light-emitting sub-circuit according to a signal output from the light-emitting control sub-circuit and a signal output from the data writing sub-circuit, and the light-emitting sub-circuit configured to emit light according to the driving current under control of a second voltage terminal.
