Abstract
A pixel circuit includes a data writing and compensation sub-circuit, a driving sub-circuit, and a light-emitting control sub-circuit. The data writing and compensation sub-circuit is configured to transmit a data signal from a data voltage terminal to the driving sub-circuit under control of a first control signal terminal, and to compensate a threshold voltage of the driving sub-circuit under the control of the first control signal terminal. The light-emitting control sub-circuit is configured to transmit a first voltage signal from a first voltage terminal to the driving sub-circuit and the data writing and compensation sub-circuit under control of a second control signal terminal, and to transmit a second voltage signal from the second voltage terminal to the driving sub-circuit under the control of the second control signal terminal. The driving sub-circuit is configured to transmit a signal output from the light-emitting control sub-circuit to a light-emitting sub-circuit.
