An OLED pixel circuit includes a data storage and threshold compensation module, a switch module, a driving module, and a light-emitting module. The data storage and threshold compensation module is connected to the driving module, the switch module, a scanning signal line, and a data signal line, respectively, and is used for inputting a data signal on the data signal line to the driving module and compensating a threshold voltage of the driving module according to a scanning signal of the scanning signal line. The switch module is connected to the driving module, the light-emitting module, and a light emission control signal line, respectively, and is used for inputting the data signal provided by the threshold-compensated driving module to the light-emitting module according to a control signal of the light emission control signal line, so that the light-emitting module is driven to emit light. |
