Abstract:
1. A pixel circuit comprising a load controlling module, a load module, a gray scale selection module, a driving module and a light-emitting device, wherein: the load controlling module is connected with a first scan signal line and a data signal line, and is used for outputting an analog data signal through a first node and a second node under a control of a first scan signal; the load module is connected with a first power supply terminal, the driving module, the first node and the second node, respectively, and is used for storing the analog data signal under an action of a first power supply and providing the driving module with the analog data signal, under controls of signals from the first node and the second node; the gray scale selection module is connected with a second scan signal line and the data signal line, and is used for transmitting a digital data signal to a third node located in the gray scale selection module under a control of a second scan signal; the driving module is used for driving the light-emitting device under controls of the signals from the second node and the third node; and a first terminal of the light-emitting device is connected with a second power supply terminal, a second terminal thereof is connected with the driving module, and the light-emitting device emits light under actions of the second power supply and the driving module.
