Claim:
1. A pixel circuit, comprising: a drive transistor, a drive control module, at least two split light emitting control modules and light emitting devices connected with output terminals of the split light emitting control modules in one-to-one correspondence respectively; wherein an input terminal of the drive control module is used for receiving a drive control signal, a first output terminal of the drive control module is connected with a gate of the drive transistor, a second output terminal of the drive control module is connected with a source of the drive transistor; the drive control module is used for controlling the drive transistor to output a driving total current signal under the control of the drive control signal; a first input terminal of each of the split light emitting control modules is connected with a drain of the drive transistor, a second input terminal thereof is used for receiving a corresponding split control signal, a third input terminal thereof is used for receiving a corresponding light emitting control signal, an output terminal thereof is connected with one end of a corresponding light emitting device; the other end of the light emitting device is connected with a first reference voltage source; each of the split light emitting control modules is used for splitting the driving total current signal outputted by the drain of the drive transistor according to the corresponding split control signal under the control of the corresponding light emitting control signal, forming a driving split current signal to which the corresponding split control signal corresponds, and providing the formed driving split current signal to the corresponding light emitting device.
