Claim Text:
1. A pixel circuit comprising: a first pixel sub-circuit and a second pixel sub-circuit different from the first pixel sub-circuit, as well as an initialization module and a data voltage writing module connected to the first pixel sub-circuit and the second pixel sub-circuit, wherein the initialization module is connected to a reset signal terminal and a low potential terminal, and is configured to initialize the first pixel sub-circuit and the second pixel sub-circuit under the control of a reset signal inputted from the reset signal terminal; the data voltage writing module is connected to a data voltage terminal and a gate signal terminal, and is configured to, under the control of a signal inputted from the gate signal terminal, firstly write a first data voltage to the first pixel sub-circuit and the second pixel sub-circuit and then to write a second data voltage to the first pixel sub-circuit; wherein after the first data voltage is written to the first pixel sub-circuit and the second pixel sub-circuit, the second pixel sub-circuit performs compensation on a driving module of the second pixel sub-circuit; the data voltage writing module writes the second data voltage to the first pixel sub-circuit only after the compensation on the driving module of the second pixel sub-circuit is performed; after the second data voltage is written to the first pixel sub-circuit, the first pixel sub-circuit performs compensation on a driving module of the first pixel sub-circuit; wherein after the first data voltage is written into the first pixel sub-circuit and the second data voltage is written into the second pixel sub-circuit, the first pixel sub-circuit and the second pixel sub-circuit emit light concurrently.
