1. A pixel circuit, comprising:
a drive circuit;
a data write circuit, connected between a data line and the drive circuit and configured to transmit a data voltage of the data line to the drive circuit during a data writing stage; and
a light-emitting device, wherein a second electrode of the light-emitting device is connected to the data line, and during a light emission stage, a second power voltage is transmitted to the second electrode of the light-emitting device through the data line;
wherein the drive circuit is connected between a power line and a first electrode of the light-emitting device and is configured to generate a drive current according to a voltage of a control terminal of the drive circuit during the light emission stage to drive the light-emitting device to emit light, wherein the power line is configured to transmit a first power voltage.
