There is provided a pixel circuit, a display panel, a drive method. The pixel circuit comprises a switch sub-circuit, a storage sub-circuit, a drive sub-circuit. The switch sub-circuit is connected to a gate line, a data line, the storage sub-circuit, and configured to transmit a signal on the data line to the storage sub-circuit under control of a signal on the gate line. The storage sub-circuit is connected to a first voltage terminal, a second voltage terminal, and the drive sub-circuit, and configured to transmit a signal of the first voltage terminal or the second voltage terminal to the drive sub-circuit under control of the switch sub-circuit. The drive sub-circuit is connected to the first voltage terminal, the second voltage terminal, a pixel electrode, and configured to transmit the signal of the first voltage terminal or the second voltage terminal to the pixel electrode under control of the storage sub-circuit.
