The invention discloses a pixel circuit, a display panel and a driving method, for improving the problem that, for the organic light emitted diode (OLED) display panel in the prior art, the light-emitting brightness of light-emitting devices at different positions is different, resulting in nonuniformity of the light emitting brightness of the whole OLED display panel. The pixel circuit comprisesa first switch transistor and a second switch transistor; in a first stage, the first switch transistor is configured to connect a data signal end with a first node in response to a first compensationsignal of a compensation signal end, and the second switch transistor is configured to connect the first node with a second node in response to a first grid signal of a grid signal end; in a second stage, the second switch transistor is configured to disconnect the first node and the second node in response to a second grid signal of the grid signal end; and in a fourth stage, the second switch transistor is configured to connect the first node and the second node.
