Abstract
A pixel circuit unit, a driving method thereof, a display panel and a display device are disclosed. The pixel circuit unit includes a plurality of pixel drive circuits and a voltage control circuit including a first terminal and a second terminal; the first terminal is connected with a first voltage terminal to receive a first supply voltage provided by the first voltage terminal; each pixel drive circuit includes a light-emitting drive circuit including a supply voltage receiving terminal and a control terminal; the supply voltage receiving terminal is electrically connected with the second terminal, so as to allow the supply voltage receiving terminal to be capable of receiving the first supply voltage; and the voltage control circuit is configured to be disconnected in a data voltage writing stage, so that the supply voltage receiving terminal does not receive the first supply voltage in the data voltage writing stage.
