Pixel circuit, display panel and display device

The invention discloses a pixel circuit, a display panel and a display device. The pixel circuit comprises a driving transistor, a compensation transistor and a pre-charging transistor, the pre-charging transistor is used for increasing the voltage of a first node; the first node is an intersection point of the driving transistor and the compensation transistor; the compensation transistor is used for providing a data signal for the driving transistor based on the boosted voltage of the first node; the driving transistor is used for providing driving current for the light-emitting element. According to the embodiment of the invention, the first node can be pre-charged, so that the pixel circuit can improve the charging efficiency and accelerate the charging process, and the problem that the actual brightness of a light-emitting element is relatively low due to insufficient charging of the pixel circuit is solved. 本申请公开了一种像素电路、显示面板及显示装置。像素电路包括：驱动晶体管、补偿晶体管和预充电晶体管；所述预充电晶体管用于提升第一节点的电压；所述第一节点为所述驱动晶体管与所述补偿晶体管的交点；所述
