Pixel driving circuit, driving substrate and display device

The invention provides a pixel driving circuit, a driving substrate and a display device. The method comprises the following steps: a field effect transistor comprising a grid electrode and a source electrode; the drift correction component is electrically connected between the grid electrode and the source electrode; the drift correction assembly is configured to generate a gate-source voltage difference between the gate electrode and the source electrode so as to correct the drift of the threshold voltage of the field effect transistor. According to the scheme, the gate-source voltage difference equal to the conduction voltage difference can be maintained between the gate and the source, so that the threshold voltage is maintained to be positively biased to a certain extent, and the phenomenon that the threshold voltage is too negatively biased is avoided. 本申请提供一种像素驱动电路、驱动基板及显示装置；所述方法包括：场效应晶体管，包括栅极和源极；漂移修正组件，电连接于所述栅极和所述源极之间；所述漂移修正组件被配置为，使所述栅极到所述源极之间产生栅源电压差，以修正所述场效应晶体管的阈值电压的漂移。本方案可以在栅极和源极之间维持在等同于导通压差的栅源电压差，从
