Abstract
A display panel, a method for driving a display panel, and a display device are provided. A first scanning driving unit is electrically connected to first scanning control terminals of first and second pixel driving circuits. A working cycle of the pixel driving circuit includes a data writing phase. The data writing phase of the first pixel driving circuit is prior to the data writing phase of the second pixel driving circuit in a display duration of one frame of an image. When the first pixel driving circuit and the second pixel driving circuit receive a same data voltage, a potential Vof the first node in the first pixel driving circuit after the data writing phase of the first pixel driving circuit is greater than a potential Vof the first node in the second pixel driving circuit after the data writing phase of the second pixel driving circuit.
