Display panel and display device

A method for driving a display panel, wherein the display panel comprises:

• a plurality of source driving chips;
• a power management circuit, comprising a first output terminal, the first output terminal being configured to provide a digital power signal to the source driving chips;
• and a plurality of switching units, respectively arranged corresponding to at least one of the source driving chips, the switching units being connected between the first output terminal and corresponding source driving chips, and at least part of the switching units being configured to be conductive, in response to different control signals, between the corresponding source driving chips and the first output terminal in different time periods, the method comprising:
• in a power-on reset stage of the source driving chip, inputting different control signals to control terminals of at least part of the switching units to turn on the switching units in different time periods.
