Abstract: The present disclosure relates to a method and an apparatus for controlling a drive current of a display panel, an electronic device, and a storage medium. A standard drive current of the display panel is calculated based on the power function of the display panel. An actual drive current is detected in a working process of the display panel, and it is determined whether the actual drive current exceeds the standard by comparing the actual drive current with the standard drive current. The actual drive current is regulated if the actual drive current exceeds the standard.
