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.

Abstract: The present disclosure relates to a pixel circuit, a driving method thereof and related devices. The pixel circuit comprises: a reset compensation module, a data writing module, a storage module and a driving transistor. With the cooperation of each module, the pixel circuit can compensate shift of a threshold voltage for a driving transistor by storing the threshold voltage for the driving transistor in the storage module. Therefore, when the source of the driving transistor in the pixel circuit is connected with a light emitting device for driving it to emit light for display, the driving current of the driving transistor for driving the light emitting device to emit light will be only associated with the voltage of the data signal, but not the threshold voltage for the driving transistor. In this way, influence of the threshold voltage of the driving transistor on the light emitting device will be avoided.
