Abstract: A pixel circuit, a method for controlling a pixel circuit, an array substrate, and a display panel are provided. Based on the structural improvement of the pixel circuit, when the light-emitting control signal is maintained at a high level, turning on a driving transistor by changing a Vgate signal from a high level to a low level, to complete a reset initialization of the driving transistor; and compensating a turn-on voltage of the driving transistor by changing a Vdata signal from a low level to a high level.
