Abstract
Disclosed are a pixel circuit, a method for driving the same, a display panel, a display device, and the pixel circuit which includes a driving transistor structured with double-gates, a first switch transistor, a second switch transistor, a third switch transistor, a fourth switch transistor, a first capacitor, a second capacitor, and a light-emitting element; and the respective transistors and capacitors above cooperate with each other to compensate for threshold voltage of the driving transistor, so that driving current to drive the light-emitting element to emit light is only dependent upon voltage of a data signal, the light-emitting element is avoided from being affected by the threshold voltage of the driver control module, and when the same data signal is applied to different pixel elements, an image at the same brightness can be displayed.
