Abstract: A shift register unit, a gate drive circuit, a display panel and a display device are disclosed. The shift register unit combines a light emission signal output module with a scanning signal output module, i.e. integrating a light emission shift register unit and a scanning shift register unit into a circuit, thereby reducing the number of clock signals as required. The light emission signal output module and the scanning signal output module may be synchronously driven. The light emission signal output module continuously outputs a first reference signal or a second reference signal by controlling potentials of a first and fifth node. The scanning signal output module continuously outputs the second reference signal or a second clock signal by controlling potentials of a third and fourth node, thereby generating a light emission signal having multiple pulse widths, i.e. effecting duty ratio control to the light emission signal.

Abstract: Disclosed are a pixel Circuit, a driving method thereof, and a display apparatus. The pixel circuit comprises a driving transistor, a capacitor connected between the source and the gate of the driving transistor, a light-emitting element, a light-emitting control module, a data writing module and a compensating module. By cooperation among the various modules, the drift of the threshold voltage of the driving transistor can be compensated. Accordingly, the driving current which is provided by the driving transistor to drive the light-emitting element to emit light only relates to the voltage of the data signal and the reference signal, while does not relate to the threshold voltage of the driving transistor and the first reference voltage source, and thus the effect on the current flowing through the light-emitting element raised due to the threshold voltage and due to the IR drop can be avoided. The operating current which drives the light-emitting element to emit lights can remain uniform, thereby improving the uniformity of the image luminance of the whole display area of the display apparatus.
