Abstract:
The embodiments of the present application provide a pixel circuit, a method for driving the same, and a display apparatus. A driving sub-circuit in the pixel circuit includes a driving transistor and a first storage capacitor. The first storage capacitor has a first terminal electrically coupled to a gate of the driving transistor, and a second terminal coupled to a second electrode of the driving transistor. A writing sub-circuit is coupled to a scanning signal line, a data line, and the gate of the driving transistor, and is configured to write a data voltage into the driving transistor and maintain the driving transistor to be turned on. A reset sub-circuit is configured to supply an initial voltage to the light emitting sub-circuit so as to reset the light emitting sub-circuit. The driving transistor is further coupled to the light emitting sub-circuit to drive the light emitting sub-circuit to emit light.
