Abstract
The present disclosure can provide a pixel circuit, a driving method thereof and a display device. By arranging a data write circuit, a driving control circuit, a light-emitting control circuit and a light-emitting device, the data write circuit provides a data signal of the data signal end for the driving control circuit in response to a signal of a first scanning signal end; the driving control circuit generates a driving current according to the data signal; and the light-emitting control circuit connects the driving control circuit with a cathode of the light-emitting device in response to a signal of a second scanning signal end, so that the driving current is input into the light-emitting device to control the light-emitting device to emit light. Besides, a voltage of the first power end is larger than that of the second power end.
