Abstract
Exemplary embodiments of the application disclose pixel circuits and driving methods thereof, display devices. A pixel circuit includes a first through seventh thin film transistors, a light-emitting diode, and a storage capacitance. The pixel circuit provided by exemplary embodiments of the application can compensate a power voltage during a light-emitting stage of the light-emitting diode, so that the current flowing through the LED is related to a data voltage and a reference voltage input into the pixel circuit, and is independent of the power voltage, thereby effectively avoiding the problem of the display unevenness of the display device, due to the difference in the current flowing into the LED caused by the power voltage drop.
