Abstract
Provided are a pixel circuit, a driving method and a display apparatus, including: a light emitting device; a driving transistor, configured to produce a current for driving the light emitting device to emit light according to a data voltage; a voltage control circuit, coupled to the driving transistor, wherein the voltage control circuit is configured to reset the driving transistor (M0) and input the data voltage in response to a loaded signal; and a light emitting control circuit, coupled to the driving transistor and the light emitting device, wherein the light emitting control circuit is configured to provide the current produced by the driving transistor to the light emitting device; wherein a frequency of resetting the driving transistor is not less than a frequency of inputting the data voltage.
