Abstract:
The application provides pixel driving method, pixel driving device and display apparatus. The method is used for driving light emission of light emitting element in duration of image frame in display panel, the duration of image frame including display driving period and stable display period which are consecutive. The method includes: receiving first data voltage for image display in display driving period of current image frame to generate driving current through driving transistor for driving light emission of the light emitting element; receiving second data voltage for detection and first reference voltage in stable display period of current image frame to detect threshold voltage of the driving transistor; adjusting first reference voltage to generate second reference voltage in display driving period of next image frame, generating driving current for driving light emission of the light emitting element based on second reference voltage.
