Abstract: The present application discloses a display-driving method and a display apparatus. The method includes performing an internal compensation to a driving transistor within a display-driving circuit for light-emission in a display-driving time per scan cycle and additionally performing an external compensation via an external-control-sub-circuit in a blanking time between two scan cycles. The method includes using the compensation-control sub-circuit to input a reference voltage to make a driving transistor in conduction state in s start period of the blanking time and increase a voltage level on a sense line associated with the display-driving circuit in an external-compensation period. The method further includes reading the voltage on the sense line at an end of the external-compensation period as a compensation voltage. Furthermore, the method includes using the external-control sub-circuit to correct a data voltage to be supplied to a data line based on the compensation voltage.
