1. A driving method for a display device, comprising steps of:
providing a display device comprising a plurality of sub-pixels, wherein each sub-pixel comprises an OLED light-emitting element, a light-emitting control transistor configured to transmit a driving current to the OLED light-emitting element, and a reset transistor coupled to an anode of the OLED light-emitting element;
inputting a plurality of periodic cut-off signals to the light-emitting control transistor;
determining an effective light-emitting phase of each frame period for the sub-pixel; and
during the effective light-emitting phase of each frame period for the sub-pixel, inputting a reset signal to the reset transistor at the same timing as one or more of the plurality of cut-off signals.
