Abstract: The present disclosure provides a driving apparatus for driving a light-emitting element. By dividing a light emission phase of the light-emitting element into at least two sub-phases, i.e., adding a dual-level level control signal, wherein one level causes the light-emitting element to emit light normally and the other level causes the light-emitting element to be turned off or operate under an extremely small current. By adjusting a duty ratio of the dual-level level control signal, a driving current of the light-emitting element during light emission can be adjusted to realize accurate control of the driving current of the light-emitting element. The present disclosure further provides a driving method for the driving apparatus and a display apparatus including the driving apparatus.
