Driving apparatus, driving method and display apparatus

A driving apparatus for driving a light-emitting element, comprising:

• a source driving circuit configured to generate a row scanning signal required for driving the light-emitting element and a data signal, wherein the data signal is written into a driving control circuit for the light-emitting element when the row scanning signal is valid;
• the driving control circuit configured to write a parameter of a driving element for the light-emitting element while writing the data signal when the row scanning signal is valid, wherein the driving control circuit is further configured to receive a level control signal and provide a driving voltage to the driving element according to the data signal, the parameter of the driving element and the level control signal in a light emission phase of the light-emitting element;
• and
• the driving element configured to convert the driving voltage provided by the driving control circuit into a driving current, and provide the driving current to the light-emitting element, so that the light-emitting element emits light under the driving of the driving current provided by the driving element;
• wherein the level control signal is configured to comprise a high level and a low level, one of which causes the driving voltage not to be sufficient enough to drive the driving element, and the other of which causes the driving control circuit to provide the driving voltage to the driving element according to the data signal and the parameter of the driving element to cause the light-emitting element to emit light,
• wherein the driving apparatus further comprises a voltage selector configured to receive a selection signal, select a power supply signal at one of a high level and a low level according to the selection signal, and output the power supply signal selected to the driving control circuit as the level control signal, and
• wherein a duty ratio between the high level and the low level of the level control signal is adjustable.
