Driving circuit of display panel, driving method thereof, and display panel

A driving circuit of a display panel, comprising:

• a turn-on voltage adjusting circuit, the turn-on voltage adjusting circuit comprising:
• a control subcircuit;
• and
• a switching and voltage division subcircuit;
• the switching and voltage division sub circuit comprising:
• a switching subcircuit;
• and
• a basic voltage division subcircuit;
• wherein the switching subcircuit includes a control terminal, a first input terminal, a second input terminal and an output terminal;
• the control terminal of the switching subcircuit is configured to input a control signal of a corresponding resolution, the first input terminal thereof is electrically connected with an output terminal of the control subcircuit, the second input terminal is configured to access a ground power supply signal, and the output terminal thereof is electrically connected with a voltage division feedback node;
• and
• the switching subcircuit is configured to perform voltage division of a signal outputted by the output terminal of the control subcircuit to form a voltage division feedback signal of the corresponding resolution under control of the control signal and output the voltage division feedback signal to the voltage division feedback node;
• and
• wherein the control subcircuit includes a first input terminal, a second input terminal and the output terminal, the first input terminal of the control subcircuit is electrically connected with the voltage division feedback node, the second input terminal thereof is configured to input an initial level signal, and the output terminal thereof is electrically connected with the first input terminal of the switching and voltage division subcircuit and is configured to output an turn-on voltage signal of the corresponding resolution.
