Electronic device and its driving method with an adjustable driving voltage

A method for driving an electronic device, the electronic device comprising a display panel, a gate driving circuit and a control unit, the display panel comprising a display scan line and a dummy scan line, the gate driving circuit comprising a first output unit and a second output unit, the control unit being electrically connected to the gate driving circuit, the method comprising:

• the first output unit providing a display scan signal to the display scan line, the second output unit providing a test scan signal to the dummy scan line;
• the control unit receiving the test scan signal;
• the control unit updating a driving voltage according to the test scan signal to generate an updated driving voltage;
• and
• the control unit driving the gate driving circuit according to the updated driving voltage.
