Abstract: An electronic device includes a display panel, a gate driving circuit and a control unit. The display panel includes a display scan line and a dummy scan line. The gate driving circuit includes a first output unit for providing a display scan signal to the display scan line, and a second output unit for providing a test scan signal to the dummy scan line. The control unit is electrically connected to the gate driving circuit for receiving the test scan signal, updating a driving voltage according to the test scan signal, and driving the gate driving circuit according to the updated driving voltage.
