Abstract
This display device is provided with: a gate driver that drives a display panel; and a control circuit that controls driving of the gate driver. The control circuit is provided with: a Voltage supply circuit that supplies a Voltage to the gate driver; and a current detection circuit that detects a current to be supplied to the gate driver. The display device reduces, in stages, the voltage to be supplied to the gate driver, and detects the current to be supplied to the gate driver, and in the cases where the detected current is equal to or lower than a predetermined value or a current increase is detected, the display device acquires a first voltage being supplied to the gate driver, and sets a second voltage as a drive voltage for driving the gate driver, said second voltage being obtained by adding a predetermined voltage to the acquired first voltage.
