Abstract
A display device and an operating method of the display device are provided. The display device may include: a first transistor controlled by a first control signal to connect an input terminal to which an input voltage is applied and a first node; a second transistor controlled by a second control signal to connect a second node to which a power supply voltage is outputted and the first node; an overcharge recognition circuit configured to receive a first reference voltage, a feedback voltage, and a second reference voltage, to determine whether it is overcharged, and to output an overcharge recognition signal; and a discharge circuit configured to provide a first discharge path for discharging the power supply voltage based on an enable signal generated depending on the overcharge recognition signal.
