Abstract

A display device includes a power managing circuit which generates a display driving voltage, a display driving circuit which receives the display driving voltage, and a display panel to display an image. The power managing circuit includes a converting circuit which converts the input voltage into the display driving voltage, and outputs the display driving voltage through an output terminal, a load sensing circuit connected to the converting circuit to sense a load current of the output terminal and which outputs a sensing result signal, a resistance dividing circuit connected to a feedback terminal to receive a feedback voltage, and which controls a level of the feedback voltage in response to a feedback control signal, and a control circuit which controls an operation of the converting circuit by providing the feedback control signal to the resistance dividing circuit based on the sensing result signal.
