Abstract: A display device includes an interface, a power supply, a switch arrangement, and a display. The interface is driven by driving power and receives image data from an external source. The power supply generates first and second power based on a first input power in a first mode and delivers the driving power to the interface in the first mode. The switch arrangement forms a first delivery path to deliver the first power from the power supply to the interface in the first mode The display receives the second power from the power supply when driven in the first mode and receives the image data from the interface. The switch arrangement forms a second delivery path to deliver second input power to the power supply in a second mode when the interface receives the second input power from the external source in the second mode.
