    Abstract: A display system configured to quickly restore a screen display without re-starting, even though the power supply from the outside is temporarily interrupted. The display system includes a display to display a screen based on image information to be displayed, and a power supply configured to support the display module and supply power to the display module in a wireless manner. The display is configured to, when the display is spaced apart from the power supply by a predetermined distance or more, selectively operate in one of a power saving mode for lowering luminance of at least a portion of the screen and an ultra-power saving mode for turning OFF at least a portion of the screen while maintaining a turned-on state of the display.
