Patent ID: 8681141

Claim:
A display system comprising: a display for displaying an image; a support to support the display; a detector coupled to the support to detect an approach of an object; a controller to control the power source based on one or more predetermined commands corresponding to one or more detection signals from the detector; a light emitter to emit a plurality of light emitting patterns, wherein the light emitter is provided on the support of the display; and a power source to provide power to at least one of the display, the detector, the controller or the light emitter, wherein the light emitter emits a different one of the light emitting patterns for different operating modes of the display, the modes of the display including: (a) a start mode when a power-on-mode command is inputted based on a first detection signal from the detector, (b) a normal mode when the power-on command is inputted and at least one of a synchronization signal or a color signal is inputted, (c) a power-saving mode when the power-on command is inputted and at least one of the synchronization signal or the color signal is not inputted, (d) a power-off mode when a power-off command is inputted based on a second detection signal from the detector, and (e) an error informing mode when a count value of a low logic interval of a third detection signal from the detector is greater than a first and second reference values, wherein the error informing mode is generated when an error detection is recognized for one of the power-on or power-off commands.
