The present disclosure relates to a display system and a method of operating the display system for enabling display to be continued even if any of a plurality of power supply devices for normal luminance fails in a case where a power supply device for a high-luminance direct-view light emitting diode (LED) display is implemented by the plurality of power supply devices for normal luminance. A plurality of normal-luminance power supplies that supplies power necessary for driving a driver group that drives light emitting diodes (LEDs) arranged in an array on the basis of a video signal in a normal-luminance mode, and a power supply switch that switches on/off of power supply from the plurality of normal-luminance power supplies to the driver group are provided, and when an abnormality is detected in the power supply, the power supply switch is turned off, and the LEDs are switched from a high-luminance mode to the normal luminance mode and are driven, and then the power supply switch is controlled to be turned on. The present disclosure can be applied to an LED display device.
