The digital signage system includes a panel configured to display an image, a plurality of light emitting diode (LED) driver modules configured to provide to the panel, a display device including at least one power supply unit configured to supply power to the panel and the plurality of LED driver modules, and a system controller configured to control the display device. The system controller includes a display configured to display a luminance setting screen for controlling luminance of the image and a controller configured to change a settable maximum luminance value according to the number of power supply units when the luminance setting screen is displayed."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Digital signage system and operating method therefor","description":"Disclosed herein are a digital signage system for limiting a luminance range settable by a user according to the number of power supply units (PSUs) and a method of operating the same.
