Abstract: A display apparatus includes a cabinet; a light emitting diode module provided in the cabinet; a communicator configured to receive an ambient atmospheric measurement value of the cabinet from an external device; a temperature sensor provided in the light emitting diode module; and a temperature controller configured to control a temperature of the light emitting diode module; and a controller configured to control the temperature controller so that the temperature of the light emitting diode module is greater than a dew point temperature when the measured temperature based on the output of the temperature sensor in a standby mode in a power saving state is equal to or lower than the dew point temperature based on the ambient atmospheric measurement value, and drives the light emitting diode module so that the temperature of the light emitting diode module is greater than the dew point temperature when the measured temperature is below the dew point temperature based on the ambient atmospheric measurement value when switching to an active mode in a normal power supply state.

Abstract: A display apparatus, a content management apparatus, a content management system, and a content management method for verifying correct reproduction of content are provided. The display apparatus may include: a receiver configured to receive a content image; a display configured to reproduce the content image and display, over the content image being reproduced, a content identification color for identifying the content image; a sensing device mounted on at least one side of the display; and a controller configured to generate reproduction confirmation data for verifying reproduction of the content image based on an output of the sensing device.
