Display apparatus

A display apparatus comprising:

• a case;
• a display inside the case;
• a heat exchanger disposed on a rear surface of the case to perform heat exchange between an outside and an inside of the case;
• a first temperature sensing unit to sense a first temperature of a first space;
• a second temperature sensing unit to sense a second temperature of a second space;
• a third temperature sensing unit to sense a third temperature of the outside;
• a controller to control an air flow to be formed in at least one of the first space, the second space, or the outside, based on temperature information obtained from the first temperature sensing unit, the second temperature sensing unit, and the third temperature sensing unit;
• a first fan driving unit to drive at least one fan module disposed in the first space;
• a second fan driving unit to drive at least one fan module disposed in the second space;
• and
• a third fan driving unit to drive at least one fan module disposed at the outside,
• wherein the first space and the second space separated from each other are formed on a front surface and a rear surface of the display, respectively, and heat exchange is performed between the first space and the second space,
• wherein heat exchange with the second space and the outside is performed through the heat exchanger,
• wherein heat exchange is performed between the first space and the second space based on a first air flow in the first space and a second air flow in the second space,
• wherein the first air flow and the second air flow are separated from each other,
• wherein the display includes a panel and a circuit unit to output an electric signal to the panel, and
• wherein when the second temperature is highest and the third temperature is lowest among the first to third temperatures, the controller is configured to:
• not operate the first fan driver and to operate the second fan driver and the third fan driver;
• or
• operate only the second fan driver.
