Disclosed is a display apparatus including: a wireless power receiver configured to wirelessly receive power from an external power source to supply power to the display apparatus; a display configured to display an image based on a received image signal; communication circuitry configured to communicate with the external module; information acquiring circuitry configured to acquire information about a distance between the display apparatus and a user; and a controller configured to determine consumption power of the display apparatus, to control the communication circuitry to provide information about the determined consumption power to the external module, and to reduce the consumption power of the display apparatus if it is determined based on the acquired information that the user is within a predetermined critical distance of the display apparatus. Thus electromagnetic waves harmful to a human body is controlled to reduce and/or eliminate an affect a user.
