Abstract: The present disclosure relates to a display apparatus and a method of controlling the display apparatus. The display apparatus comprises a first signal transceiver; a second signal transceiver installed at a position different from the first signal transceiver; a processor configured to determine a position in a two-dimensional space or a three-dimensional space of at least one detection object using the first signal transceiver and the second signal transceiver, and to generate a control signal corresponding to the position of the at least one detection object; and a display configured to operate according to the control signal. The processor is configured to control at least one of the first signal transceiver and the second signal transceiver to radiate a first electromagnetic wave of a first frequency, when the at least one of the first signal transceiver and the second signal transceiver receives a first reflected wave reflected from the at least one detection object, to control the first signal transceiver to radiate a second electromagnetic wave of a second frequency higher than the first frequency, and to control the second signal transceiver to radiate a third electromagnetic wave of a third frequency higher than the first frequency, and to determine the position of the at least one detection object based on a second reflected wave corresponding to the second electromagnetic wave and a third reflected wave corresponding to the third electromagnetic wave.
