Abstract: An image display device includes an external device interface unit configured to connect the image display device with an external device; a display unit configured to display an image received from the external device; a user input interface unit configured to receive an input signal and to send a control signal corresponding to the input signal to a relay device acting a communication relay between the image display device and the external device; and a controller configured to in response to the image display device being powered on, check whether or not a connection log of the image display device includes a previous connection between the image display device and the relay device, scan for an advertisement packet from the relay device at a first scan interval when the connection log does not include the previous connection between the image display device and the relay device, and scan for the advertisement packet from the relay device at a second scan interval having a longer time duration than the first scan interval when the connection log includes the previous connection between the image display device and the relay device.

Abstract: The present invention relates to a display device, and to a method for controlling the same. To this end, the display device of the present invention may comprise a communication unit and at least one processor. The communication unit may receive a first code for a first key input from a remote control device. The at least one processor transmits a command for the received first code to an infrared blaster through the communication unit, and based on receiving a control signal for the first key from a peripheral device connected to be operable with the display device, the processor may be configured to operate the display device.
