1. An image display device comprising:
a memory storing at least one instruction;
a wireless communicator configured to communicate with an external control device controlling the image display device; and
a processor, wherein the processor by executing the at least one instruction stored in the memory is configured to:
obtain device identification information corresponding to an external device connected to the image display device;
control the wireless communicator to transmit, to the external control device, search data for the external control device to perform a discovering process for discovering the external device based on the device identification information; and
based on the external device being discovered by the external control device using the search data, control the wireless communicator to transmit, to the external control device, pairing data for the external control device to perform a pairing with the external device, and control code information corresponding to the external device,
in response to a predefined input being received from the external control device, control to display a guide screen corresponding to the external device,
wherein the guide screen guides to execute at least one function of the external device using the external control device.
 
11. A method operating an image display device, the method comprising:
obtaining device identification information corresponding to an external device connected to the image display device;
transmitting, to an external control device, search data for the external control device to perform a discovering process for discovering the external device based on the device identification information;
based on the external device being discovered by the external control device using the search data, transmitting, to the external control device, pairing data for the external control device to perform a pairing with the external device, and control code information corresponding to the external device; and
in response to a predefined input being received from the external control device, displaying a guide screen corresponding to the external device,
wherein the guide screen guides to execute at least one function of the external device using the external control device.
