The display apparatus includes a communicator including a circuitry; a display; a motor configured to rotate the display; a memory storing at least one instruction; and a processor configured to execute the at least one instruction to: control the communicator to communicatively connect to an external device based on information related to the display apparatus that is received by the external device from a remote controller to which the external device is tagged, obtain direction information of at least one of the external device and of an image content displayed on the external device, determine, based on the direction information, whether to control the motor to rotate the display, and control the display to display the image content that is received from the external device through the communicator. ## Claims ### Claim 1 A display apparatus comprising: a communicator including a circuitry; a display; a motor; a memory storing at least one instruction; and a processor configured to execute the at least one instruction to: in response to an external device being tagged to the communicator, control the communicator to establish a communicative connection with the external device, obtain, from the external device, an image content displayed on the external device and direction information indicating an orientation of the external device, identify, based on the direction information of the external device, whether to rotate the display, and control the motor to rotate the display based on whether to rotate the display and control the display to display the image content. ### Claim 2 (depends on 1) The display apparatus of claim 1, wherein the processor is further configured to execute the at least one instruction to receive, from the external device through the communicator, the information related to the external device, and to connect to the external device based on the information related to the external device. ### Claim 3 (depends on 1) The display apparatus of claim 1, wherein the communicator includes a near field communication (NFC) tag. ### Claim 4 (depends on 1) The display apparatus of claim 1, wherein the processor is further configured to execute the at least one instruction to: based on a determination that a direction of the external device does not coincide with a direction of the display according to the direction information, control the motor to rotate the display and control the display to display the image content on the rotated display; and based on a determination that the direction of the external device coincides with the direction of the display according to the direction information, control the display to display the image content without rotating the display. ### Claim 5 (depends on 4) The display apparatus of claim 4, wherein the processor is further configured to execute the at least one instruction to: based on the display being in a landscape direction and the direction of the display not coinciding with the direction of the external device, control the motor to rotate the display to a portrait direction; and based on the display being in the portrait direction and the direction of the display not coinciding with the direction of the external device, control the motor to rotate the display to the landscape direction. ### Claim 6 (depends on 4) The display apparatus of claim 4, wherein the processor is further configured to execute the at least one instruction to, based on a determination that the direction of the external device does not coincide with the direction of the display, control the display to display a user interface (UI) item for selecting whether to rotate the display. ### Claim 7 (depends on 1) The display apparatus of claim 1, wherein the processor is further configured to execute the at least one instruction to, based on a direction of the external device being changed while the image content is being displayed on the display, receive changed direction information from the external device through the communicator, and control the motor to rotate the display according to the changed direction information. ### Claim 8 (depends on 1) The display apparatus of claim 1, wherein the processor is further configured to execute the at least one instruction to: control the display to display a UI for selecting whether to rotate the display, based on a display direction of the image content being determined to be different from a direction of the display. ### Claim 9 (depends on 1) The display apparatus of claim 1, wherein the processor is further configured to execute the at least one instruction to control the display to display the image content while maintaining a ratio of the image content during rotation of the display. ### Claim 10 A controlling method of a display apparatus comprising a communicator and a display, the method comprising: in response to an external device being tagged to the communicator, establishing a communicative connection with the external device; obtaining, from the external device, an image content displayed on the external device and direction information indicating an orientation of the external device; identifying, based on the direction information of the external device, whether to rotate a display of the display apparatus; and controlling to rotate the display based on the identifying whether to rotate the display and displaying the image content. ### Claim 11 (depends on 10) The controlling method of claim 10, wherein the connecting comprises: receiving, from the external device, the information related to the external device, and connecting to the external device based on the information related to the external device. ### Claim 12 (depends on 10) The controlling method of claim 10, wherein the communicator includes a near field communication (NFC) tag. ### Claim 13 (depends on 10) The controlling method of claim 10, wherein the controlling to rotate the display comprises: based on a determination that a direction of the external device does not coincide with a direction of the display according to the direction information, controlling to rotate the display and displaying the image content on the rotated display; and based on a determination that the direction of the external device coincides with the direction of the display according to the direction information, determining to display the image content without rotating the display. ### Claim 14 (depends on 13) The controlling method of claim 13, wherein the controlling to rotate the display comprises: based on the display being in a landscape direction and the direction of the display not coinciding with the direction of the external device, controlling to rotate the display to a portrait direction; and based on the display being in the portrait direction and the direction of the display not coinciding with the direction of the external device, controlling to rotate the display to the landscape direction. ### Claim 15 (depends on 10) The controlling method of claim 10, wherein the controlling to rotate the display comprises: based on a direction of the external device being changed while the image content is being displayed on the display, receiving changed direction information from the external device, and controlling to rotate the display according to the received changed direction information. ### Claim 16 (depends on 13) The controlling method of claim 13, wherein the controlling to rotate the display comprises: based on a determination that the direction of the external device does not coincide with the direction of the display, displaying a user interface (UI) item for selecting whether to rotate the display. ### Claim 17 (depends on 10) The controlling method of claim 10, wherein: the identifying whether to rotate the display comprises displaying a UI for selecting whether to rotate the display, based on a display direction of the image content being determined to be different from a direction of the display. ### Claim 18 (depends on 10) The controlling method of claim 10, wherein the displaying the image content comprises: displaying the image content while maintaining a ratio of the image content during rotation of the display.
