a memory storing one or more instructions; and

at least one processor comprising processing circuitry and configured to execute the one or more instructions to:

obtain display information corresponding to a plurality of regions included in a screen of the display,

control the communication interface to transmit first display information corresponding to a first region among the plurality of regions to a first electronic device corresponding to the first region among the plurality of electronic devices and transmit second display information corresponding to a second region among the plurality of regions to a second electronic device corresponding to the second region among the plurality of electronic devices,

receive, from the first electronic device, a first image obtained based on the first display information and receive, from the second electronic device, a second image obtained based on the second display information,

control the display to display the first image in the first region and the second image in the second region, and

based on identifying that a layout of the screen is changed, control the communication interface to transmit changed first display information corresponding to the first region to the first electronic device and transmit changed second display information corresponding to the second region to the second electronic device.

2. The display device of claim 1 , wherein

the at least one processor is further configured to execute the one or more instructions to:

control the display to display a list including external electronic devices connected to the display device, and

determine the plurality of electronic devices based on receiving an input for selecting at least one of the external electronic devices included in the list.

3. The display device of claim 1 , wherein the at least one processor is further configured to execute the one or more instructions to: determine the layout of the screen based on the number of the plurality of electronic devices, and determine the plurality of regions included in the screen according to the layout.

4. The display device of claim 1 , wherein

the at least one processor is further configured to execute the one or more instructions to:

control the display to display a layout list including a plurality of layouts, and

determine the layout of the screen based on receiving an input for selecting the layout included in the layout list, and determine the plurality of regions included in the screen according to the layout.

5. The display device of claim 1 , wherein

the first image includes an image obtained by scaling, based on the first display information, an image in a region to be shared on a screen displayed on the first electronic device, and

the second image includes an image obtained by scaling, based on the second display information, an image in a region to be shared on a screen displayed on the second electronic device.

6. The display device of claim 1 , wherein

the at least one processor is further configured to execute the one or more instructions to:

monitor cessation of sharing of the screens of the first electronic device and the second electronic device, and

change the layout of the screen based on the cessation of the sharing of the screen of at least one of the first electronic device or the second electronic device.

7. The display device of claim 1 , wherein the at least one processor is further configured to execute the one or more instructions to:

monitor addition of a third electronic device whose screen is shared on the display device, and

change the layout of the screen based on the addition of the third electronic device.

8. The display device of claim 1 , wherein the at least one processor is further configured to execute the one or more instructions to:

receive a user input for changing at least one of a size, a location, a resolution, or an aspect ratio of the at least one of the first region or the second region,

change the layout of the screen based on the user input.

9. The display device of claim 1 , wherein the first display information includes at least one of a size, a resolution, or an aspect ratio of the first region and the second display information includes at least one of a size, a resolution, or an aspect ratio of the second region.

10. The display device of claim 1 , wherein the at least one processor is further configured to execute the one or more instructions to:

receive, from the first electronic device, a third image obtained based on the changed first display information and receive, from the second electronic device, a fourth image obtained based on the changed second display information, and

control the display to display the third image in the first region and the fourth image in the second region.

11. A method of operating a display device for sharing screens of a plurality of electronic devices, the method comprising:

obtaining of display information corresponding to a plurality of regions included in a screen of the display;

transmitting first display information corresponding to a first region among the plurality of regions to a first electronic device corresponding to the first region among the plurality of electronic devices;

transmitting second display information corresponding to a second region among the plurality of regions to a second electronic device corresponding to the second region among the plurality of electronic devices;

receiving, from the first electronic device, a first image obtained based on the first display information;

receiving, from the second electronic device, a second image obtained based on the second display information;

displaying the first image in the first region and the second image in the second region; and

based on identifying that a layout of the screen is changed, transmitting changed first display information corresponding to the first region to the first electronic device and transmitting changed second display information corresponding to the second region to the second electronic device.

12. The method of claim 11 , further comprising:

displaying a list including external electronic devices connected to the display device; and

determining the plurality of electronic devices based on receiving an input for selecting at least one of the external electronic devices included in the list.

13. The method of claim 11 , further comprising

determining the layout of the screen based on the number of the plurality of electronic devices,

determining the plurality of regions included in the screen according to the layout.

14. The method of claim 11 , further comprising:

displaying a layout list including a plurality of layouts; and

determining the layout of the screen based on receiving an input for selecting the layout included in the layout list,

determining the plurality of regions included in the screen according to the layout.

15. The method of claim 11 , wherein

the first image includes an image obtained by scaling, based on the first display information, an image in a region to be shared on a screen displayed on the first electronic device, and

the second image includes an image obtained by scaling, based on the second display information, an image in a region to be shared on a screen displayed on the second electronic device.

16. The method of claim 11 , further comprising:

monitoring cessation of sharing of the screens of the first electronic device and the second electronic device; and

changing the layout of the screen based on the cessation of the sharing of the screen of at least one of the first electronic device or the second electronic device.

17. The method of claim 11 , further comprising:

monitoring addition of a third electronic device whose screen is shared on the display device; and

changing the layout of the screen based on the addition of the third electronic device.

18. A non-transitory computer-readable recording medium having stored therein a program for performing operations corresponding to the method of claim 11 .

19. The method of claim 11 , further comprising:

receiving, from the first electronic device, a third image obtained based on the changed first display information and receiving, from the second electronic device, a fourth image obtained based on the changed second display information, and
