an electromagnet when the second display region is expanded to a maximum, or

an electromagnetic when the second display region is formed to a minimum.

8. The electronic device of claim 7 , wherein the panel support comprises:

a gear pattern in which the protrusions and troughs are repeated; and

first protrusions protruding in a direction parallel with the display on at least one side of the at least some of the plurality of protrusions.

9. The electronic device of claim 8 , further comprising a protective member disposed between at least one of the first cover or the second cover and the panel support to protect a portion of the display.

10. The electronic device of claim 9 , further comprising an elastic member having one end fixed to one side inside the electronic device and another end connected to an end of the panel support.

11. The electronic device of claim 10 , wherein the panel support comprises:

a substrate portion of a predetermined thickness disposed on the back surface of the display; and

gear peaks repeatedly protruding by a predetermined height on the substrate portion.

12. The electronic device of claim 11 , wherein the portion of the panel support is formed of an elastic material.

13. The electronic device of claim 12 , further comprising a magnetic force-related member disposed at a position adjacent to an inner surface of the panel support.

14. The electronic device of claim 13 , wherein the magnetic force-related member is disposed between the portion of the first display region exposed outside in a state in which the display is wound and the portion of the second display region disposed inside the electronic device.

15. An electronic device for supporting sliding, the electronic device comprising:

a first cover;

a second cover coupled to the first cover to slide;

a display in which a size of an exposed region is changed corresponding to the sliding of the second cover;

a display support member supporting a first region of the display;

a sliding structure at least partially disposed under the display support member;

a first driving unit at least partially coupled to a guide rail formed on a bottom of the display support member and moving the sliding structure in a first direction or a second direction opposite to the first direction;

a panel support including a plurality of protrusions disposed on a back surface of a second region of the display with respect to a front surface of the display on which a screen is displayed;

a second driving unit contacting at least a portion of the panel support and performing a rotation required for winding of the panel support; and

at least one processor configured to control operations of the first driving unit and the second driving unit,

wherein the second driving unit including hook grooves temporarily coupled with the plurality of protrusions when contacting one side of the panel support, and

wherein the plurality of protrusions include a hook portion protruding in a direction opposite to a protruding direction of the hook grooves formed on the second driving unit.

16. The electronic device of claim 15 , wherein the at least one processor is further configured to control the first driving unit and the second driving unit to operate in a counterclockwise direction for a same time period or by a same number of rotations when an event requesting extension of the display occurs.

17. The electronic device of claim 15 , wherein the at least one processor is further configured to, after completing an extension of the display, control the first driving unit to be fixed and the second driving unit to further rotate by a first angle in a clockwise direction.

18. The electronic device of claim 15 , wherein the at least one processor is further configured to control the first driving unit and the second driving unit to operate in a clockwise direction for a same time period or by a same number of rotations when an event requesting reduction of the display occurs.

19. The electronic device of claim 15 , wherein the at least one processor is further configured to control an extension or a reduction of the display according to a user input or a request to execute a specified application.

20. The electronic device of claim 16 , further comprising:

a rotation shaft contacting the portion of the panel support and rotating corresponding to the sliding of the second cover.
