the event is scheduled to occur at the external display device; and

the controller is further configured to:

move the displayed first item to a second position on the displayed clock screen corresponding to an adjusted occurrence item in response to an adjusting input to the displayed first item for adjusting the occurrence time; and

transmit information to the external display device via the wireless communication unit to change the event to occur at the external display device at the adjusted occurrence time in response to the displayed first item being moved to the second position.

3. The watch-type mobile terminal according to claim 1 , wherein the received information comprises at least an application executed by the external display device during the period of use or a file accessed by the external display device during the period of use.

4. The watch-type mobile terminal according to claim 3 , wherein the controller is further configured to cause the display to display detailed information corresponding to the displayed second item in response to an input for displaying the detailed information.

5. The watch-type mobile terminal according to claim 1 , wherein the controller is further configured to:

receive a notification indicating use of the external display device from the external display device via the wireless communication unit when a distance between the mobile terminal and the external display device is greater than a threshold distance;

cause the display to display information of the received notification; and

transmit a wait screen command or a history storage command to the external display device via the wireless communication unit,

wherein the wait screen command corresponds to changing a screen of the external display device to a wait screen, and

wherein the history storage command corresponds to storing usage history information of the external display device in a memory.

6. The watch-type mobile terminal according to claim 1 , further comprising a motion sensor configured to sense motion of the mobile terminal, wherein

the controller is further configured to transmit a wait screen release command to the external display device via the wireless communication unit when a motion of the mobile terminal sensed via the sensor corresponds to a predetermined wait screen release motion.

7. The watch-type mobile terminal according to claim 1 , wherein the controller is further configured to:

cause the display to display an operation setting window for setting operation of the external display device after the event occurs in response to a selection of the displayed first item; and

transmit an operation command to the external display device via the wireless communication unit, the operation command corresponding to an operation setting selected via the displayed operation setting window.

8. The watch-type mobile terminal according to claim 7 , wherein:

the controller is further configured to cause the display to display a time setting window for setting a time of operation corresponding to the selected operation setting; and

the operation command transmitted to the external display device comprises information of a time of operation selected via the displayed time setting window.

9. A method of operating a watch-type mobile terminal, the method comprising:

displaying a clock screen;

establishing connection with an external display device;

receiving information related to an occurrence time of an event from the external display device; and

displaying a first item corresponding to the event at a first position on the displayed clock screen corresponding to the occurrence time based on the received information,

receiving, from the external display device, information of a period of use of the external display device during a disconnection period when a connection between the watch-type mobile terminal and the external display device is reestablished after the disconnection period; and

displaying a second item corresponding to the received information at a position on the clock screen corresponding to the period of use,

wherein the second item indicates the period of use corresponding to a range from a use start time to a use end time on the clock screen.

10. The method according to claim 9 , wherein:

the event is scheduled to occur at the external display device; and

the method further comprises:

moving the displayed first item to a second position on the displayed clock screen corresponding to an adjusted occurrence time in response to an adjusting input to the displayed first item for adjusting the occurrence time; and

transmitting information to the external display device to change the event to occur at the external display device at the adjusted occurrence time in response to the displayed first item being moved to the second position.

11. The method according to claim 9 , wherein the received information comprises at least an application executed by the external display device during the period of use or a file accessed by the external display device during the period of use.

12. The method according to claim 11 , further comprising displaying detailed information corresponding to the displayed second item in response to an input for displaying the detailed information.

13. The method according to claim 9 , wherein the method further comprises:

receiving, from the external display device, a notification indicating use of the external display device when a distance between the mobile terminal and the external display device is greater than a threshold distance;

displaying information of the received notification; and

transmitting a wait screen command or a history storage command to the external display device,

wherein the wait screen command corresponds to changing a screen of the external display device to a wait screen, and

wherein the history storage command corresponds to storing usage history information of the external display device in a memory.

14. The method according to claim 9 , wherein the method further comprises transmitting a wait screen release command to the external display device when a motion of the mobile terminal sensed via a sensor corresponds to a predetermined wait screen release motion.

15. The method according to claim 9 , further comprising:

displaying an operation setting window for setting operation of the external display device after the event occurs in response to a selection of the displayed first item; and

transmitting an operation command to the external display device, the operation command corresponding to an operation setting selected via the displayed operation setting window.

16. A machine-readable non-transitory medium having stored thereon machine-executable instructions for:

displaying a clock screen;

establishing connection with an external display device;

receiving information related to an occurrence time of an event from the external display device; and

displaying a first item corresponding to the event at a first position on the displayed clock screen corresponding to the occurrence time based on the received information,

receiving, from the external display device, information of a period of use of the external display device during a disconnection period when a connection between the watch-type mobile terminal and the external display device is reestablished after the disconnection period; and

displaying a second item corresponding to the received information at a position on the clock screen corresponding to the period of use,
