Watch type mobile terminal

1. An electronic device comprising:

a touch screen; and

a controller configured to:

cause the touch screen to display a standby screen in a normal mode, wherein the standby screen includes an analog watch image having an hour hand image, a minute hand image, and numbers for indicating current time, wherein the hour hand image and the minute hand image are moved based on passage of time, and wherein the numbers are fixedly displayed regardless of the passage of time;

receive a touch input applied to the analog watch image in the normal mode;

cause the touch screen to change the standby screen to an ambient screen including a schedule list in response to the touch input, the ambient screen displayed in a low-power mode for decreasing power consumption; and

cause the touch screen to change the ambient screen to the standby screen after a threshold time period elapses since the ambient screen is displayed.

2. The electronic device of claim 1 , wherein when an item is selected from the schedule list, detailed schedule information corresponding to the item is displayed on the touch screen.

3. The electronic device of claim 2 , wherein the schedule list or the detailed schedule information is switched to the analog watch image after the threshold time period elapses since the schedule list or detailed schedule information is displayed.

4. The electronic device of claim 1 , wherein the touch input comprises a drag touch input starting from a central region of the analog watch image.

5. The electronic device of claim 4 , wherein when the drag touch input is applied along the minute hand image from the central region of the analog watch image, a window for inputting a schedule is displayed.

6. The electronic device of claim 1 , wherein the controller is further configured to execute a function related to a phone call in response to a second touch input received via at least one of the numbers in the low-power mode, and

wherein when a specific number among the numbers is touched by the second touch input, missed call information related to a speed dial number corresponding to the specific number is displayed.

7. The electronic device of claim 6 , wherein the missed call information is displayed around the specific number.

8. The electronic device of claim 6 , wherein when a threshold time period elapses without receiving an additional touch input after the missed call information is displayed, different missed call information related to another speed dial number corresponding to a number next to the specific number is displayed.

9. The electronic device of claim 6 , wherein the analog watch image comprises twelve number regions each corresponding to a respective number among the numbers, and each of the twelve number regions is matched to a corresponding one of different twelve speed dial numbers.

10. The electronic device of claim 1 , wherein the touch input comprises tapping a central region on the standby screen.

11. The electronic device of claim 10 , wherein tapping the central region of the standby screen comprises tapping the central region twice.

12. The electronic device of claim 11 , wherein the touch input further comprises a dragging operation from the central region along the hour hand.

13. The electronic device of claim 1 , wherein the analog watch image displayed on the standby screen is displayed differently in the normal mode and the low-power mode.

14. The electronic device of claim 13 , wherein the analog watch image displayed in the low-power mode comprises a less number of components compared to a number of components included in the analog watch image displayed in the normal mode.
