Abstract

A display device including a touch screen configured to display an analog watch screen; a wireless communication unit configured to receive data from an external device; a sensing unit configured to sense at least one of a motion of the display device and biometric state information of a user; and a controller configured to switch the analog watch screen to a digital watch screen in response to at least one of a predetermined touch input on the touch screen, an amount of data received from the external device, a specific motion of the display device sensed by the sensing unit, and specific biometric state information of the user sensed by the sensing unit.

Claims

1. A display device, comprising:

switch the analog watch screen to a digital watch screen in response to at least one of a predetermined touch input on the touch screen, an amount of data received from the external device, a specific motion of the display device sensed by the sensing unit, and specific biometric state information of the user sensed by the sensing unit.

2. The display device of claim 1, wherein the amount of data received corresponds to a preset number of data received from the external device, the predetermined touch input corresponds to one of a selection of an icon corresponding to the received data and a touch to a preset region of the touch screen, the specific motion of the display device corresponds to a sway of the display device over a preset strength, and the biometric state information of the user corresponds to a sensing of a BPM (beats per minute) of the user over a preset count.

3. The display device of claim 2, wherein the controller is further configured to switch the digital watch screen back to the analog watch screen in response to a preset time expiring or an additional input not being applied after the analog watch screen was switched to the digital watch screen.

4. The display device of claim 3, wherein the controller is further configured to display an icon related to the received data at a location on the analog watch screen mapped to a reception time of the received data.

5. The display device of claim 4, wherein the controller is further configured to display the icon by differentiating a size of the icon based on an importance of the received data.

6. The display device of claim 4, wherein the controller is further configured to display a content of the received data on the touch screen in response to a touch input on the displayed icon.

7. The display device of claim 2, wherein the controller is further configured to:

set a switching prohibited time of the display device not to switch the analog watch screen to the digital watch screen for a preset time period, and

maintain the analog watch screen without switching to the digital watch screen in response to the amount of preset number of data received from the external device being received during the preset time period while the display device is set not to switch the analog watch screen to the digital watch screen.

8. The display device of claim 7, wherein the controller is further configured to set the switching prohibited time to a time between the user'"'"'s sleep start time and the user'"'"'s sleep end time by determining a presence or non-presence of the user'"'"'s sleep based on the sensed biometric state information.

9. The display device of claim 2, wherein the controller is further configured to:

display information in a preset first size by switching the analog watch screen to the digital watch screen, in response to the sensed motion of the display device indicating the display device sways over a first strength or the BPM is over a first count, and

display the information in a second size larger than the first size in response to sensed motion of the display device indicating the display device sways over a second strength greater than the first strength or the BPM is over a second count greater than the first count.

10. The display device of claim 9, wherein the controller is further configured to:

display the information in the first size on the digital watch screen having the information displayed in the second size thereon, in response to the sensed motion of the display device indicating the display device sways with a strength equal to or greater than the first strength and smaller than the second strength or the BPM is equal to or greater than the first count and smaller than the second count, and

switch the digital watch screen to the analog watch screen in response to the sensed motion of the display device indicating the mobile terminal sways with the strength smaller than the first strength or the BPM is smaller than the first count is detected.

11. The mobile terminal of claim 1, wherein the controller is further configured to switch the analog watch screen to the digital watch screen in response to an input alarm time and an actual time.

12. A method of controlling a display device, the method comprising:

displaying, via a touch screen of the display device, an analog watch screen;

receiving, via a wireless communication unit of the mobile terminal, data from an external device;

sensing, via a sensing unit of the mobile terminal, at least one of a motion of the display device and biometric state information of a user; and

switching, via a controller of the mobile terminal, the analog watch screen to a digital watch screen in response to at least one of a predetermined touch input on the touch screen, an amount of data received from the external device, a specific motion of the display device sensed by the sensing unit, and specific biometric state information of the user sensed by the sensing unit.

13.
