Abstract

The present invention relates to a mobile terminal and a method for controlling the same which can effectively reduce an afterimage phenomenon generated on a display unit. A control apparatus of a mobile terminal for reducing an afterimage of a display unit of the mobile terminal according to embodiments of the present invention may comprise: the display unit for displaying items in a turned-on state; and a control unit for turning off the display unit after displaying the items on the display unit, moving display locations of the items displayed on the display unit in the turned-on state in a state where the display unit is turned off, and displaying the items in the moved display locations when the display unit is turned back on.

Claims

1. A control apparatus of a mobile terminal for reducing image sticking on a display unit of the mobile terminal, the control apparatus comprising:

a display unit configured to display items in a turn-on state; and

a controller configured to display the items on the display unit and then turn off the display unit, and move the display position of the items displayed on the display unit in the turn-on state in a state that the display unit is turned off, and display the items at the moved display position when the display unit is turned back on.

2. The control apparatus of claim 1, wherein the controller counts a turn-off number of times of the display unit, and sequentially moves the display position of the items according to the counted number of times.

3. The control apparatus of claim 1, wherein the items are icons indicating the current status information of the mobile terminal.

4. The control apparatus of claim 3, wherein the icons comprises:

at least one of a mobile communication network reception sensitivity display icon, a long term evolution (LTE) or WiFi reception sensitivity display icon, a current time display icon, a battery information display icon, an alarm setting display icon, a Bluetooth status display icon, and a global positioning system (GPS) status display icon.

5. The control apparatus of claim 1, wherein the controller displays a preset image for reducing image sticking instead of a home image containing the items for a preset period of time, and moves the display position of the items, and displays the items at the moved display position when the preset period of time has passed.

6. The control apparatus of claim 4, wherein the controller displays a preset image for a preset period of time instead of a first image corresponding to a region containing the items to reduce image sticking, and moves the display position of the items, and displays the items at the moved display position when the preset period of time has passed.

7. The control apparatus of claim 1, wherein the controller periodically displays only partial items of the items on the display unit, and periodically changes the display position of the partial items.

8. The control apparatus of claim 1, wherein the controller moves the display position of the items by a preset distance whenever a screen vertical view mode or screen horizontal view mode of the mobile terminal is selected.

9. The control apparatus of claim 1, further comprising:

a sensing unit configured to sense an acceleration of the mobile terminal,

wherein the controller moves the display position of the items by a preset distance whenever the sensed acceleration exceeds a preset reference value.

10. The control apparatus of claim 1, wherein the controller detects a user'"'"'s line of sight through a camera, and displays the items at the moved display position only when the detected user'"'"'s line of sight does not face a screen of the display unit.

11. The control apparatus of claim 1, further comprising:

a wireless communication unit configured to receive information,

wherein the controller changes the display position of the items when the information is received.

12. The control apparatus of claim 1, wherein the controller moves the display position of the items by a preset distance whenever a text or call signal is received through the wireless communication unit.

13. A method for reducing image sticking on a display unit of a mobile terminal, the method comprising:

displaying items on the display unit in a turn-on state;

displaying the items on the display unit and then turning off the display unit;

moving the display position of the items displayed on the display unit in the turn-on state in a state that the display unit is turned off; and

displaying the items at the moved display position when the display unit is turned on.

14. The method of claim 13, further comprising:

counting a turn-off number of times of the display unit; and

sequentially moving the display position of the items according to the counted number of times,

wherein the items are icons indicating the current status information of the mobile terminal.

15. The method of claim 14, wherein the icons comprises:

at least one of a mobile communication network reception sensitivity display icon, a long term evolution (LTE) or WiFi reception sensitivity display icon, a current time display icon, a battery information display icon, an alarm setting display icon, a Bluetooth status display icon, and a global positioning system (GPS) status display icon.

16. The method of claim 15, further comprising:

displaying a preset image for reducing image sticking instead of a home image containing the items for a preset period of time; and

moving the display position of the items, and displaying the items at the moved display position when the preset period of time has passed.

17. The method of claim 13, further comprising:

displaying a preset image for a preset period of time instead of a first image corresponding to a region containing the items to reduce image sticking; and

moving the display position of the items, and displaying the items at the moved display position when the preset period of time has passed.

18. The method of claim 13, further comprising:

periodically displaying only partial items of the items on the display unit; and

periodically changing the display position of the partial items.

19. The method of claim 13, further comprising:

moving the display position of the items by a preset distance whenever a screen vertical view mode or screen horizontal view mode of the mobile terminal is selected.

20. The method of claim 13, further comprising:

sensing an acceleration of the mobile terminal; and

moving the display position of the items by a preset distance whenever the sensed acceleration exceeds a preset reference value.
