Abstract

The present specification discloses a display device and a method of controlling the display device. The display device includes a flexible display unit configured to display at least one or more icons and a control unit. If an event occurs in a manner that a partial area of the flexible display unit is overlapped with each other, the control unit can set a symmetrical outer blank area for a predetermined area and consistently arrange a space between the at least one or more icons.

First claim

What is claimed is:

1. A display device, comprising:
a flexible display configured to display at least one or more icons; and
a controller including a processor configured to:
set a symmetrical outer blank area for a predetermined area when an event occurs in a manner that partial areas of the flexible display are overlapped with each other, wherein the overlapped event corresponds to a folding event;
calculate an area of a folded area of the flexible display in response to the folding event and an area of the at least one or more icons;
determine a number of icons to be arranged to the folded area based on the calculated area of the folded area and the calculated area of the at least one or more icons;
consistently arrange a space between the at least one or more icons in the folded area after the symmetrical outer blank area is set;
symmetrically arrange the at least one or more icons in the folded area;
detect the number of icons arranged to the folded area and an arrangement form of the icons;
display an indicator indicating availability of a next page; and
display the next page based on the number of icons and the arrangement form in response to receiving a touch-based flipping command.

2. The display device of claim 1 , wherein the controller is configured to arrange the at least one or more icons in proportion to the size of a folded area of the flexible display.

3. The display device of claim 2 , wherein the controller is configured to arrange the at least one or more icons in a manner of adjusting a size of the at least one or more icons.

4. The display device of claim 2 , wherein the controller is configured to arrange the at least one or more icons in a manner of adjusting the number of the at least one or more icons.

5. The display device of claim 2 , further comprising a sensor configured to track a gaze of a user,
wherein the controller is configured to control the display unit to display at least one or more icons positioned at an area at which the gaze of the user detected by the sensor is located in a manner of enlarging the at least one or more icons.

6. The display device of claim 2 , wherein when area of the folded area corresponds to a predetermined size, the controller is configured to control the display unit to display a predetermined screen on the folded area.

7. The display device of claim 6 , wherein the predetermined screen corresponds to at least one of a home screen, a bookmark screen and a user configuration screen.

8. The display device of claim 1 , wherein the overlapped event corresponds to a rolling event, and
wherein the controller is configured to arrange the at least one or more icons based on an area except an area blocked by a different area among areas of the same flat of the flexible display.

9. The display device of claim 8 , further comprising a sensor configured to track a gaze of a user,
wherein the controller is configured to calculate area of an area of the flexible display where the gaze of the user detected by the sensor is within a predetermined angle range and area of the at least one or more icons and calculate the number of icons to be arranged to the area based on the calculated area of the area and the calculated area of the at least one or more icons.

10. The display device of claim 9 , wherein the controller is configured to control the flexible display to display at least one or more icons positioned at an area at which the gaze of the user detected by the sensor is located in a manner of enlarging the at least one or more icons.

11. The display device of claim 1 , wherein when the flexible display is unfolded, the controller is configured to calculate area of the unfolded flexible display and area of the at least one or more icons and consistently arrange a space between the at least one or more icons based on the calculated area of the unfolded flexible display and the calculated area of the at least one or more icons.

12. The display device of claim 11 , wherein the controller is configured to arrange the at least one or more icons in a manner of adjusting a size of the at least one or more icons.

13. The display device of claim 11 , wherein the controller is configured to set a symmetrical outer blank area of the flexible display.

14. A method of controlling a display device, which contains a flexible display displaying at least one or more icons, comprising:
setting, via a controller, a symmetrical outer blank area for a predetermined area when an event occurs in a manner that partial areas of the flexible display are overlapped with each other, wherein the overlapped event corresponds to a folding event wherein the controller includes a processor;
calculating an area of a folded area of the flexible display in response to the folding event and an area of the at least one or more icons;
determining a number of icons to be arranged to the folded area based on the calculated area of the folded area and the calculated area of the at least one or more icons;
consistently arranging, via the controller, a space between the at least one or more icons after the symmetrical outer blank area is set;
symmetrically arranging the at least one or more icons in the folded area;
detecting the number of icons arranged to the folded area and an arrangement form of the icons;
display an indicator indicating availability of a next page; and
displaying the next page based on the number of icons and the arrangement form in response to receiving a touch-based flipping command.

15. The method of claim 14 , wherein the consistently arranging a space between the at least one or more icons further comprises arranging the at least one or more icons in proportion to a size of the folded area of the flexible display.

16. The method of claim 15 , wherein when the area of the folded area corresponds to a predetermined size, the consistently arranging the space between the at least one or more icons further comprises controlling the display unit to display a predetermined screen on the folded area.

17. The method of claim 14 , further comprising:
unfolding the flexible display; and
calculating an area of the unfolded flexible display and an area of the at least one or more icons and consistently arranging the space between the at least one or more icons based on the calculated area of the unfolded flexible display and the calculated area of the at least one or more icons.
