Abstract

A display device that incorporates a supplemental display screen that is stored within a main body of the display device must be able to transition objects displayed on a main display to a supplemental display. As the supplemental display is pulled out from storage within the main body of the display device, objects that were displayed on the main display may be transitioned onto the supplemental display. Various methods for transitioning the display of objects on the main display to the supplemental display are discussed, where methods may take into account the length of the supplemental display that is pulled out from storage and also touch input contacts that are made on either one of the displays.

Claims

1. A method of controlling a display of a plurality of icon sheets on a display device with a first display and a second display, the method comprising:

displaying a first icon sheet on the first display;

detecting a touch input contact on the first display;

exposing the second display for display, wherein the second display is provided by a flexible display;

measuring a length of the second display that is exposed for display;

displaying the first icon sheet on the second display while displaying a second icon sheet on the first display, when the measured length of the second display that is exposed is a first length, and the touch input contact is not continually detected on the first display until the second display is exposed to the first length; and

displaying the second icon sheet on the second display while maintaining the display of the first icon sheet on the first display, when the measured length of the second display is exposed to the first length and the touch input contact is continually detected on the first display until the second display is exposed to the first length.

2. The method of claim 1, wherein the second display is stored within a housing unit and pulled out from within the housing unit.

3. The method of claim 1, further comprising:

displaying an indicator on the first display configured to indicate the first icon sheet is displayed on the first display out of a total number of available icon sheets.

4. The method of claim 3, wherein the indicator is only displayed on the first display.

5. The method of claim 3, wherein the indicator further indicates a number of currently displayed icon sheets.

6. The method of claim 1, wherein the first length is at least equal to a width length of the first display.

7. The method of claim 6, wherein only a portion of the second icon sheet is displayed on the second display when the measured length of the second display that is exposed is less than the first length.

8. The method of claim 1, further comprising:

displaying a third icon sheet on the second display when the second display is further exposed to a second length; and

maintaining the display of the first icon sheet on the first display.

9. The method of claim 8, wherein the second length is at least equal to twice a width length of the first display.

10. A method of controlling a display of a plurality of icon sheets on a display device with a first display and a second display, the method comprising:

displaying a first icon sheet on the first display, wherein the second display is provided by a flexible display;

detecting a touch input contact on the first display, wherein the touch input contact overlaps the display of the first icon sheet;

exposing the second display;

measuring a length of the second display that is exposed for display;

displaying the first icon sheet on the second display when the measured length of the second display that is exposed is a first length, and the touch input contact is not continually detected on the first display; and

displaying a third icon sheet on the second display while maintaining the display of the first icon sheet on the first display, when the second display is exposed to a second length and the touch input contact is continually detected on the first display until the second display is exposed to the second length.

11. The method of claim 10, wherein the first length is at least equal to a width length of the first display.

12. The method of claim 10, further comprising:

displaying a third icon sheet on the first display when the second display is further exposed to a second length; and

maintaining the display of the first icon sheet on the second display.

13. The method of claim 10, wherein the second length is at least equal to twice a width length of the first display.

14. A display device, comprising:

a first display on a body of the display device, the first display configured to display a first icon sheet;

a second display provided by a flexible display;

a touch detecting unit configured to detect a touch input contact on the first display;

a measuring unit configured to measure a length of the second display that is exposed for display, and

a processor configured to control the second display to display the first icon sheet while displaying a second icon sheet on the first display, when the second display is exposed to a first length and the touch input contact is not continually detected on the first display until the second display is exposed to the first length, and

to control the second display to display a the second icon sheet on the second display while maintaining the display of the first icon sheet on the first display, when the measured length of the second display is exposed is at least equal to the first length and the touch detecting unit continually detects the touch input contact on the first display until the second display is exposed to the first length.

15. The display device of claim 14, wherein the second display is housed within a housing unit, and the second display is exposed by pulling the second display out from within the housing unit.

16. The display device of claim 14, wherein the first length is at least equal to a width length of the first display.

17. A display device, comprising:

a first display on a body of the display device, the first display configured to display a first icon sheet;

a second display provided by a flexible display;

a touch input detecting unit configured to detect a touch input contact on the first display, wherein the touch input contact overlaps the display of the first icon sheet;

a measuring unit configured to measure a length of the second display that is exposed for display; and

a processor configured to control the second display to display the first icon sheet when the second display is exposed to a first length and the touch input detecting unit does not continually detect the touch input contact on the first display, and to control the first display to display a third icon sheet on the second display while maintaining the display of the first icon sheet on the first display, when the measured length of the second display, that is exposed is the second length, and the touch input detecting unit continually detects the touch input contact on the first display until the second display is exposed to the second length.

18. The display device of claim 17, wherein the second display is housed within a housing unit, and the second display is exposed by pulling the second display out from within the housing unit.

19. The display device of claim 17, wherein the first length is at least equal to a width length of the first display.
