Abstract

A display device that incorporates a supplemental flexible display that is stored within a main body of the display device is presented that is able to optimize the operation of the display device by controlling an application that is displayed on the supplemental flexible display. The display device is optimized by relating certain applications as being optimized to be displayed for certain display sizes, where the display size is determined by a pulled out length of the supplemental flexible display. This is done because a display size may have a significant impact on the effectiveness of certain applications.

Claims

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

displaying a main application on a main display;

exposing the flexible display from the display device;

displaying a first application in the first-sized flexible display when a display size of the exposed flexible display is a first size;

switching from the first application to a second application when the display size of the exposed flexible display is changed from the first size to a second size;

displaying the second application in the second-sized flexible display;

displaying at least one identifier identifying an application that is designated to be executed and displayed on the flexible display when the display size of the flexible display is the first size; and

selecting the identifier,

wherein the selected identifier identifies the first application,

wherein the first application provides first information and the second application provides second information, and the first information and the second information are associated with information of the main application respectively,

wherein the first information and the second information are different from each other,

wherein the first information and second information are not a continuation of information provided in the main application displayed on the main display, and

wherein the first application and the second application are determined to be optimal based on at least one of an available resolution of the exposed flexible display within a determined display area and screen size of a determined display area.

2. The method of claim 1, further comprising:

storing, in a storage unit, a first list of applications that are designated to be executed and displayed on the flexible display when the display size of the flexible display is the first size, wherein the first application is included in the first list.

3. The method of claim 1, further comprising:

recording, in a storage unit, history information identifying the frequency with which applications are executed and displayed on the flexible display when the display size of the flexible display is the first size; and

referencing the history information, and executing and displaying an application on the flexible display that has been executed and displayed on the flexible display with the highest frequency when the display size of the flexible display is the first size, wherein the first application is the application that has been executed and displayed on the flexible display with the highest frequency when the display size of the flexible display is the first size.

4. The method of claim 1, wherein the main application provides profile information of a person on a contact list stored in a storage unit, and the first application displays additional information on the person on the contact list.

5. The method of claim 1, further comprising:

returning the flexible display into the display device; and

executing the first application and displaying the first application on the flexible display when the display size of the flexible display is back to the first size.

6. The method of claim 1, wherein the second application is one of a music playing application, a remote control application, mapping application, a web browsing application, a book reading application and a video player application.

7. The method of claim 1, further comprising:

continuing to expose the flexible display from the display device; and

executing a third application and displaying the third application on the flexible display when the display size of the flexible display is third size.

8. The method of claim 1, wherein when the first application is switched to the second application, display attributes of the main application are maintained.

9. A display device, the display device comprising:

a main display configured to display a main application;

a flexible display configured to be exposed from the display device; and

a system controller configured to display a first application in the first-sized flexible display when a display size of the exposed flexible display is a first size,

wherein the system controller is configured to switch from the first application to a second application and display the second application which is different from the first application in the second-sized flexible display when the display size of the exposed flexible display is changed from the first size to a second size,

wherein the first application provides first information and the second application provides second information, and the first information and the second information are associated with information of the main application respectively,

wherein the first information and the second information are different from each other,

wherein the first information and second information are not a continuation of information provided in the main application displayed on the main display,

wherein the first application and the second application are determined to be optimal based on at least one of an available resolution of the exposed flexible display within a determined display area and screen size of a determined display area,

wherein the flexible display is further configured to display at least one identifier identifying an application that is designated to be executed and displayed on the flexible display when the display size of the flexible display is the first size, and the system controller is configured to recognize a selection of the identifier displayed on the flexible display, and

wherein the selected identifier identifies the first application.

10. The display device of claim 9, further comprising:

a storage unit configured to store a first list of applications that are designated to be executed and displayed on the flexible display when the display size of the flexible display is the first size, wherein the first application is included in the first list.

11. The display device of claim 9, further comprising:

a storage unit configured to record history information identifying the frequency with which applications are executed and displayed on the flexible display when the display size of the flexible display is the first size, and

the system controller is further configured to reference the history information, and execute and control the display of an application on the flexible display that has been executed and displayed on the flexible display with the highest frequency when the display size of the flexible display is the first size, wherein the first application is the application that has been executed and displayed on the flexible display with the highest frequency when the display size of the flexible display is the first size.

12. The display device of claim 9, wherein the main application provides profile information of a person on a contact list stored in a storage unit, and the first application displays additional information on the person on the contact list.

13. The display device of claim 9, wherein the system controller is further configured to execute and control the display of the first application on the flexible display when the display size of the flexible display is back to the first size.

14. The display device of claim 9, wherein the second application is one of a music playing application, a remote control application mapping application, a web browsing application, a book reading application and a video player application.

15. The display device of claim 9, wherein the system controller is further configured to execute and control a display of a third application on the flexible display when the display size of the flexible display is the third size.

16. The display device of claim 9, wherein when the first application is switched to the second application, display attributes of the main application are maintained.
