Abstract

An electronic device and a control method therefor are provided. The electronic device comprises: a housing including a roll; a touch display which is wound on a roll, is capable of changing the size of a display area according to the rotation of the roll, and detects a touch of a user; a sensing part for sensing the size of the display area; and a processor which is electrically connected to the display and the sensing part, wherein if the size of the display area increases by the rotation of the roll while a user touch is detected in one area of the touch display while an execution screen of an application is being provided in the display area, the processor may control the touch display so as to provide new information to the display area.

First claim

The invention claimed is:

1. An electronic device comprising:
a housing containing a roll;
a touch display configured to be rolled on the roll, and sense a touch of a user, the touch display comprising a display area having a size that changes according to a rotation of the roll;
a sensor configured to sense the size of the display area; and
a processor electrically connected to the display and the sensor,
wherein the processor is configured to control the touch display to provide new information to the display area, based on the size of the display area being increased according to the rotation of the roll in a state in which the touch of the user is sensed in one area of the touch display, that corresponds to a part of an execution screen of an application, while the execution screen of the application is provided to the display area,
the processor is further configured to control the touch display to provide the new information to an area of the display area positioned at an opposite side of the area in which the touch of the user is sensed, based on a side of the execution screen of the display area in which the touch of the user is sensed, and
the processor is further configured to control the touch display to provide the new information to the display area while maintaining a size of the execution screen of the application.

2. The electronic device as claimed in claim 1 , wherein the processor is further configured to control the touch display to increase the size of the execution screen of the application provided to the display area according to the increase in the size of the display area, based on the size of the display area being increased according to the rotation of the roll in a state in which the touch of the user is not sensed in one area of the touch display while the execution screen of the application is provided to the display area.

3. The electronic device as claimed in claim 1 , wherein the processor is further configured to control the touch display to provide only the execution screen of the application to the display area, based on the size of the display area being reduced according to the rotation of the roll in a state in which the touch of the user is sensed in the area to which the execution screen of the application is provided while the execution screen of the application and the new information are displayed on the display area.

4. The electronic device as claimed in claim 1 , wherein the processor is further configured to control the touch display to provide only the new information to the display area, based on the size of the display area being reduced according to the rotation of the roll in a state in which the touch of the user is sensed in the area to which the new information is provided while the execution screen of the application and the new information are displayed on the display area.

5. The electronic device as claimed in claim 1 , wherein the processor is further configured to control the touch display to reduce the sizes of the execution screen and the new information according to a reduction in the size of the display area, based on the size of the display area being reduced according to the rotation of the roll in a state in which the touch of the user is not sensed in the touch display while the execution screen of the application and the new information are displayed on the display area.

6. The electronic device as claimed in claim 1 , wherein the processor is further configured to control the touch display to provide another information to an area on which the new information is displayed, based on a drag interaction being sensed in the area on which the new information is displayed while the execution screen of the application and the new information are displayed on the display area.

7. The electronic device as claimed in claim 1 , wherein the new information is a menu.

8. A control method for an electronic device including a housing containing a roll and a touch display configured to be rolled on the roll, the touch display comprising a display area having a size that changes according to a rotation of the roll, and the touch display displaying a screen including at least one element on the display area, the control method comprising:
providing an execution screen of an application to the display area;
sensing an increase in a size of the display area according to the rotation of the roll in a state in which a touch of a user is sensed in one area of the touch display that corresponds to a part of the execution screen that is displayed; and
providing new information together with the execution screen of the application to the display area, based on the touch of the user being sensed in the one area while the size of the display area is increased,
wherein the new information is provided to an area of the display area positioned at an opposite side of the area in which the touch of the user is sensed, based on a side of the execution screen of the display area in which the touch of the user is sensed, and
in the providing of the new information, the new information is provided to the display area while a size of the execution screen of the application is maintained.

9. The control method as claimed in claim 8 , further comprising:
sensing the increase in the size of the display area according to the rotation of the roll in a state in which the touch of the user is not sensed in one area of the touch display while the execution screen of the application is provided to the display area; and
increasing a size of the execution screen of the application provided to the display area according to the increase in the size of the display area, based on not sensing the touch of the user in the one area while the size of the display area is increased.

10. The control method as claimed in claim 8 , further comprising:
sensing a reduction in the size of the display area according to the rotation of the roll in a state in which the touch of the user is sensed in the area to which the execution screen of the application is provided while the execution screen of the application and the new information are displayed on the display area; and
providing only the execution screen of the application to the display area, based on the touch of the user being sensed in the area while the size of the display area is reduced.

11. The control method as claimed in claim 8 , further comprising:
sensing a reduction in the size of the display area according to the rotation of the roll in a state in which the touch of the user is sensed in the area to which the new information is provided while the execution screen of the application and the new information are displayed on the display area; and
providing only the new information to the display area, based on the touch of the user being sensed in the area while the size of the display area is reduced.

12. The control method as claimed in claim 8 , further comprising:
sensing a reduction in the size of the display area according to the rotation of the roll in a state in which the touch of the user is not sensed in the touch display while the execution screen of the application and the new information are displayed on the display area; and
reducing the size of the execution screen and the new information according to the reduction in the size of the display area and providing the reduced execution screen and the new information, based on not sensing the touch of the user in the touch display while the size of the display area is reduced.
