Abstract

An electronic device includes: a variable display having a main display region visible out of the electronic device, wherein a size of the main display region may be reduced from a first display region to a second display region, and including a touch screen panel serving as a first input device, and at least one processor, comprising processing circuitry, electrically connected to the variable display. At least one processor, individually and/or collectively, is configured to control the display to: display a cursor in the main display region and move the cursor into the second display region and display the cursor, based on identifying the main display region being reduced in size from the first display region to the second display region, based on the cursor being positioned in the first display region other than the second display region, in the state that the size of the main display region corresponds to the first display region.

Claims (39)

1 . An electronic device comprising:

a flexible display having a first flexible region and a second flexible region extended from one side of the first flexible region,

wherein, in a state in which entire of the second flexible region is inserted into the electronic device, the first flexible region that is visible through a first surface is provided as a first display region, and

wherein, in a state in which a part of the second flexible region is inserted into the electronic device, the first flexible region and at least a portion of the second flexible region that visible through the first surface are provided as a second display region;

memory storing instructions; and

at least one processor, comprising processing circuitry, operatively connected to the flexible display and the memory,

wherein at least one processor, individually and/or collectively, is configured to:

determine whether a display region of the flexible display is changed from the first display region to the second display region while a cursor is output through the first flexible region,

in response to determining that the display region is changed to the second display region, determine a position of the cursor based on a size of the second display region, and

move the cursor based on the determined position of the cursor.

2 . The electronic device of claim 1 , wherein at least one processor, individually and/or collectively, is configured to:

move the cursor into the first flexible region and output the moved cursor using relative coordinates wherein the relative coordinates are obtained based on an expanding ratio of the display region, based on the change of the display region to the second display region being identified, while the cursor is being displayed using absolute coordinates wherein the absolute coordinates are obtained based on a reference line located on a side of the first flexible region.

3 . The electronic device of claim 2 , wherein at least one processor, individually and/or collectively, is configured to:

based on using relative coordinates, determine coordinates of the cursor using the expanding ratio, wherein the expanding ratio is a ratio between a first length for the first flexible region and at least the portion of the second flexible region provided as the second display region and a second length for the first flexible region provided as the first display region.

4 . The electronic device of claim 1 , wherein at least one processor, individually and/or collectively, is configured to:

output the cursor through a control region set to correspond to the first display region,

based on the display region of the flexible display being changed to the first display region, reset the control region corresponding to the second display region.

5 . The electronic device of claim 4 , wherein at least one processor, individually and/or collectively, is configured to:

move a position of the cursor, based on the reset of control region, based on the control region being reset to correspond to the first display region.

6 . The electronic device of claim 1 , wherein at least one processor, individually and/or collectively, is configured to:

move the cursor within the first flexible region while the display region is changed to the second display region.

7 . The electronic device of claim 1 , wherein at least one processor, individually and/or collectively, is configured to:

based on the change of the display region to the first display region being identified, while the cursor is being displayed using absolute coordinates,

move the cursor to a random position of the first flexible region and output the moved cursor; or

move the cursor to a designated portion of the first flexible region adjacent to the second flexible region and output the moved cursor.

8 . An operation method of an electronic device including a flexible display having a first flexible region and a second flexible region extended from one side of the first flexible region, wherein, in a state in which entire of the second flexible region is inserted into the electronic device, the first flexible region that is visible through a surface is provided as a first display region, and wherein, in a state in which a part of the second flexible region is inserted into the electronic device, the first flexible region and at least a portion of the second flexible region that visible through the first surface are provided as a second display region, the operation method comprising:

determining whether a display region of the flexible display is changed from the first display region to the second first display region while a cursor is output through the first flexible region;

in response to determining that the display region is changed to the second first-display region, determining a position of the cursor based on a size of the second display region; and

moving the cursor based on the determined position of the cursor.

9 . The operation method of claim 8 , further comprising:

moving the cursor into the first flexible region and output the moved cursor using relative coordinates wherein the relative coordinates are obtained based on an expanding ratio of the display region, based on the change of the display region to the second display region being identified, while the cursor is being displayed using absolute coordinates wherein the absolute coordinates are obtained based on a reference line located on a side of the first flexible region.

10 . The operation method of claim 9 , further comprising:

based on using relative coordinates, determining coordinates of the cursor using the expanding ratio, wherein the expanding ratio is a ratio between a first length for the first flexible region and at least the portion of the second flexible region provided as the second display region and a second length for the first flexible region provided as the first display region.

11 . The operation method of claim 8 , further comprising:

moving the cursor within the first flexible region while the display region is changed to the second display region.

12 . The operation method of claim 8 , further comprising:

based on the change of the display region to the first display region being identified, while the cursor is being displayed using absolute coordinates,

moving the cursor to a random position of the first flexible region and outputting the moved cursor; or

moving the cursor to a designated portion of the first flexible region adjacent to the second flexible region and outputting the moved cursor.
