Flexible device and interfacing method thereof

1. A foldable device comprising:

a flexible display;

a hinge for folding or unfolding the foldable device, wherein the flexible display is divided into a first part and a second part by a folding line corresponding to the hinge;

a sensor configured to sense a folding angle between the first part of the flexible display and the second part of the flexible display while the foldable device is being unfolded; and

a processor configured to execute instructions to at least:

in response to identifying the folding angle between the first part of the flexible display and the second part of the flexible display being greater than a first threshold while the foldable device is being unfolded, control to provide content on the flexible display; and

in response to identifying an increase in the folding angle between the first part of the flexible display and the second part of the flexible display as the foldable device is being further unfolded in a state where the content is provided on the flexible display, control to change the content with reference to the folding line according to the folding angle.

2. The foldable device of claim 1 , wherein the sensor is configured to sense the folding angle while the foldable device is being unfolded by sensing an unfolding angle of the foldable device or by sensing an unfolding curvature of the foldable device.

3. The foldable device of claim 2 , wherein the processor is further configured to:

determine a variable component of content provided on the flexible display corresponding to the unfolding angle or the unfolding curvature, and

control the flexible display dynamically vary the content provided on the flexible display according to the variable component.

4. The foldable device of claim 2 , wherein the processor is further configured to:

dynamically vary the content provided on the flexible display by adjusting an arrangement of pixels allotted to an activation area corresponding to the unfolding angle or the unfolding curvature, and

control the flexible display to display the content provided on the flexible display resulting from the adjusting the arrangement of pixels in the activation area.

5. The foldable device of claim 1 , wherein the processor is further configured to:

dynamically vary the content provided on the flexible display corresponding to each of unfolding angles or each of unfolding curvatures of the foldable device, and

control the flexible display to sequentially vary the content provided on the flexible display corresponding to each of the unfolding angles or each of the unfolding curvatures.

6. The foldable device of claim 1 , wherein the processor is further configured to control the flexible display to start displaying the content provided on the flexible display in at least one of a folding axis of a screen of the flexible display, an edge of the screen of the flexible display, and a position on the screen of the flexible display.

7. The foldable device of claim 1 , wherein the content corresponds to a shortcut to execute at least one of an application installed on the foldable device, content stored in the foldable device, and a menu of the application.

8. The foldable device of claim 1 , wherein the processor is further configured to control the flexible display to display the content provided on the flexible display in which at least one of an arrangement of the content provided on the flexible display, an appearance of the content provided on the flexible display, and a number of the content provided on the flexible display, dynamically varies corresponding to the folding angle while the foldable device is being unfolded.

9. The foldable device of claim 8 , wherein the content comprises a plurality of objects, and

wherein the processor is further configured to control the flexible display such that at least one of an arrangement of the plurality of objects, an appearance of the plurality of objects, and a number of the plurality of objects, dynamically varies for each of a plurality of unfolding angles sensed by the sensor or for each of a plurality of unfolding curvatures sensed by the sensor.

10. The foldable device of claim 8 , wherein the content comprises only one object, and

wherein the processor is further configured to control the display of the one object such that an appearance of the one object dynamically varies for each of a plurality of unfolding angles sensed by the sensor or for each of a plurality of unfolding curvatures sensed by the sensor.

11. The foldable device of claim 1 , wherein the processor is configured to control the flexible display to increases a size of the content symmetrically with reference to the folding line according to the folding angle.
