## Abstract

An electronic device according to an embodiment of the present invention may include: a flexible display; a bending sensing unit configured to sense a first bending and a second bending of the flexible display; and a control unit configured to execute a first function based on a first sensing result of the first bending from the bending sensing unit, and execute a second function based on a second sensing result of the second bending from the bending sensing unit, in which, when the first bending and the second bending correspond to a first predetermined condition, the control unit executes a third function based on the first bending and the second bending sensed by the bending sensing unit.

## Claims

### Claim 1

An electronic device comprising:
a flexible display;
one or more bending sensors coupled to the flexible display and configured to generate signals in response to a first bending at a first portion of the flexible display and a second bending at a second portion of the flexible display; and
a controller connected to the one or more bending sensors and comprising at least one processor to process the signals for controlling operation of the electronic device,
wherein the controller is configured to activate a first function of the electronic device when the first bending is sensed and reaches a first predetermined bending state for activating the first function and the controller is further configured to activate a second function of the electronic device when the second bending is sensed and reaches a second predetermined bending state for activating the second function,
wherein, in response to the second bending sensed while the first bending is occurring, the controller is configured to:
activate a third function different from the first and second functions while not activating the first and second functions, when (1) the second bending is sensed before the first function is activated and (2) the first bending and the second bending satisfy a predetermined condition, and
activate the first function, when (3) the second bending is sensed before the first function is activated and (4) the second bending is released while the first bending is still occurring, activate the first function.

### Claim 2 (depends on 1)

The electronic device of claim 1, wherein the first function comprises a first operation to set a function on the electronic device to which the flexible display is applied, the second function comprises a second operation to adjust the function and the third function comprises a third operation to reset the function.

### Claim 8 (depends on 7)

The electronic device of claim 7, wherein the first operation comprises a scroll up operation of a screen of the flexible display, the second operation comprises scroll down operation of the screen and the third operation comprises resetting the screen.

### Claim 9 (depends on 7)

The electronic device of claim 7, wherein each of the first function, the second function and the third function further comprises at least one of content conversion, page changing, bookmarking, scroll, screen capture, web browser conversion, web browser closing, volume adjustment, recording, rewinding, fast forwarding, setting sound source, focus adjustment, mode conversion, selecting an application, activating an application, rotating a screen, or screen locking.
