Slidable electronic device and control method thereof

An electronic device comprising:

• a housing;
• a flexible display at least a part of which is viewable to the outside;
• at least one processor operatively connected to the flexible display;
• and
• a communication module comprising communication circuitry,
• wherein the at least one processor is configured to:
• in a state where a first portion of the flexible display is viewable to the outside, based on a first user input for a sliding operation for exposing to be viewable a second portion of the flexible display comprising at least a part of the first portion of the flexible display being received via the flexible display, display, on the at least a part of the first portion, an object for receiving a user input for performing at least one function,
• receive a second user input via an area in which the object is displayed,
• based on the second user input being received, slide at least one area of the flexible display to expose to be viewable the second portion of the flexible display,
• display, on at least a part of the second portion, at least one screen on which at least one function corresponding to the second user input is to be performed, and
• transmit, through the communication module, a command for a sliding operation of a display included in an external electronic device and information related to at least one screen to the external electronic device so that the at least one screen on which at least one function corresponding to the second user input is to be performed can be displayed on the display included in the external electronic device.

A control method of an electronic device, the control method comprising:

• in a state where a first portion of a flexible display is viewable to the outside, based on a first user input for a sliding operation for exposing to be viewable a second portion comprising at least a part of the first portion of the flexible display to the outside being received through the flexible display, displaying, on the at least a part of the first portion, an object for receiving a user input for performing at least one function, wherein the object is displayed to overlap content displayed in the first portion and a function related to the overlapped content is deactivated;
• receiving a second user input through an area in which the object is displayed;
• based on the second user input being received, sliding at least one area of the flexible display to expose the second portion of the flexible display to be viewable to the outside;
• and
• displaying, on at least a part of the second portion, at least one screen on which at least one function corresponding to the second user input is performed.
