Foldable device and method of controlling the same

A method of controlling a foldable device comprising a hinge for folding or unfolding the foldable device, wherein the foldable device is divided into a first body part and a second body part by the hinge, a sensor for detecting whether the foldable device is folded, wherein the sensor is arranged in a folded region corresponding to the hinge, a first display disposed on a first surface of the foldable device while the foldable device is unfolded, wherein the first display is deformable according to the folding between the first body part and the second body part of the foldable device by the hinge, and a second display disposed on a second surface of the foldable device while the foldable device is unfolded, wherein the second display is disposed on the first body part of the foldable device and the second surface is opposite of the first surface, the method comprising:

• in an unfolded state, controlling the first display to display a first execution screen of a first application in a first size corresponding to an area of the first display;
• based on a first notification event related to a second application, different from the first application, being detected while the first execution screen of the first application is displayed on the first display in the unfolded state, control the first display to display first information related to the first notification event together with the first execution screen of the first application;
• and
• based on a first folded state in which the foldable device is folded such that a visible part of the first display and the second display are disposed in a same direction while the first information is displayed together with the first execution screen of the first application on the first display, controlling the first display to display the first information and the first execution screen of the first application in a second size corresponding to the visible part of the first display and the second display to display a second execution screen of the second application related to the first notification event,
• wherein the method further comprises, based on the sensor detecting that the foldable device is folded such that a visible part of the first display and the second display are disposed in the same direction:
• determining whether a notification event has occurred such that notification event information relating to one or more predetermined applications, including the second application, is displayed together with the first execution screen of the first application on the first display;
• and
• based on determining that the notification event has not occurred, determining according to a predetermined setting a screen to display on the second display and control the first display to display the first execution screen of the first application in the second size corresponding to the visible part of the first display and the second display to display the determined screen.

A foldable device comprising:

• a hinge for folding or unfolding the foldable device, wherein the foldable device is divided into a first body part and a second body part by the hinge;
• a sensor for detecting whether the foldable device is folded, wherein the sensor is arranged in a folded region corresponding to hinge;
• a first display disposed on a first surface of the foldable device while the foldable device is unfolded, wherein the first display is deformable according to the folding between the first body part and the second body part of the foldable device by the hinge;
• a second display disposed on a second surface of the foldable device while the foldable device is unfolded, wherein the second display is disposed on the first body part of the foldable device and the second surface is opposite of the first surface;
• a sensor configured to detect a folding state of the folding or the unfolding of the foldable device;
• and
• a controller configured to:
• in an unfolded state, control the first display to display a first execution screen of a first application in a first size corresponding to an area of the first display,
• based on a first notification event related to a second application, different from the first application, being detected while the first execution screen of the first application is displayed on the first display in the unfolded state, control the first display to display first information related to the first notification event together with the first execution screen of the first application, and
• based on a first folded state in which the foldable device is folded such that a visible part of the first display and the second display are disposed in a same direction while the first information is displayed together with the first execution screen of the first application on the first display, control the first display to display the first information and the first execution screen of the first application in a second size corresponding to the visible part of the first display and the second display to display a second execution screen of the second application related to the first notification event,
• wherein the controller is further configured to, based on the sensor detecting that the foldable device is folded such that a visible part of the first display and the second display are disposed in the same direction:
• determine whether a notification event has occurred such that notification event information relating to one or more predetermined applications, including the second application, is displayed together with the first execution screen of the first application on the first display;
• and
• based on determining that the notification event has not occurred, determine according to a predetermined setting a screen to display on the second display and control the first display to display the first execution screen of the first application in the second size corresponding to the visible part of the first display and the second display to display the determined screen.
