Abstract
A foldable device including a first body supporting a first display region; a second body supporting a second display region; a sensor configured to sense a folding angle between the first body and the second body; an actuator configured to change the folding angle; and a controller configured to control the actuator to increase the folding angle between the first body and the second body without user physical pressure in response to a first predetermined input, and control the actuator unit to decrease the folding angle between the first body and the second body without user physical pressure in response to a second predetermined input.
Claims16
A foldable device, comprising:
- a first body supporting a first display region;
- a second body supporting a second display region;
- a sensor configured to sense a folding angle between the first body and the second body;
- an actuator configured to change the folding angle, the actuator comprising at least one of an electromagnet and a shape memory alloy;
- and
- a controller configured to:
- control the actuator to increase the folding angle between the first body and the second body without user physical pressure in response to a first predetermined input, and
- control the actuator to decrease the folding angle between the first body and the second body without user physical pressure in response to a second predetermined input,
- wherein the controller is further configured to:
- when the foldable device is switched from an opened state to a closed state and the folding angle is equal to or smaller than a first angle, control the actuator to change a switching speed by switching a magnetism of at least one preset region of the first body and the second body, and
- wherein if an event occurs in the closed state of the foldable device, the controller is further configured to determine the switching speed to the opened state of the foldable device based on a type of the occurring event.
A method of controlling a foldable device including a first body supporting a first display region, and a second body supporting a second display region, the method comprising:
- sensing, via a sensor of the foldable device, a folding angle between the first body and the second body;
- controlling, via a controller, an actuator of the foldable device to increase the folding angle between the first body and the second body without user physical pressure in response to a first predetermined input, the actuator comprising at least one of an electromagnet and a shape memory alloy;
- and
- controlling, via the controller, the actuator to decrease the folding angle between the first body and the second body without user physical pressure in response to a second predetermined input,
- wherein the method further comprises:
- when the foldable device is switched from an opened state to a closed state and the folding angle is equal to or smaller than a first angle, controlling the actuator to change a switching speed by switching a magnetism of at least one preset region of the first body and the second body;
- and
- if an event occurs in the closed state of the foldable device, determining the switching speed to the opened state of the foldable device based on a type of the occurring event.
