Foldable device and method of controlling the same
A foldable device includes: a display; a touch panel configured to detect a touch input; a sensing interface configured to detect an angle of the foldable device; and a controller configured to activate the display unit when the angle detected by the sensing unit as the foldable device is unfolded is equal to or greater than a first angle, and activate the touch panel when the angle detected by the sensing unit is equal to or greater than a second angle.
1. An electronic device, the device comprising:
a flexible display;
a first sensor configured to detect bending of the electronic device;
a second sensor configured to detect biometric information of a user; and
a processor configured to determine that the bending corresponds to unfolding of the electronic device, authenticate the user based on the biometric information while the electronic device is unfolding, and control the electronic device to provide an unlocked screen on the flexible display in response to authenticating the user when the electronic device is unfolded.
2. The device as claimed in claim 1 , wherein the processor is further configured to determine that the electronic device is unfolded if an unfolded angle of the electronic device is greater than or equal to a predetermined first angle based on the bending sensed by the first sensor.
3. The device as claimed in claim 2 , wherein the second sensor is positioned on a bezel of the electronic device.
4. The device as claimed in claim 2 , wherein the second sensor comprises at least one of a fingerprint recognition sensor configured to sense fingerprint information of the user and an iris recognition sensor configured to sense iris information of the user.
5. The device as claimed in claim 2 , wherein the processor is further configured to determine the unfolded angle sensed being a second angle which is predetermined and less than the first angle, and to control the flexible display to provide a screen that indicates user authentication is in progress while the electronic device is unfolding, in response to determining the unfolded angle being the second angle.
6. The device as claimed in claim 5 , wherein the screen indicating that the user authentication is in progress comprises an image which changes in accordance with increase in the unfolded angle of the electronic device based on the bending sensed by the first sensor.
7. The device as claimed in claim 5 , wherein the screen indicating that the user authentication is in progress comprises an image corresponding to the biometric information required to authenticate the user.
8. The device as claimed in claim 1 , wherein the unlocked screen comprises a background, and
wherein processor is further configured to control the flexible display to provide a locked screen if the user is not authenticated, and the locked screen is one of a screen indicating that the authenticating is unsuccessful, a screen re-requesting user authentication, and a screen requesting input of a prestored password.
9. A method of unlocking an electronic device including a flexible display, the method comprising:
detecting bending of the electronic device;
detecting biometric information of a user;
determining that the bending corresponds to unfolding of the electronic device;
authenticating the user based on the biometric information while the electronic device is unfolding; and
providing an unlocked screen on the flexible display in response to authenticating the user when the electronic device is unfolded.
10. The method as claimed in claim 9 , wherein the determining that the bending corresponds to unfolding of the electronic device comprises, determining that the device is unfolded if an unfolded angle of the electronic device is greater than or equal to a predetermined first angle based on the bending.
11. The method as claimed in claim 10 , wherein the detecting biometric information comprises sensing the biometric information through a sensor positioned on a bezel of the electronic device.
12. The method as claimed in claim 10 , wherein the detecting biometric information comprises sensing the biometric information through at least one of a fingerprint recognition sensor configured to sense fingerprint information of the user and an iris recognition sensor configured to sense iris information of the user.
13. The method as claimed in claim 10 , further comprising:
determining the unfolded angle being a second angle which is predetermined and less than the first angle; and
providing a screen that indicates user authentication is in progress while the electronic device is unfolding, in response to determining the unfolded angle being the second angle.
14. The method as claimed in claim 13 , wherein the screen indicating that the user authentication is in progress comprises an image which changes in accordance with increase in the unfolded angle of the electronic device based on the bending.
15. The method as claimed in claim 13 , wherein the screen indicating that the user authentication is in progress comprises an image corresponding to the biometric information required to authenticate the user.
16. The method as claimed in claim 9 , wherein the unlock screen comprises a background, and
wherein the method further comprises providing a locked screen if the user is not authenticated by the authenticating, and the locked screen is one of a screen indicating that the authenticating is unsuccessful, a screen re-requesting user authentication, and a screen requesting input of a prestored password.
