Abstract

A display device and a method for controlling the same are disclosed. The display device comprises an input unit configured to receive a command for generating an event and a fingerprint; a control unit configured to generate the event in accordance with the command and process the generated event; and a display unit configured to display a user menu, wherein the input unit includes a touch recognition layer for recognizing a touch input and a fingerprint recognition layer for recognizing a fingerprint, the touch recognition layer and the fingerprint recognition layer being formed in a single body with the display unit and receiving a command for generating an event of a temporary unlock fingerprint setting mode and a first fingerprint different from a registered fingerprint, the control unit implements the temporary unlock fingerprint setting mode in accordance with the command for generating the input event, sets the input first fingerprint to a temporary unlock fingerprint, and unlocks the display device if the temporary unlock fingerprint is input thereto, and the temporary unlock fingerprint is released in accordance with a predetermined condition.

Claims

1. A display device comprising:

a storage unit;

an input unit configured to receive a command for generating an event and to receive a fingerprint;

a control unit configured to generate the event in accordance with the command and process the generated event; and

a display unit configured to display a user menu,

wherein the input unit includes a touch recognition layer for recognizing a touch input and a fingerprint recognition layer for recognizing a fingerprint, the touch recognition layer and the fingerprint recognition layer being formed in a single body with the display unit and receiving a command for generating an event for a temporary unlock fingerprint setting mode and a first fingerprint different from a registered fingerprint for master unlock,

wherein the storage unit is configured to store a second fingerprint different from the registered fingerprint for master unlock,

wherein the control unit is further configured to;

implement the temporary unlock fingerprint setting mode in accordance with the command for generating the input event,

set the input of the first fingerprint to a temporary unlock fingerprint,

unlock the display device when the temporary unlock fingerprint is inputted,

release the temporary unlock fingerprint in accordance with a predetermined condition, and

give an unlock power to the released temporary unlock fingerprint within a predetermined time if the second fingerprint is inputted.

2. The display device according to claim 1, wherein the control unit recognizes the command for generating an event for a temporary unlock fingerprint setting mode when the registered fingerprint is inputted for a predetermined time or more.

3. The display device according to claim 2, wherein the input unit receives the registered fingerprint when the display unit is turned off.

4. The display device according to claim 1, wherein the control unit recognizes the command for generating an event for a temporary unlock fingerprint setting mode when the registered fingerprint and the first fingerprint are inputted together.

5. The display device according to claim 1, further comprising a storage unit configured to store a third fingerprint for generating an event for the temporary unlock fingerprint setting mode, the third fingerprint being different from a fingerprint for master unlock, wherein the control unit recognizes the command for generating an event for a temporary unlock fingerprint setting mode when the third fingerprint is inputted.

6. The display device according to claim 1, wherein the control unit recognizes the command for generating an event for a temporary unlock fingerprint setting mode when a predetermined area is touched for a predetermined time or more.

7. The display device according to claim 1, wherein the control unit recognizes the command for generating an event for a temporary unlock fingerprint setting mode when a predetermined screen is outputted to the display unit and a predetermined area of the output screen is touched.

8. The display device according to claim 1, wherein the control unit recognizes the command for generating an event for a temporary unlock fingerprint setting mode when at least one of a predetermined first touch pattern and a first knock-on pattern is inputted.

9. The display device according to claim 8, wherein the display unit is turned off.

10. The display device according to claim 1, wherein the input unit includes a function key, and the control unit recognizes the command for generating an event for a temporary unlock fingerprint setting mode when the user command is inputted through the function key.

11. The display device according to claim 1, wherein the control unit controls the display unit to display a fingerprint input guide for inputting the first fingerprint when the temporary unlock fingerprint setting mode is implemented.

12. The display device according to claim 11, wherein the fingerprint input guide includes at least one of a fingerprint input window, a fingerprint input area display, and a fingerprint input position display.

13. The display device according to claim 1, wherein the predetermined condition is a condition for initially inputting the registered fingerprint after the temporary unlock fingerprint is set.

14. The display device according to claim 1, wherein the predetermined condition is a condition for inputting at least one of a predetermined second touch pattern and a predetermined second knock-on pattern.

15. The display device according to claim 1, wherein the temporary unlock fingerprint includes valid time limit attributes, and the predetermined condition is a condition for expiring a predetermined valid time.

16. The display device according to claim 1, wherein the temporary unlock fingerprint includes limit attributes for a number of unlock times, and the predetermined condition is a condition that the number of unlock times is a predetermined number of unlock times.

17. The display device according to claim 1, wherein the control unit controls the display unit to output a message asking whether the temporary unlock fingerprint is released, when there is no input of the temporary unlock fingerprint for a predetermined time.

18. The display device according to claim 1, wherein the display unit outputs a release alarm message of the temporary unlock fingerprint.

19. A method for controlling a display device, the method comprising:

receiving a command for generating an event for a temporary unlock fingerprint setting mode;

implementing the temporary unlock fingerprint setting mode in accordance with the command for generating the event for the temporary unlock fingerprint setting mode;

receiving a first fingerprint different from a registered fingerprint for master unlock;

setting the first fingerprint to a temporary unlock fingerprint;

unlocking the display device when the temporary unlock fingerprint is inputted;

releasing the temporary unlock fingerprint in accordance with a predetermined condition; and

giving an unlock power to the released temporary unlock fingerprint within a predetermined time if a second fingerprint is inputted,

wherein the second fingerprint is stored at a storage unit and differs from the registered fingerprint for master unlock.
