Abstract

A display device includes a display unit configured to display an image and to sense a touch input; a sensor unit configured to sense a fingerprint from the touch input; a storage unit configured to store data; and a processor configured to control the display unit, the sensor unit, and the storage unit, wherein the processor is further configured to: detect a selection input for selecting first information, the first information having a security on state or a security off state; obtain the fingerprint from the selection input, and convert the first information from the security on state into the security off state when the obtained fingerprint is matched with a pre-stored fingerprint; and when a predetermined was detected before the first information is converted into the security off state, maintain the first information to the security on state by not obtaining the fingerprint from the selection input.

Dependent claims

A display device comprising:

a display unit configured to display an image and to sense a touch input;
a sensor unit configured to sense a fingerprint from the touch input on the display unit;
a storage unit configured to store data;
and
a processor configured to control the display unit, the sensor unit, and the storage unit,
wherein the processor is further configured to:
detect a selection input for selecting a first information in a security on state;
obtain the fingerprint from the selection input;
when a predetermined input for the first information is not detected and the obtained fingerprint is matched with a pre-stored fingerprint, convert the first information from the security on state into a security off state;
and
when the predetermined input for the first information is detected before the first information is converted into the security off state, maintain the first information to the security on state and output a second information even if the obtained fingerprint is matched with the pre-stored fingerprint, and
wherein the predetermined input is one of a press input on physical button of the display unit, a voice input inputted on the display device, a gesture input inputted on the display device or a predetermined touch input inputted on the display unit.
