1. A mobile terminal, comprising:
- a touchscreen displaying a plurality of icons, the plurality of icons including a first icon corresponding to a first application requiring authentication to execute the first application and provided on a first region of the touchscreen, the touchscreen including;
a plurality of Tx lines in a touch sensing layer, wherein the plurality of Tx lines include a plurality of primary Tx lines and a plurality of subsidiary Tx lines, and the plurality of subsidiary Tx lines are provided between neighboring ones of the plurality of primary Tx lines;
a plurality of Rx lines intersecting the plurality of Tx lines in the touch sensing layer, wherein the plurality of Rx lines include a plurality of primary Rx lines and a plurality of subsidiary Rx lines, and the plurality of subsidiary Rx lines are provided between neighboring ones of the plurality of primary Rx lines,a first sensor formed at the touchscreen, the first sensor including the plurality of primary Tx lines and the plurality of primary Rx lines;
a second sensor formed at the touch screen, the second sensor including a first portion of the plurality of primary Tx lines and the plurality of subsidiary Tx lines provided between neighboring Tx lines of the first portion of the plurality of primary Tx lines, and a first portion of the plurality of primary Rx lines and the plurality of subsidiary Rx lines provided between neighboring Rx lines of the first portion of the plurality of primary Rx lines, wherein the second sensor is overlapping with the first region and is activated in response to a touch input received via the first sensor on the first region of the touchscreen; and
a controller configured to;
receive a touch input via the first sensor and activate the second sensor;
receive touch input signals via the second sensor and binarize the touch input signals to determine whether the touch input signals correspond to a finger touch input or a non-finger touch input;
receive first fingerprint information via the second sensor when the touch input signals are determined to correspond to a finger touch input and execute the first application when the first fingerprint information matches reference fingerprint information; and
control the touchscreen to display a prescribed user interface for authentication when the touch input signals are determined to correspond to a non-finger touch input.

Abstract
The present invention relates to a mobile terminal and a method for controlling the same. The present invention determines whether received touch input is touch input by a finger of a user and, when a function executed by the touch input requires authentication, provides a user interface necessary for authentication differently according to whether the touch input is touch input by the user'"'"'s finger. Accordingly, fingerprint authentication is processed as necessary, thereby improving processor efficiency.
