Abstract
An electronic device includes a touch screen configured to display screen information and receive a touch input; a touch sensing module including a first sensing layer having a plurality of first electrode lines and a second sensing layer having a plurality of second electrode lines extending in a direction intersecting the first electrode lines; a plurality of first and second switches configured to selectively connect the plurality of first and second electrode lines to a circuit board; and a controller configured to in response to the received touch input having a touch pressure below a predetermined pressure, control the first switches to connect respective first electrode lines corresponding to a touch area of the touch input, and execute a first function corresponding the received touch input, in response to the received touch input having the touch pressure equal to or above the predetermined pressure, control the second switches to connect respective first and second electrode lines corresponding to the touch area of the touch input to change a first sensing resolution of the touch area to a second sensing resolution higher than the first sensing resolution, and obtain fingerprint information of a finger making contact with the touch area, and execute a second function more secure than the first function based on the obtained fingerprint information matching prestored fingerprint information.
