Fingerprint recognition touch sensor and electronic apparatus including the same

A touch sensor comprising:

• a plurality of parallel transmitting lines extending in a first direction;
• a plurality of parallel receiving lines extending in a second direction crossing the first direction;
• a transmitting driver configured to:
• in a fingerprint recognition mode, apply first driving signals of a first voltage, to the plurality of transmitting lines;
• in a low resolution touch sensing mode, apply second driving signals of a second voltage, to the plurality of transmitting lines, the second voltage being different than the first voltage;
• and
• in a high resolution touch sensing mode, apply third driving signals of a third voltage, to the plurality of transmitting lines, the third voltage being lower than the first voltage and higher than the second voltage;
• and
• a signal output unit configured to receive touch signals from the plurality of receiving lines.
