1. A display device comprising:

  • a plurality of first sensing data lines extending in a first direction;

    a plurality of second sensing data lines extending in a second direction;

    a plurality of first sensors connected to the first sensing data lines;

    a plurality of second sensors connected to the second sensing data lines;

    a plurality of first signal converters which compare first sensing data signals from each of the first sensing data lines with a first reference voltage and output first sensing output signals;

    a plurality of second signal converters which compare second sensing data signals from each of the second sensing data lines with the first reference voltage and output second sensing output signals;

    a first position signal output unit which outputs a predetermined bit of a first position signal depending on the plurality of first sensing output signals;

    a second position signal output unit which outputs a predetermined bit of a second position signal depending on the plurality of second sensing output signals;

    a signal output unit which outputs a digital sensing signal in series based on the first and second position signals from the first and second position signal output units; and

    a contact determiner which determines a contact position of the first and second sensors based on the digital sensing signal from the signal output unit.
