ABSTRACT:
A display device includes a plurality of first and second sensing data lines; a plurality of first and second sensors connected to the first and second sensing data lines, respectively; a plurality of first signal converters which compare a first sensing data signal with a first reference voltage and output a first sensing output signal; a plurality of second signal converters which compare a second sensing data signal with the first reference voltage and output a second sensing output signal; a first position signal output unit which outputs a predetermined bit of a first position signal; a second position signal output unit which outputs a predetermined bit of a second position signal; a signal output unit which outputs a digital sensing signal in series; and a contact determiner which determines a contact position of the first and second sensors.
