Abstract: According to the present invention, a charging and discharging circuit is electrically connected to an operation signal line and a detection signal line, and repeats a charging and discharging operation of a node capacitor. The present invention also includes an integration capacitor electrically connected to the detection signal line and an integration circuit charging the integration capacitor to a unit charging voltage every charging and discharging operation of the node capacitor such that the integration capacitor is charged to a first voltage that is integrated according to a charging and discharging number. The integration circuit may include a reset switch electrically connected to the integration capacitor and discharging the first voltage integrated and charged to the integration capacitor for initializing.

Abstract: A touch sensor includes a plurality of operation patterns arranged in a first axis direction and supplied with a voltage, a dielectric material layer formed over the plurality of operation patterns, and a plurality of sense patterns formed over the dielectric material layer and arranged in a second axis direction to cross the first axis direction. At least one of the plurality of sense patterns has a parallel structure in which the sense pattern is separated into two or more lines, and the separated sense patterns are recombined once or more. A touch screen having a low resistance value can be obtained.
