Abstract
There is provided a touch screen apparatus capable of detecting the presence a touch action and a position in a touch region depending on a change in electrical energy of one node of a touch sensor. A touch screen apparatus according to the present invention includes a plurality of pixels for displaying images and a plurality of touch sensors. Each of the plurality of touch sensors includes a first node being provided an electrical energy; a sensor capacitor for changing the electric potential energy of the first node depending on presence a touch action; a first switch for providing a sensing signal to the touch line controlled by the electrical energy of the first node; and a second switch for providing the electrical energy to the first node.
