Method for detecting touch position of touch screen and touch screen using same

A touch screen comprising:

• a touch screen panel comprising a plurality of touch screen blocks including a plurality of touch sensors;
• a signal processing controller detecting a touch position on a touch screen block in which a touch is detected, among a plurality of touch screen blocks included in the touch screen panel;
• and
• a switch unit first transmitting at least one signal, among signals generated from the plurality of touch sensors included in the plurality of touch screen blocks, to the signal processing controller, and transmitting signals that are generated in the touch screen block in which the touch is detected to the signal processing controller on the basis of a response of the signal processing controller,
• wherein, if the touched touch screen block is detected by using signals generated from the plurality of touch sensors among touch sensors included in the touch screen blocks, the switch unit comprises:
• block switches adding the signals generated from the plurality of touch sensors among the touch sensors included in the touch screen blocks on each touch screen block in which the signals are generated;
• and
• channel switches operating in synchronization with the block switches and transmitting the signals added by the block switches to the signal processing controller.

• and
• a MUX unit adding at least two signals transmitted from the switch unit and transmitting the at least two added signals to the signal processing controller.
