TOUCH SENSING UNIT, TOUCH SCREEN PANEL HAVING THE SAME, AND METHOD OF DRIVING THE TOUCH SCREEN PANEL

摘要

A touch screen panel and a driving method thereof. The touch screen panel includes a touch pad unit including a plurality of receiver pads and a plurality of transmitter pads combined with the receiver pads, and a touch sensing unit for determining a touch position, based on changes in mutual capacitance between the receiver pads and the transmitter pads. The touch sensing unit determines maximum values for every column by scanning touch sensing signals in the column direction of the touch pad unit, decides whether rows having maximum values for every column are the same, when the rows having the maximum values for every column are not the same, determines a greatest value by comparing all values of the scanned touch sensing signals, and determines touch coordinates through a combination of transmitter and receiver pads corresponding to the position at which the greatest value exists.
