TOUCH SENSOR IC, APPARATUS FOR SENSING TOUCH AND METHOD FOR COMPENSATING A TOUCH COORDINATE OF THE SAME

摘要

A touch sensing device according to the present invention includes a sensing area including a plurality of sensing nodes and a touch sensor chip which acquires a sensing signal for each of the sensing nodes and the respective coordinates of the sensing nodes in response to a touch input occurring in the touch area. The touch sensor chip can calculate corrected coordinates corresponding to the touch input based on the sensing signals.
