TOUCH SENSING APPARATUS AND DRIVING METHOD THEREOF

摘要

The present invention relates a touch sensing device and a driving method thereof comprising touch sensors arranged between Tx lines and Rx lines wherein the RX lines cross the Tx lines; a touch screen driving circuit generating touch raw data by driving the touch sensors through supplying a Tx driving signal to the Tx lines and by sensing the electrical signal of the touch sensors through the Rx lines; a touch recognition processor transmitting the coordinate information of a touch input position to the frequency of a touch report rate by analyzing the touch raw data. The touch report rate is faster than a display frame rate for updating data to every pixel in the display panel.
