Abstract:
A touch screen device includes a touch pad including driving lines and sensing lines intersecting the driving lines, a driver configured to apply a driving signal to the driving lines, a signal output collector configured to receive a touch signal from the sensing lines, and a controller configured to control the driver and the signal output collector. The controller is further configured to control the driver to perform primary scanning to sequentially apply the driving signal to first driving lines disposed at predetermined intervals, among the driving lines, determine a scanning region, based on a first driving line where a touch is sensed among the first driving lines to which the driving signal is applied, and control the driver to perform secondary scanning to sequentially apply the driving signal to second driving lines included in the determined scanning region, among the driving lines.
