Touch Sensor, Its Driving Method And Display Device Using The Same

摘要

PURPOSE: A touch sensor, a driving method thereof and a display device using the same are provided to determine the occurrence of touch based on the variation of an integrated value by integrating an n-1-th voltage value with an n-th voltage value for this hour. CONSTITUTION: A display panel(100) displays an image. A touch panel(140) senses touch. A gate driving unit(130) applies a scan pulse to a gate line. A data driving unit(120) applies digital video data to a data line. A timing controller(110) controls the data driving unit and the gate driving unit. A touch signal controller(160) processes the output signal of the touch panel. A touch position detector(170) detects the touch position of the touch panel.
