Abstract
Disclosed is a timing controller for a display panel comprising: a mode controller arranged to operate a display panel in one of a sensing mode or a display mode; a sensing controller arranged to obtain sensed data associated with a transistor during the sensing mode, the transistor corresponding to a touch recognition area of the display panel; a touch controller arranged to compare a change value of the sensed data with a touch critical range; wherein the touch controller is further arranged to extract position information or identification information on the touch recognition area if the change value is within the touch critical range.
