Abstract
A touch display device accurately distinguishes a touch input performed using a finger and a touch input performed using a pen, such as a stylus, significantly reduce a touch sensing time, simultaneously perform a display operation and a touch sensing operation, and operate in a power saving manner. Touch sensing does not restrict an image display time of a display panel. Touch inputs are sensed without degradation in touch performance, which would otherwise be caused by parasitic capacitance occurring in electrodes within the display panel, such as data lines or gate lines.
