  • Patent number: 8988385
    Abstract: Disclosed are a touch panel driving apparatus and a display device including the same, which lead to the enhancement of sensing sensitivity. The touch panel driving apparatus includes a touch control unit and a touch sensing unit. The touch sensing unit is connected to the receiving lines, and generates the digital touch information on the basis of change of a capacitance between two transmitting lines and one receiving line or generates the digital touch information on the basis of change of a capacitance of each of the receiving lines to supply the digital touch information to the touch control unit, according to the sensing control signal.
