  • Display device having touch screen panel that offsets induction voltage induced in common electrode
    Patent number: 8970517
    Abstract: A display device having a touch screen panel includes a display panel includes a common electrode; a touch screen panel including a plurality of first conductive patterns that are formed on one surface of the display panel and arranged in a first direction, and a plurality of second conductive patterns that are electrically insulated from the plurality of first conductive patterns and arranged in a second direction to cross over the first conductive patterns; a power source circuitry to supply a first common voltage to the common electrode and to supply a pulse voltage to at least one of the plurality of first and second conductive patterns; and a common voltage feedback circuit to remove an induction voltage induced to the common electrode by the pulse voltage supplied to the at least one of the plurality of first and second conductive patterns.
