  • Publication number: 20120242597
    Abstract: A display with integrated touch sensor and a driving method thereof are provided. The display comprises a display data driving circuit that supplies analog video data voltages to data lines of a display panel during a display period and maintains the voltage of the data lines at the same specific DC voltage during a touch sensor driving period; a display scan driving circuit that sequentially supplies scan pulses synchronized with the analog video data voltages to the gate lines of the display panel during the display period; a touch sensor driving circuit that sequentially supplies driving pulses to the Tx lines of the display panel during the touch sensor driving period; and a touch sensor readout circuit that receives a touch signal from the mutual capacitances via the Rx lines of the display panel during the touch sensor driving period.
