  • Touch controller, touch sensing device, and touch sensing method
    Patent number: 11256365
    Abstract: A touch controller includes a controller receiving a display timing signal and generating a touch sensing control signal synchronously with the display timing signal. The touch controller also includes a sensing circuit driving a touch sensing array in response to the touch sensing control signal in order to generate touch data corresponding to sensing signals provided by the touch sensing array. The sensing circuit provides a first driving signal having a first polarity to at least one driving channel of the touch sensing array during a first display frame period, and provides a second driving signal having a second polarity different from the first polarity during a second display frame period.
