    Abstract: A touch system includes a touch panel having first electrodes formed in a first direction, second electrodes formed in a second direction, and driving lines and pre-charge lines connected to respective first electrodes; and a touch IC unit configured to successively apply driving signals to the first electrodes, receive sensing signals through the second electrodes, and, when applying the driving signal to a driving line connected to a first electrode chosen as a driving electrode from the first electrodes, apply a pre-charge signal to a pre-charge line connected to at least one first electrode chosen as a pre-driving electrode from the other first electrodes than the first electrode chosen as the driving electrode.

    Abstract: A disclosed method for assigning a touch identification in a multi-touch sensitive display device is includes applying a touch driving signal to touch sensors of a touch screen and generating raw touch data, detecting touch points based on the raw touch data and respectively assigning temporary identifications (IDs) to the touch points, grouping the touch points based on a difference in distances between the touch points to form touch groups, and forming adaptive touch groups respectively based on the touch groups. The method also includes setting a comparison block including one or more of the adaptive touch groups contacting or overlapping each other, and matching the temporary ID assigned to one of the touch points within the comparison block in the current frame to one of a plurality of touch IDs within the comparison block in a previous frame.
