Abstract: Provided are a touch sensor embedded display device and a method for driving the same. A method includes: sequentially, in the display period: performing a display scan of a first area of the display panel based on one display line; and applying data of an input image to the pixels of the first area; simultaneously performing: a touch scan of a first touch line of the display panel and a touch scan of a second touch line of the display panel in a touch period following the display period; and simultaneously sensing touch inputs of the touch sensors on the first and second touch lines in the touch period, wherein each of the first and second touch lines overlaps a plurality of display lines, and wherein a width of each of the first and second touch lines is greater than a width of each of the plurality of display lines.

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.
