Abstract: The present exemplary embodiments provide a touch display device which connects a touch driving circuit and a plurality of touch sensors using a plurality of dummy pixels disposed on a display panel to recognize touch event of a user. When the touch wiring line is implemented, the same material as the pixel electrode or the source line included in the plurality of dummy pixels is used so that a separate process for implementing the touch wiring line is not necessary. Further, in a pixel structure in which one data line is disposed for every two pixels, the source line is disposed in a region where the data line is not disposed to be used as a touch wiring line. Therefore, the touch recognizable area may expand as compared with a case using a pixel metal.

Abstract: A touch display device drives only some of a plurality of common electrodes disposed in a display panel as a touch electrode, so that an increase of lines and a reduction of an aperture ratio according to implementing a function of a touch sensing can be minimized, and as adjusting a total resistance and a resistance distribution according to locations between the common electrode driven as the touch electrode and the common electrode not driven as the touch electrode same or similarly, an abnormality of a display driving due to partial driving the plurality of common electrodes as the touch electrode and provide the function of the touch sensing can be prevented.
