Touch display device, touch display panel and driving method thereof

The invention provides a touch display device, a touch display panel and a driving method thereof. The touch display panel comprises a display area and a non-display area. The non-display area is provided with a driving chip, and the driving chip comprises a plurality of first pins, wherein at least part of the first pins output data driving signals to the display area at a display period and output touch signals to the display area at a touch period. Thus, it can be known that the same first pin can provide the data driving signals for a data line and can also provide the touch signals for a touch lead; therefore, the number of the pin of the driving chip can be reduced, and the dimension and cost of the driving chip can be reduced. The number of wires of the non-display area corresponding to first pins S1 can be reduced, the transmittance of the non-display area is improved, and curing incompletion of frame sealing glue located on the non-display area during the manufacture of the touch display panel is avoided.
