    Abstract: A touch display panel and a touch display device. A shield electrode is disposed between a display electrode and touch electrodes, is driven using a signal corresponding to a signal applied to the touch electrodes. Display noise is blocked using the shield electrode, so that the sensitivity of touch sensing signals received from the touch electrodes are improved. In addition, due to the improved sensitivity of touch sensing signals, the performance of touch sensing based on a change in the self-capacitance of the touch electrodes is improved. Both a touch sensing function based on a change in the self-capacitance of the touch electrodes and a touch sensing function based on a change in the mutual capacitance of the touch electrodes are provided.

    Abstract: A touch display device, a data driving circuit (DDC), and a driving method are provided. The touch display device, the data driving circuit (DDC), and the driving method convert an image digital signal into an image analog signal in response to a gamma reference voltage (EGBI_M) which is applied to the touch electrodes (TE) arranged in the display panel (DISP) and which is modulated in synchronization with a first touch electrode driving signal (TDS1) swinging with a first amplitude (AMP1) and output a data signal (Vdata) corresponding to the image analog signal to the data lines (DL). Accordingly, it is possible to effectively simultaneously perform display and touch sensing.
