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: The invention relates to touch display device and display panel. Provided are a touch display device and a display panel able to improve touch sensing performance by reducing crosstalk occurring between data lines and touch lines. A shield pattern is disposed in an area in which the touch lines overlap the data lines.

Abstract: In a touch display panel (110) and a touch display device (100), a shielding pattern (SPTN) is arranged between a data link line (DLL) and a touch link line (TLL) in a non-active area (N/A; L/A) of the touch display panel, and a signal corresponding to the touch driving signal (TDS) is applied to the shielding pattern (SPTN). Parasitic capacitance (Cp) between the data link line (DLL) and the touch link line (TLL) is prevented in order to reduce noise on the touch sensing signal caused by voltage fluctuation on the data link line (DLL). Accordingly, it is possible to reduce the influence of display driving on touch sensing, thereby improving touch sensing during display driving.
