Abstract
A touch display panel capable of operating in a display mode and a touch mode. In the touch mode, a data line transmits a data voltage signal to a pixel electrode of the touch display panel, and a corresponding common electrode is at a constant voltage level. In the touch mode, the data line transmits a touch driving signal to the pixel electrode and then receives a touch sensing signal from the pixel electrode, and the corresponding common electrode is floating.
