Description

technical field [0001] The present invention relates to the field of display technology, in particular to a touch display panel, a driving method thereof, and a detection method of a sensing signal. Background technique [0002] With the continuous development of display technology, the application of touch screen has become more and more extensive. According to different working principles, touch screens are generally divided into: resistive touch screen, capacitive touch screen and infrared touch screen, etc.; The touch screen generally includes touch driving electrodes and touch sensing electrodes. When the driving signal is input to the touch driving electrodes, the voltage signal coupled by the touch sensing electrodes through the inductive capacitance is correspondingly detected. In this process, when a human body touches the When the capacitive touch screen is used, the electric field of the human body will act on the sensing capacitor, causing the capacitance of the ...
