Description
technical field [0001] The present application relates to the field of display technology, in particular to a touch display panel, a touch display device and a driving method applied to the touch display panel. Background technique [0002] Touch screens are divided into self-capacitive touch screens and mutual-capacity touch screens according to their touch control principles. Existing mutual capacitive touch screens usually utilize touch driving electrodes and touch sensing electrodes to form a mutual capacitance, and detect touch points by measuring the change of charge in the mutual capacitance during touch. [0003] In the touch detection process of the above-mentioned mutual-capacitive touch display screen, it is necessary to send a touch driving signal to the touch driving electrode through an integrated circuit arranged on the touch display panel, and receive a touch detection signal transmitted by the touch detection electrode. to determine if there is a touch poin...
