Abstract
Disclosed are touch display panel, method for driving touch display panel, and display device. The touch display panel includes display region including plurality of touch driver electrodes and plurality of touch sensing electrodes both arranged in array, and non-display region surrounding display region and including touch auxiliary circuit and touch driver circuit. When refresh frequency is first frequency, touch driver circuit configured to provide touch drive signal for each touch driver electrode in touch stage, and receive touch sensing signal returned by each touch sensing electrode to determine touch position according to touch sensing signal. When refresh frequency is the first frequency, touch auxiliary circuit configured to provide first voltage signal for each touch driver electrode in touch stage; and voltage of first voltage signal greater than voltage of touch drive signal. The present disclosure can increase report rate, and satisfy touch and display requirements for high refresh frequency.
