Abstract
Disclosed are a driving method for a touch display panel, and a touch display apparatus. The driving method for a touch display panel includes: providing a sinusoidal signal y for each electrode block in a common electrode within a display period, wherein the display period includes N display stages, each display stage has M image frames, the refresh rate of the display period is greater than or equal to a refresh rate threshold value A, N≥2, M≤1, N is a positive integer, M is a positive number, and the refresh rate threshold value A is the maximum refresh rate that can be identified by human eyes; providing a data signal for multiple pixel electrodes; and an electric field, formed by the pixel electrodes and the common electrode, driving the inversion of liquid crystal molecules in a liquid crystal layer.
