Abstract
The present disclosure relates to a driving method and a driving device of touch display panels, and a touch display. The driving method includes: detecting a voltage potential of at least one pixel electrode within the areas of the touch display panel corresponding to different touch scanning partitions, negating the voltage potential, overlapping the negated voltage potential and feed-backed touch pulse signals, and adopting overlapped signals to be the detected touch pulse signals. With the configuration of the touch scanning partitions, the voltage potentials of the pixel electrodes within each of the areas are adopted to respectively adjust the feed-backed touch pulse signals such that the display scanning and the touch scanning can be conducted simultaneously. The detection precision of the touch pulse signals may be enhanced without affecting the display performance.
