Abstract

The invention discloses a touch display panel and a driving method thereof. The touch display panel comprises a substrate, a plurality of touch display units and a gate driving circuit, wherein the substrate comprises a display region and a frame region; the touch display units are arranged in the display region; each touch display unit comprises a plurality of gate lines and a plurality of electrode blocks; the gate lines extend along the first direction; the electrode blocks are arrayed along the first direction; the electrode blocks are opposite to the gate lines in the direction perpendicular to the substrate; and the gate driving circuit is arranged in the frame region and is electrically connected with the gate lines. In a display driving schedule section, the gate driving circuit is used for scanning the various gate lines, the scanned adjacent optional two gate lines are positioned in the different touch display units, starting signals of the scanned adjacent optional two gate lines are partially overlapped, and starting signals of the gate lines in the same touch display unit are not overlapped. By the touch display panel and the driving method thereof, the problem that displaying cross grains exist on a junction is avoided.

Description

technical field [0001] The present invention relates to the technical field of touch display, and more specifically, to a touch display panel and a driving method thereof. Background technique [0002] In the initial stage of the development of the touch display, the touch display panel is formed by laminating the touch panel and the display panel to realize the touch display. The touch panel and the display panel need to be prepared separately, the cost is high, the thickness is relatively large, and the production efficiency is low. [0003] With the development of touch display integration technology, the common electrode of the touch display panel of the display panel can also be used as the touch sensing electrode for touch detection, and the touch control and display control can be performed in time-sequence through time-sharing driving, and can be simultaneously Realize touch and display functions. In this way, the touch sensing electrodes are directly integrated in...
