    摘要: A touch substrate, a touch display panel, a touch display device, and a touch driving method are provided. The touch substrate includes: a base substrate, on which a touch electrode pattern is formed. The touch electrode pattern includes at least one electrode group, and each electrode group includes a driving electrode and a sensing electrode which are arranged in a row along a first direction of the base substrate and insulated from each other. In each electrode group, the driving electrode has a plurality of driving electrode portions coupled to each other, and the sensing electrode has a plurality of sensing electrode blocks. Each driving electrode portion is respectively between two adjacent sensing electrode blocks; and the sensing electrode block has a plurality of sensing electrode regions with different areas.

    摘要: The present disclosure provides a touch screen and a display device. The touch screen includes a substrate, and a first metal wiring layer, a second metal wiring layer, and a third metal wiring layer formed on the substrate. A first insulation layer is arranged on a surface of the first metal wiring layer, and the second metal wiring layer is arranged on the first insulation layer. A second insulation layer is arranged on a surface of the second metal wiring layer, and the third metal wiring layer is arranged on the second insulation layer. Electrical connection channels are electrically connected to the second electrode channels in a one-to-one corresponding manner by using through holes, and the electrical connection channels are electrically connected to a second electrode lead terminal, so that the second electrode channels are electrically connected to the second electrode lead terminal.
