Abstract
Provided are a touch display substrate, an electronic device and a driving method. The touch display substrate includes a common electrode layer and a wire layer arranged opposite to each other. The common electrode layer includes multiple common electrodes arranged in an array. The wire layer includes multiple wires connected to the common electrodes in a one-to-one way. The wires do not intersect with one another and are for inputting touch detection signals to the common electrodes, the wires extend in the same direction and touch detection signals are input to the wires simultaneously, and a phase difference between touch detection signals for at least two adjacent wires is 180 degrees. Interferences on one common electrode from the two wires, for which the touch detection signals have a phase difference of 180 degrees, may cancel each other out, thereby attenuating vertical crosstalk and improving the accuracy of touch detection.
