TOUCH DISPLAY SUBSTRATE, ELECTRONIC DEVICE AND DRIVING METHOD

摘要

Provided is a touch display substrate, an electronic device and a driving method. The touch display substrate includes a substrate, and a common electrode layer and a wire layer arranged on a same side of the substrate. The common electrode layer includes multiple common electrodes. The wire layer includes multiple wires connected to the common electrodes respectively. The wire includes a first connection portion and a second connection portion. The common electrode is connected to a control circuit with the first connection portion and the second connection portion. A first end of the first connection portion is connected to the common electrode and a second end of the first connection portion is connected to a first end of the second connection portion. The second connection portion is parallel to a column direction of an array. The second end of the second connection portion is connected to the control circuit.
