Abstract:
An array substrate having an embedded touch structure is disclosed. A common electrode layer is divided in to multiple first and second electrodes. Multiple first and second electrode connecting lines disposed in a touch wiring layer are respectively connected the first and second electrodes to a driving integrated chip one by one. A common voltage signal line, a first switching signal line and a first and second switches are disposed in a layout area. In a display sequence, the first switching signal controls the first and second switches to turn on, so the first and second electrode connecting lines are respectively connected to the common voltage signal line. In a touch sequence, the first switching signal controls the first and second switches to turn off to disconnect the first and second electrode connecting lines and the common voltage signal line. A display panel having the array substrate is also disclosed.
