Title: EMBEDDED TOUCH PANEL AND ARRAY SUBSTRATE THEREOF
Abstract:
An array substrate of an embedded touch panel, the array substrate comprising: touch electrodes (200), arranged in an active region of a touch panel in the form of an array; touch sensing chips (IC), arranged outside of the active region of the touch panel; and metal connecting lines (ML), which are arranged on different layers than the touch electrodes (200), are connected to the touch electrodes (200) by means of holes (H) and are stacked with data lines (DL) of the touch panel in a mutually insulating manner, wherein the touch electrodes (200) are connected to the touch sensing chips (IC) by means of the metal connecting lines (ML); a switching circuit is arranged between the metal connecting lines (ML) and the data lines (DL), and the switching circuit is used for connecting the metal connecting lines (ML) and the data lines (DL) at a touch phase and disconnecting the metal connecting lines (ML) and the data lines (DL) at a display phase. The resistance and capacitance load of cabling in the active region of the touch panel is reduced, so that the working precision of the touch panel is improved.
