Patent ID: 10566354

Abstract:
An array substrate used for a touch display screen is provided. The array substrate comprises a substrate; a polysilicon layer disposed on the substrate; a dielectric layer disposed on the polysilicon layer and the substrate; a touch line, a connecting line and data line arranged sequentially at intervals on the dielectric layer; a planarization layer covering the connecting line and data line; wherein a first through-hole and second through-hole arranged sequentially at intervals are formed on planarization layer, the touch line is facing and exposed from first through-hole; a portion of the connecting line is facing and exposed from second through-hole; a source and drain in contact with a portion of the surface of polysilicon layer are formed in dielectric layer arranged at intervals, the drain and source are respectively connected with the connecting line and data line, and the first through-hole is completely misplaced with the second through-hole.
