Abstract (en)
[origin: CN101833184A] The invention provides an integrated structure of a capacitive touch pad and a liquid crystal display panel. In the integrated structure of the capacity-type touch pad and the liquid crystal display panel, a first touch inductive electrode layer is formed above an upper polaroid of the liquid crystal display panel, a second touch inductive electrode layer is formed below the upper polaroid of the liquid crystal display panel, and a touch object is respectively inducted with the first touch inductive electrode layer and the second touch inductive electrode layer to generate a corresponding capacitive coupling relation so as to achieve the touch effect.
