Abstract
A light transmission touch panel comprises a transparent substrate, a first transparent conductive layer, an insulation layer and a second transparent conductive layer, wherein the first transparent conductive layer, the insulation layer and the second transparent conductive layer are patterned and overlaid on a surface of the substrate. The first transparent conductive layer and the second transparent conductive layer are either on a surface or respectively on two opposite surfaces of the insulation layer. An electrical field having a component along the surface of the substrate occurs between two adjacent portions of the first transparent conductive layer and the second transparent conductive layer once they are electrically charged. When an article touches the touch panel, the intensity of the electrical lines is accordingly changed so that the touch panel can detect where the touch position is.
