A touch panel includes: a glass cover plate including a display area and a non-display area located at an outer edge of the display area; and a touch sensing module laminated on the glass cover plate. The touch sensing module includes a first conductive layer and a second conductive layer. The first conductive layer includes a plurality of first conductive strips; the second conductive layer includes a plurality of second conductive strips. The touch sensing module includes a sensing area defined by edges of the first conductive layer and the second conductive layer. The sensing area includes a visual area and a non-visual area located at an outer edge of the visual area. A projection of the visual area on the glass cover plate coincides with the display area, a projection of the non-visual area on the glass cover plate falls within the non-display area.

The present invention discloses a double-layer touch screen, comprising: a transparent cover glass; a first transparent embossed adhesive layer; a first conductive layer embedded in the first transparent embossed adhesive layer and including a plurality of first conductive strips extending along a first direction, the first conductive strip is formed by intersection of conductive wires; a second transparent embossed adhesive layer; a second conductive layer embedded in the second transparent embossed adhesive layer and including a plurality of second conductive strips extending along a second direction, wherein the second conductive strip is formed by intersection of conductive wires; and a transmission reinforcement layer. The double-layer touch screen uses the first conductive layer and the second conductive layer to replace ITO layer used in conventional touch screen. This type of double-layer touch screen can ensure light transmittance and conductivity and reduce cost due to the cheaper material, without additional etching technique.
