[0005] Furthermore, the top cover plate and the bottom panel are selected from any one of glass, microcrystalline glass, acrylic, silk-screened PET and non-silk-screened PET.

[0006] Furthermore, the first adhesive layer and the second adhesive layer are made of any one of double-sided adhesive, OCA adhesive, water-based adhesive or SCA adhesive.

[0007] Furthermore, the thickness of the first adhesive layer and the second adhesive layer is 50-200 μm.

[0008] Furthermore, the light transmittance of the first adhesive layer and the second adhesive layer is ≥90%.

[0009] Furthermore, the sensing layer is an ITO sensor.

[0010] Furthermore, electrode leads are printed on the edges of the sensing layer.

[0011] Furthermore, an explosion-proof film is attached to the top cover plate and / or the bottom panel.

[0012] The beneficial effect of the utility model is that the top cover plate is bonded to the sensing layer through the first adhesive layer, and then the second adhesive layer is covered on one side of the top cover plate on the back of the sensing layer and bonded to the bottom panel, and the touch function can be realized by touching the top cover plate or the bottom panel, thus realizing double-sided touch.
