[0039] Example 1
[0040] The easy-to-erasable liquid crystal film writing board includes a PET (polyethylene terephthalate) transparent film plated with ITO (smoky tin oxide conductive layer), a liquid crystal thin layer, PET non-transparent black film coated with ITO on one side; the conductive layer of the transparent PET film coated with ITO on one side and the non-transparent black PET film coated with ITO on one side are coated with an insulating layer.
[0041] The thickness of the PET transparent film coated with ITO on one side and the non-transparent black film of PET coated with ITO on one side are both 188 microns; the thickness of the insulating layer is both 2 microns; the thickness of the thin liquid crystal layer is 5 Micrometers.
[0042] The insulating layer on the conductive layer side of the PET transparent film plated with ITO on one side is polyvinyl alcohol acrylate tri-proof paint.
[0043] The insulating layer on the conductive layer side of the non-transpare...
