Means Preventing Forgery and Falsification Using Light Polarizing Layer and Piezochromic Fluorescence Layer |
| abstract |
The present invention is a substrate; a design print layer located on the upper side of the substrate and printed with a specific shape; a cholesteric liquid crystal display layer positioned on the design print layer and printed with a hidden shape; and an autochromic fluorescent layer positioned on the cholesteric liquid crystal display layer. In the case of checking whether forgery or not by illuminating the smart phone screen light on the forgery prevention means of the present invention or applying pressure to the forgery prevention means, the forgery is very difficult, easy to manufacture, and inexpensive. It provides the advantage of being able to detect forgery even without a forgery checking device. |
