Liquid crystal flexible display film suitable for anti-counterfeiting trademarks
This article designs a liquid crystal flexible display film with excellent mechanical properties and unique anti-counterfeiting functions.Firstly,a liquid crystal display device with dual channel display function is designed based on optical orientation technology,which achieves independent display of two channels through light field control.Secondly,using the thickness of the LCD box as the control group,the optimal thickness is determined to enable two independent patterns to form the main and auxiliary display effects,thereby hiding anti-counterfeiting information.Finally,the mechanical tensile properties of liquid crystal display films are improved by doping silver nanowires(AgNWs)into liquid crystal polymer composites.The experimental results show that when the thickness of the liquid crystal flexible display film is 60 μm,the liquid crystal film presents a satisfactory pattern display effect.Meanwhile,compared with the liquid crystal display film without AgNWs doping,the modulus parameter of the liquid crystal flexible film doped with AgNWs is increased by more than 30%,and it has a larger stress-bearing capacity and strain range.This study has positive significance for achieving a liquid crystal anti-counterfeiting trademark with rich information and strong stability.
