Description                           

Longhua BLC-11x product line is specifically designed  light-guided substrate film for various  slim display applications. The roll to rolll fabrication process replicates microstructure offering similar optical performance as that of typical PMMA LGP within a 20"-range screen. Combined with advantages of PC, such as great heat-resist, high impact-resist, foldability & flexibility, excellent dimension stability and minimized color differentiation, it provides effective solution for thickness limitation of typical PMMA LGP on thin display , and for shrinkage distortion under  humidity test (60/RH 90%). Further, it eliminates extreme limits on PC LGP inject-molding thickness and dimension ratio. All makes itself best choice for back LGP of a variety of slim display monitors, tablets, mobilephones etc., as well as front LGP for E-books.
