LOCA液态光学胶-触摸屏接着应用材料
AT-5352-2液态光学胶可接着於玻璃舆ITO玻璃接着應用,以提高顯示器對比。舆傳统採用空氣间隙的方法相较,LOCA液态光学胶可抑制外部光照舆背光等遵致的光散射情况。
迅速反应成型的LOCA液态光学胶具有舆玻璃相近的折射率及穿透率、耐黄化、且具有良好的可撓性,能够接合热膨胀系数差異很大的两种材料,可抵挡贴合時高低温变化产生的问题。
LOCA液态光学胶优点Advantage
因消除空气间隙使得模组空间更薄Thinner sizing by eliminating air gap
面板承受力度增加lncrease the panel strength
因可控制折射率,使得書面亮度興对比度增加lincrease brightness﹠Contrast by refractive index control
面板可视角度增加lncrease the viewing angle
更可减少成本支出Reduce costs
产品特色:Feature
(1)UV固化后具有高透光性、高折射率、低收缩等特点The cured adhesive exhits high transparency,high refractive indexand low volme shrinkage
(2)本产品有很好的柔软延展性,适合不同膨胀系数材质接着When cured,the flexibility of LOCA makes it ideal for applications involving dissimilar surferces where thermal coefficient of expansionmay be a problem
(3)通过信赖性测试,温低温循环,高低温冲击,高温高湿 ,高温烹煮Pass environmental test experiments,such asch as thermal cycle,thermal shock,high temp.+high humidity,pressure cook.
