LCD 屏蔽(EMI/ESD)


带有内置触摸功能的 LCD IPS 技术在高端智能手机显示屏中大行其道。Clevios® 屏蔽层帮助提升其制造工艺和光学特性。

虽然液晶显示器是一项成熟的技术,但仍在不断发展以提高其性能。

在现代显示器中采用 IPS 技术是一个重要的里程碑,它改善了色彩、对比度和视角。

溅射工艺的难点

然而,IPS LCD 技术容易产生静电和 ESD(静电放电),因此需要屏蔽层来保护显示屏。通常,在彩色滤光片玻璃上溅射一层薄薄的 ITO(铟锡氧化物)就足够了。然而,随着显示玻璃越来越薄、基板尺寸越来越大,ITO 溅射工艺的难度也越来越大。与溅射工艺相比,狭缝模头或喷涂等湿法涂覆技术具有更快的生产吞吐量、更少的停机时间以及更高的材料良率。

先进配方

贺利氏提供先进的导电聚合物配方——Clevios® F ELO,该配方专为显示玻璃上的光学级涂层进行了优化。该产品可通过经济高效的湿法涂布工艺涂覆在显示屏上,作为屏蔽层使用。其主要特点包括:优异的光学性能、可精确调节且均匀的片电阻,以及高硬度和高耐久性。

控制光反射

在光反射损耗方面,Clevios® 凭借其约 1.5 的较低折射率(与玻璃折射率高度匹配),明显优于 ITO。与 ITO 涂层相比,光反射可降低多达 50%。这有助于提高显示屏的对比度,例如在光反射问题突出的汽车内饰应用中。

在光反射损耗方面,Clevios™ 的折射率较低,约为 1.5,与玻璃相当,因此明显优于 ITO。与 ITO 涂层相比,光反射最多可减少 50%。这有助于提高显示屏的对比度,例如在光反射是一个难题的汽车内饰应用中。
