 背景技术
液晶显示器已经广泛用于人们生活中，例如手机、电脑、电视机等的显示屏幕。随着显示技术的发展以及人们对显示技术的进步要求，窄边框液晶显示器与全面屏液晶显示器已经应用在手机与笔记本等终端上。窄边框液晶显示器与全面屏液晶显示器通常会使用COF（Chip on Film，覆晶薄膜）结构，即显示芯片绑定于COF薄膜上，再通过COF薄膜绑定至阵列基板焊盘区。这样，具有COF结构的液晶显示器可以实现极窄的下边框。
目前，内嵌触控的液晶显示器在彩膜玻璃表面制作过程中需要使用高阻膜，这是由于高阻膜可以起到防静电的作用，具体地，通过银胶等导电物质将高阻膜连接至阵列基板，以避免静电现象。但是，如果所使用的银胶高度（即厚度）太大，会不利于下边框宽度减小，而使用的银胶高度太小，则会造成银胶与高阻膜接触不良。
因此，如何有地效解决实现窄边框面板且不影响其抗静电能力，是显示技术中的一项重要课题。
