Description

获取液晶显示面板缺陷位置的方法及液晶显示面板缺陷定位装置 技术领域
本发明涉及显示技术领域，尤其涉及一种获取液晶显示面板缺陷位置的方法及液晶显示面板缺陷定位装置。
背景技术
随着显示技术的发展，液晶显示器(Liquid Crystal Display，LCD)等平面显示装置因具有高画质、省电、机身薄及应用范围广等优点，而被广泛的应用于手机、电视、个人数字助理、数字相机、笔记本电脑、台式计算机等各种消费性电子产品，成为显示装置中的主流。
通常液晶显示装置包括壳体、设于壳体内的液晶显示面板及设于壳体内的背光模组(Backlight module)。其中，液晶显示面板的结构主要是由一阵列基板(Thin Film Transistor Array Substrate，TFT Array Substrate)、一彩膜基板(Color Filter Substrate，CF Substrate)、以及配置于两基板间的液晶层(Liquid Crystal Layer)所构成，其工作原理是通过向TFT基板的像素电极和CF基板的公共电极上施加驱动电压来控制液晶层的液晶分子的旋转，将背光模组的光线折射出来产生画面。
由于液晶显示面板成像必须依靠偏振光，因此在阵列基板与彩膜基板两侧均贴附有偏光片，当偏光片贴附不良时需要重工，即撕除偏光片后再重新贴附偏光片，但现有技术中撕除偏光片后，作业人员只是大而广泛的检查整个液晶显示面板表面是否有异物残留并擦拭，或者对液晶显示面板整面直接擦拭，这样的作业方式使作业人员作业效率较低，没有针对性，如果液晶显示面板上的残留异物没有被擦拭干净，重新贴附偏光片后将再次被返工。
发明内容
本发明的目的在于提供一种获取液晶显示面板缺陷位置的方法，能够在定位平台上精确定位液晶显示面板的缺陷，提高作业效率，防止液晶显示面板多次重工，从而减少偏光片的损失。
