摘要

由于市场以及客户对液晶显示的广视角需求越来越多，1996年出现了FFS（Fringe Field Switch）技术，其相对于IPS（In-Plane Switching）技术，液晶模组的分辨率具有一定的提高。京东方通过对FFS技术在材料、设计以及工艺上的改善，形成了更为先进的ADS（Advanced Super Dimension Switch）技术，ADS液晶模组具有广视角、高亮度以及高开口率等优点。尽管ADS液晶模组具有很多优势，但同时该模组具有较强的敏感性，在ADS模组受到外力的挤压作用时，容易产生漏光现象（也可称为应力Mura现象），影响客户端的视觉效果。本文研究了承载液晶面板的泡棉对液晶模组漏光的影响，高压缩比（75%）高厚度（0.4~0.6 mm）泡棉相对于常规泡棉，受到同样的作用力压缩量更大（同时进行了理论计算和实际测量），该泡棉对模组漏光现象改善明显，不仅提高了模组的良率，也可以改善客户端对产品的视觉效果。

Abstract

The market and customers demand more and more LCD displays with wide range. FFS (Fringe Field Switch) technology appeared in 1996

with higher resolution than IPS(In-Plane Switching)technology. Through improving FFS technology in materials

designs and processes

BOE has formed ADS (Advanced Super Dimension Switch) technology

which has wide angle of views

high brightness and high aperture rate and so on. Although the ADS LCD module has many advantages

the module has a strong sensitivity at the same time. By the external force

it can produce light leakage phenomenon (also known as Mura phenomenon) easily

which may affect the client visual. In this paper

the effect of foam on the light leakage is studied. The deformation with high compression ratio and the high-thickness foam is larger than that of the conventional foam with same force (the theoretical calculation and the actual measurement are carried out at the same time). Light leakage will be reduced significantly with the foam mentioned above

which can not only improves the yield

but also improve the client's visual.
