【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]:In 1996, FFS(Fringe Field switch technology was introduced because of the increasing demand for wide view of LCD. Compared with the IPS(In-Plane switching technology, the resolution of the LCD module is improved to a certain extent. Beijing and Eastern through the FFS technology in the material. With the improvement of design and technology, more advanced ADS(Advanced Super Dimension switch technology has been formed. The ADS liquid crystal module has the advantages of wide viewing angle, high brightness and high opening rate. Although the ADS liquid crystal module has many advantages, it is also highly sensitive. When the ADS module is extruded by external force, it is easy to produce light leakage (also called stress Mura phenomenon). In this paper, the effect of foam on the light leakage of liquid crystal module is studied. The high compression ratio (75) and high thickness (0.40 mm) foam cotton are compared with conventional foam cotton. Under the same force, the compression is much larger (at the same time, the theoretical calculation and practical measurement are carried out, the light leakage of the module is improved obviously by the foam cotton, and the yield of the module is not only improved. It can also improve the visual effect of the client to the product.
