| Abstract (English): |
For miniaturization, thinner, high PPI(300+) and high aperture ratio of the high-generation line's TFT-LCD panel, improvement of Ass'y margin is the essential technology. Through array and CF key position/size matching optimization and discrete optimization, we try the non-linear offset of array TP, and optimize the process of cell glass turn over, sealant design and sealant coating, the Ass'y margin is improved from 7.5 μm to 5.5 μm of television, monitor, notebook and tablet PC. By solving touch Mura issue of monitor and pixel light leakage issue of tablet PC, the contribution to TFT-LCD panel aperture ratio also increases with the increasing of product PPI. For product with PPI 300+, the aperture ratio increase 14.8%. Effectively enhance the core competitiveness of small size and high PPI TFT-LCD product, the profitability and product mix of the high-generation line. In addition, the establishment of the analysis method, countermeasures review and standard process of the high-generation line's TFT-LCD panel Ass'y margin, the array TP non-linear offset and cell dummy sealant design guide of new TFT-LCD product are formed.

| Abstract (Chinese): |
:对盒精度提升是高世代TFTＧLCD面板生产线产品小型化、薄型化、高PPI(３００＋)与高开口率升级的必备核心技 术.通过阵列(Array)与彩膜(CF)关键位置/尺寸匹配性优化与离散性优化,首次尝试阵列关键位置精度(TP)非线性补 正功能,并钻研成盒(Cell)过程中基板翻转稳定化、封框胶设计与涂布工艺优化,实现电视机、显示器、笔记本、平板电脑 等产品对盒精度由７．５μm 降低至５．５μm;在解决显示器产品按压Mura与平板电脑产品像素漏光的同时,对产品开口 率的贡献也随着产品PPI的升高而增加,PPI３００＋产品的开口率余量提高１４．８％,有效提升了高世代TFTＧLCD面板生 产线小尺寸/高PPI产品核心竞争力、收益性和产品群组合.另外,本文建立高世代TFTＧLCD 面板生产线对盒精度分 析方法、对策检讨及改善的标准流程,形成新产品阵列TP非线性补正和对盒辅助封框胶的设计基准.
