摘要

对盒精度提升是高世代TFT-LCD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7.5

m降低至5.5

m；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，PPI 300+产品的开口率余量提高14.8%，有效提升了高世代TFT-LCD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TFT-LCD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。

Abstract

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

m to 5.5

m 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.
