共面电场切换液晶显示器面板技术发展回顾与展望 　　摘要：介绍IPS液晶显示技术的发展史、现况及对未来发展趋势的展望。在IPS技术克服了视角依存的显示基本需求特性，近来在动画质量与色彩再现稳定性方面亦大幅提升。现阶段开发重点则是着重于面板制造低成本、高生产良率和高对比特性，使其能与其它液晶电视技术匹敌。因此，我们成功开发了最具竞争力的新IPS模态，取名为AS-NOOC。与AS-IPS相比较，AS-NOOC具有省去一道Array基板侧的厚有机层制程的低制造成本优势，可大幅提高良率。并利用在彩色滤光片侧导入最佳化电极来同时优化面板亮、暗态的光学特性，有效提高对比度。 　　关键词：薄膜晶体管液晶显示器；共面开关；ＡＳ－ＮＯＯＣ 　　中图分类号：TN141.9 文献标识码：B 　　 　　Recent Progress and Future Possibility of 　　the IPS TFT-LCD Panel Technology 　　 　　Jiunn-Shyong Lin, Po-Sheng Shih, and Kei-Hsiung Yang 　　( Research Center, HannStar Display Corporation, Yang-Mei, Tao-Yuan, Taiwan,China) 　　 　　Abstract: The recent developments on the in-plane switching (IPS) TFT-LCD technology are reviewed in this paper. After IPS suppressing the viewing-angle dependency of essential display characteristics, recent efforts are focused on the improvements of motion-picture quality and color-reproduction stability. The most recent development has been to lower the panel-manufacture cost；higher process yield and higher contrast ratio, by which we will be able to compared with other LCD-TV technologies. Consequently, a novel low-cost and high contrast-ratio IPS LC mode, named Advanced Super Non-Organic Overcoat (AS-NOOC), has been successfully developed. Compared to the AS-IPS mode, the AS-NOOC mode has the advantages of simpler process for lower manufacture cost by the elimination of a lithographic process step to form thick organic overcoat on the array substrate, and consequently, resulting in a higher array yield. The higher contrast ratio comes from using narrow strips of black matrix serving as optimized electrodes on the color-filter substrate to optimize the optical properties in both the dark and bright states of the display. 　　Keywords: TFT-LCD；IPS；AS-NOOC 　　 　　1前言 　　 　　薄膜晶体管液晶显示器（TFT-LCD）产业在基础和应用方面急速扩展，成长速度超过了预期，随??电视平板化的趋势来临，液晶电视(LCD-TV) 无疑是液晶产业近年来最耀眼的今日之星。在全球每年约有1.7亿台电视机市场中，液晶电视将成为今后替代显像管电视(CRT-TV)的主要商品，可望继液晶监视器(LC monitor) 取代显像管监视器(CRT monitor) 后，再创显示器史上另一次“取代”的奇迹。然而，大尺寸液晶电视面板在开发技术上，需克服视角
