A model of the fast-switching polymer-stabilized in-plane-switching configuration

Abstract— A significant improvement in the dynamic response times of IPS-mode LCDs is achieved through polymer stabilization. The improvement is a result of the introduction of a low-density stabilizing polymer network that causes the LC director to favor the zero-field orientation. We report on the effect of the polymer concentration and network orientation on the electro-optic performance of our novel polymer-stabilized IPS-mode cells. Furthermore, we present a detailed model derived using elastic continuum theory to explain our observations.

论IPS是否可以彻底取代IDS

IPS(入侵防护系统)一经问世就立刻成为网络安全领域的宠儿,其原因在于IPS提出主动对主机和网络运行情况进行实时监控,具备自动阻截和在线运行的功能。如果单从理论和技术的角度来说,比起只能被动监视的IDS(入侵检测系统)而言,IPS确有许多优势,但IPS果真如理论中那么完美吗?在实际应用中,IPS仍存在性能瓶颈、误报率高、单点故障、自主安全等方面的缺憾。因此IPS全面取代IDS的时代尚未到来。     

共面电场切换液晶显示器面板技术发展的回顾与展望

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。     

LCDs for TV applications

Abstract— Super IPS (S‐IPS) technology has intrinsic advantages in several aspects required for TV applications. Particularly, the wide‐viewing‐angle property and fast gray‐to‐gray response time of S‐IPS LCDs are both necessary requirements for family and individual use for LCD TVs. Given these benefits and other advantages S‐IPS provides, LG.Philips LCD has developed high‐performance S‐IPS LCDs for TV, which have now become competitive with plasma‐display panels (PDPs), in addition to other modes of LCD TVs as well as CRTs. This article will discuss why S‐IPS technology is the leading choice for LCD‐TV applications.     

A high‐aperture‐ratio and low‐crosstalk pixel structure design for in‐plane‐switching‐mode TFT‐LCDs

Abstract— The TFT‐LCD market is growing rapidly, and the replacement of CRT TV by LCD TV requires the implementation of LC modes with wide viewing angles and high brightness. The IPS mode is an excellent technology to realize wide viewing angles, but it has a low aperture ratio that has now been improved by Advanced Super‐IPS (AS‐IPS). In this paper, we propose a novel pixel structure design that not only increases the aperture ratio but also reduces the crosstalk. We have improved the current AS‐IPS aperture ratio by 1.25 times and effectively reduced the capacitive coupling ratio from 1.2% to 0.05%.

Advanced IPS technology for mobile applications

Abstract— In‐plane‐switching LCD (IPS‐LCD) technologies originally developed for LCD monitors and TV applications are applied to mobile applications. Advantages of the IPS mode over other optical modes for mobile applications are quantitatively clarified. The panel achieves stable color reproduction and chromaticity in the viewing‐angle range for mobile displays. Superiority of the IPS mode over other optical modes is discussed also from the viewpoints of stability in chromaticity during the brightness change and the driving power consumption. A transflective IPS mode with good performance is accomplished by the use of a proper optical design. A new structure, IPS‐Pro, which enables sunlight readability by increasing the transmittance, i.e., the brightness of the panel, without additional cost and power consumption in contrast to additional fabrication processes required to fabricate the transflective mode is realized. Furthermore, to improve the users' convenience, an automatic luminance control system and a controllable viewing‐angle device are developed. The panels developed fulfill the market requirements of increasing the function and performance variations and will be the most appropriate ones to be applied to mobile appliances, such as cellular phones, digital still cameras, music players, GPS, mobile TV sets, etc.
