ABSTRACT To reduce the operating voltage and gamma shift of the nematic liquid crystal display (LCD), a single-domain-protruded fringe-field switching (PFFS) electrode structure is designed. In this work, a kind of nematic liquid crystal (NLC) is introduced firstly. Then, the operating voltage and gamma shift of the proposed PFFS LCD are investigated under various electrodes’ parameters. Besides, its light leakage and contrast ratio are also discussed. The results show that the operating voltage of the PFFS LCD is only 1.40 V, here the electrodes’ width is 2 μm and electrodes’ gap is 4 μm. The gamma shift of the PFFS LCD can be reduced to the indistinguishable level under various electrodes’ sizes, if the height of the insulation layer is proper. For contrast ratio, it is larger than 200:1 at full viewing-angle, and the zone of 500:1 covers 60° polar angle. Graphical abstract

用于降低边缘场切换 LCD 的工作电压和伽马偏移的多层突出电极

摘要 为了降低向列液晶显示器 (LCD) 的工作电压和伽马偏移，设计了一种单畴突出边缘场开关 (PFFS) 电极结构。在这项工作中，首先介绍了一种向列液晶（NLC）。然后，在各种电极参数下研究了所提出的 PFFS LCD 的工作电压和伽马偏移。此外，还讨论了它的漏光和对比度。结果表明，PFFS LCD的工作电压仅为1.40 V，电极宽度为2 μm，电极间隙为4 μm。如果绝缘层的高度合适，PFFS LCD的伽马偏移可以降低到各种电极尺寸下无法区分的水平。对比度方面，全视角大于200:1，500区域：1 涵盖 60° 极角。图形概要
