摘要

为满足液晶面板尤其是大尺寸产品对高透过率不断提升的需求，进行负型液晶在ADS广视角技术中的研究。首先，介绍ADS技术的发展进程及主要特点，然后模拟分析负型液晶参数变化对ADS显示特性的影响，最后，利用mini cell对负型液晶和PI材料的进行实验室评价。液晶参数中：Δ

影响透过率，|Δ

|和

值影响响应时间和工作电压，

影响响应时间。负型液晶透过率比正型液晶提升约8%，但响应时间增加约50%，负型液晶与PI的匹配性及残像差于正型液晶，与PI材料的搭配对残像有显著影响。调整负型液晶参数可优化产品性能。负型液晶可大幅提高产品的透过率，但需要加快响应时间和提升残像水平。响应速度的提高除了需要降低液晶的黏度，还需在电极结构优化方面做更多努力，而残像水平的提升，除提高负型液晶材料本身的稳定性外，与其搭配的取向材料的研发也十分重要。

Abstract

In order to meet the demand of high transmittance for large size products

we research the application of negative LC in ADS technology. First

we introduce the development progress and main features of ADS technology. And then

we analyze the relationship between negative LC parameters and ADS display characteristics. Finally

we evaluate the features of different negative LC matching with different PI materials. Among the parameters of negative LC

greatly affects on transmittance

|Δ

| and

mainly impact on response time and operation voltage

has great influence on RT. The transmittance of negative LC is about 8% higher than that of positive LC

but the RT is increased by~50%. The matching of negative LC and PI materials is worse than positive LC

and it has significant impact on imaging sticking. The product performance can be optimized by adjusting the negative liquid crystal parameters. The transmittance can be greatly improved by using of negative LC

but the response time and image sticking should be greatly improved for large size display. Response time can be fasted by lower

of LC

but it may be not enough

further optimizing the pixel structure is also necessary. Image sticking can be improved by enhancing the stabilized of LC

while the development of PI material for negative LC is also very important.
