摘要

众多广视角技术中，高级超维场转换技术（Advanced Super Dimension Switch，ADS）具有高分辨率、高透过率、低功耗、宽视角、高开口率、低色差、无挤压水波纹（Push Mura）等优点。与垂直取向（Vertical Aligned，VA）模式相比，ADS模式存在对比度（Contrast Ratio，CR）偏低的问题。本文主要从设计及材料两个方面对ADS显示模式超高清（Ultra High Definition，UHD）产品对比度提升进行研究。与传统的产品相比较，在设计方面采用了高透像素设计，在提升L255亮度的同时，保证L0亮度不变；同时开发了一种低散射液晶，降低L0亮度，明显改善对比度。将高透像素设计搭载55UHD和49UHD ADS产品进行了实验验证，将低散射液晶搭载49UHD ADS产品进行了实验验证。结果表明，采用高透像素设计的面板与传统设计面板相比，对比度提升约8.3%；采用高对比度液晶的面板的与传统设计面板相比，对比度约提升22%。二者共同作用，UHD产品对比度提升约30%。

Abstract

Advanced super dimension switch(ADS) technology have many advantages

such as high resolution

high transmittance

low power consumption

wide view angle

high aperture ratio

low color shift

no push Mura

etc.

Compared to VA(Vertical Aligned) mode

low contrast ratio is the disadvantage of the ADS mode. New pixel design

new LC(Liquid Crystal) for CR(Contrast Ratio) improve ment

is proposed in this paper. By using high transmittance pixel design

L255 luminance is improved and L0 has no change

the CR is improved by 8.3%(Test on 55UHD

49UHD Product). By developing low scattering LC

L0 luminance is decreased and L255 has no change

the CR is improved by 22%(Test on 49UHD Product). CR is totally improved by 30%.
