摘要

依据曲面显示测试标准IEC TS 62715-5-2~([1]),对曲面液晶显示器各显示区域白场亮度、对比度、色度(红、绿、蓝、白场)值进行测量,研究视角对曲面液晶显示器各显示区域白场亮度、对比度、色度(红、绿、蓝、白场)值的影响。研究表明商用曲面液晶显示器白场亮度、对比度随视角变化差异明显,暂时无法满足军用使用要求;白、红、绿、蓝场色度随视角变化不大,满足军用使用要求;商用曲面液晶显示器需要大幅度降低亮度、对比度随视角变化量才能应用于军用领域。
        The white brightness, contrast ratio, and chromaticity(red, green, blue, white) in each display area were measured according to the surface testing standards of IEC TS 62715-5-2. The characteristics of the white brightness, contrast ratio, chromaticity(red, green, blue, white) in each display area at different viewing angle were studied. We found that the white brightness, contrast ratio changed obviously when viewing angle changed which cannot be used in military special display for the time being. But the chromaticity(red, green, blue, white) almost unchanged which can be used in military special display.If the reinforced curved display devices want to be applied in military field, the change of white brightness and contrast ratio should be drastically reduced with viewing angles.
