为了更系统、科学地评价眼镜式立体设备的显示质量,本文对目前主流的眼镜式3D 显示器进行串扰率、亮度、对比度、色温、色域的测量.首先,根据眼镜式立体设备的成像原理设计相关的测试方案.测试结果表明,色分式3D 显示器左眼串扰为3％,右眼为9％,偏振式3D 显示器水平方向串扰最低为1.79％,垂直方向串扰呈振荡分布,时分式3D 显示器的串扰最低,达0.37％；眼镜式3D 显示器的亮度在3D 模式下均发生较大程度的下降,其中时分式3D 显示器在3D模式下亮度仅为6.97 cd/m2,其对比度也随之发生大幅下降；色域方面,时分式显示器在3D 模式下色域覆盖率为72.7％,相比2D 模式存在明显下降,而色分式3D 显示器在3D 模式下的色域覆盖率最小,仅为0.3％.上述数据可为设备的选择和产品性能的优化提供有益参考作用.
Five key indicators,including crosstalk ratio,luminance,contrast,color temperature,color gamut,were measured in the three mainstream glasses 3D displays.First,a series of measuring pro-grams were designed according to imaging principle of glasses 3D displays.Measurement results show that the crosstalk ratio of color type 3D display is highest which the left eye is 9% while the other one is 3%.On the other hand,the crosstalk ratio of polarization type 3D display is 1.79% in the horizon-tal direction while it appears an oscillation distribution in the vertical direction.Besides,division type 3D display has a lowest crosstalk ratio with 0.37%.A luminance decline occurred in glasses 3D dis-plays,especially for the division type 3D display:luminance remains only 6.97 cd/m2 in 3D play mode with a substantial decline in contrast.In color gamut area,compared with 2D play mode,division type 3D display still has a color gamut of 72.7% in a standard of NTSC after a significant decrease.And the smallest color gamut existed in color type 3D display with 0.3%.These results can be used to improve the properties of glasses 3D displays.
