眼镜式3D显示设备综合性能测试方案的研究
Measurement and evaluation of comprehensive performance in 3D Display with glasses
摘要
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179%,垂直方向串扰呈振荡分布,时分式3D显示器的串扰最低,达037%[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697 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727%,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03%。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。
Abstract
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 programs 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 179% in the horizontal direction while it appears an oscillation distribution in the vertical direction. Besides, division type 3D display has a lowest crosstalk ratio with 037%. A luminance decline occurred in glasses 3D displays, especially for the division type 3D display: luminance remains only 697 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 727% in a standard of NTSC after a significant decrease. And the smallest color gamut existed in color type 3D display with 03%. These results can be used to improve the properties of glasses 3D displays.
