【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6.97cd/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。
[Abstract]:In order to more systematically and scientifically evaluate the display quality of the glasses type three-dimensional device, the crosstalk rate, the brightness, the contrast, the color temperature and the color gamut of the current glasses type 3D display are measured. First, the related test scheme is designed according to the imaging principle of the glasses type stereoscopic device. The results of the test show that the left-eye crosstalk of the color-fraction 3D display is 3%, the right eye is 9%, the crosstalk of the polarization type 3D display is the lowest of 1.79%, the cross-talk in the vertical direction is in an oscillating distribution, and the crosstalk of the time-division type 3D display is the lowest, and the cross-talk is up to 0.37%; The brightness of the glasses type 3D display is greatly reduced in the 3D mode, wherein the brightness of the time-division type 3D display is only 6.97cd/ m2 in the 3D mode, and the contrast of the time-division type 3D display is reduced greatly; and in terms of the color gamut, the color gamut coverage rate of the time-division type display in the 3D mode is 72.7%, The color gamut coverage of the color fraction 3D display in the 3D mode is only 0.3%, as compared to the 2D mode. The above data can provide a useful reference for the selection of the device and the optimization of the product performance.
