Crosstalk homogeneity measurement of different types of 3D displays
We measure the crosstalk of different 3D displays not only at one location but on the entire display surface. The measurements are made using high sensitivity video luminance-meter coupled to viewing angle instruments. An auto-stereoscopic 3D display is imaged for different lateral positions of the video luminance-meter located at the display working distance. Crosstalk homogeneity on the entire surface of the display is deduced. We show that the crosstalk is optimized on most of the surface of the display but local imperfections like scratches and marks increase drastically the crosstalk. For passive glass 3D displays, a vertical modulation of the polarization state of the light is generally observer that increases the crosstalk outside of the qualified binocular viewing space (QBVS). It is due to the alignment of the quarter wave film stripes with the pixel structure of the display. Using a video luminance-meter across one of the glass filters in the middle of the QBVS, we show that local defect can be detected on passive glass 3D TVs. They are due to a local misalignment of the quarter wave film stripes as observed using a Fourier optics instrument on the defect and outside the defect.
