New approach on calculating multi-view 3D crosstalk for auto-stereoscopic displays

In this study, we suggest a new concept of 3D crosstalk for auto-stereoscopic displays and obtain 3D crosstalk values of several multi-view systems based on the suggested definition. First, we measure the angular dependencies of the luminance for auto-stereoscopic displays under various test patterns corresponding to each view of a multi-view system and then calculate the 3D crosstalk based on our new definition with respect to the measured luminance profiles. Our new approach gives just a single 3D crosstalk value for single device without any ambiguity and shows similar order of values to the conventional stereoscopic displays. These results are compared with the conventional 3D crosstalk values of selected auto-stereoscopic displays such as 4-view and 9-view systems. From the result, we believe that this new approach is very useful for controlling 3D crosstalk values of the 3D displays manufacturing and benchmarking of the 3D performances among the various auto-stereoscopic displays.
