Method of making a parallax barrier, parallax barrier and autostereoscopic display

摘要: A parallax barrier is made by developing a film exposed through mask having elongate opaque regions interleaved with transparent regions. The light source the while moved so as to vary exposure of each region for forming slit edges. Alternatively, or may be during exposure. It thus possible make soft edge barriers, example use in autostereoscopic 3D displays.
