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