A multi-region light scattering element with the optical characteristics
of low speckle, high resolution high contrast, and high gain when used as
an imaging element without any resulting loss of transmission or
brightness with viewing angle. The multi-region light scattering element
contains at least one region asymmetrically shaped light scattering
features that are separated from a second light scattering region by a
non-scattering region. In one embodiment, one or more of the regions
contains particles that are asymmetrically shaped that improve the
optical performance. In one embodiment, asymmetric particles are located
in two regions separated by a non-scattering region with the particles
within each region substantially aligned along an axis and the two axes
are substantially perpendicular to each other. Methods for production of
the screen element are also described.
