    摘要： Projection screen assemblies include one or more birefringent retarding layers and one or more polarizing layers. The retarding and polarizing layers reduce the unwanted reflection of ambient and image light. One embodiment of a screen assembly includes a dispersing layer having an input side to receive light from a light source and a first retarding layer disposed to alter the polarization of the light transmitted by the dispersing film. A first polarizer substantially transmits light received from the first retarding layer in a first polarization state and absorbs light received from the first retarding layer in a second polarization state orthogonal to the first polarization state.

    摘要： In an acrylonitrile based retarder, relatively uniform performance is obtained as the angle of incidence varies over a wide range. A toughening material may be blended with an acrylonitrile based polymer to facilitate processing of a retarder and improve mechanical properties of the retarder without compromising the optical performance. A rubber-modified acrylonitrile based retarder which provides relatively uniform wide angle can be fabricated using conventional processing techniques. Such retarders are particularly suited for a number of specific applications which use relatively wide ranges of incidence angles.

    摘要： A composition which includes the following compounds: ##STR1## wherein R.sup.1, which may be the same or different, is a hydrophilic group;R.sup.2, which may the same or different, is selected from the group consisting of electron donating groups, electron withdrawing groups, and electron neutral groups;R.sup.3 is a substituted or unsubstituted, positively charged heteroaromatic ring linked to the triazine backbone through a nitrogen atom in the R.sup.3 ring; andX.sup.- is a counterion.If R.sup.3 is an unsubstituted pyridine, the counterion X.sup.- may be selected from any counterion other than Cl.sup.- and OH.sup.-. Otherwise, the counterion X.sup.- may be selected from any counterion.The compound may be applied to a substrate to form a birefingent optical retardationdevice. The retardationdevice may be used in display devices such as computers and the like to correct the phase and polarization states of the display's emitted light and improve image quality at viewing angles away from the normal.
