<p>A display with at least two prism structure types. Type 1 includes prism 16A, color filter FY associated with one prism facet, and control members CC, CM, each biasable with respect to one of the prism's other two facets. Filter FY and members CC, CM have first, second and third spectral absorption characteristics. Type 2 includes prism 16B, color filter FB associated with one of that prism's facets and control member CK1 biasable with respect to one of that prism's other two facets. Filter FB and member CK1 have fourth and fifth absorption characteristics. For any selected set of proximate ones of each prism type, controlled movement of the members between selected combinations of positions causes the whole set to reflect light whose average spectral reflectance corresponds to one of three independent colors, none of which is obtainable by mixing any other two.</p> |
