Computation of the resultant chromaticity coordinates and luminance of combined and filtered sources in display design

Display designers are confronted by many possible emitters, filters and reflectors which can be used in order to produce a display to be viewed under varied or various illuminations. Often it is not possible to evaluate the perceptual performance associated with various combinations of these components until the whole configuration is assembled. A program is described which allows the resultant chromaticity coordinates of combined and filtered sources to be computed. The program allows the designer of complex display systems to make an evaluation of perceptual performance prior to construction. Examples are given which illustrate the use of the program.
