Abstract
Dual modulator displays are disclosed incorporating a phosphorescent plate interposed in the optical path between a light source modulation layer and a display modulation layer. Spatially modulated light output from the light source modulation layer impinges on the phosphorescent plate and excites corresponding regions of the phosphorescent plate which in turn emit light having different spectral characteristics than the light output from the light source modulation layer. Light emitted from the phosphorescent plate is received and further modulated by the display modulation layer to provide the ultimate display output.
