Patent ID: 8203785

Claim:
A display screen, comprising: a plurality of screen layers forming a planar stack, the screen layers including: a fluorescent layer comprising a plurality of parallel fluorescent stripes, wherein the plurality of parallel fluorescent stripes each absorbs excitation light and emits visible light of a respective color, and wherein adjacent fluorescent stripes emit visible light of different respective colors; an entrance layer on a first side of the fluorescent layer to receive the excitation light and to direct the excitation light to the fluorescent layer; and a first filter layer on a second side of the fluorescent layer opposite to the first side wherein the first filter layer comprises a plurality of parallel, first filter stripes, each first filter stripe is aligned with a corresponding fluorescent stripe along a direction perpendicular to the screen layers, the first filter stripe transmits visible light of the respective color emitted by the corresponding fluorescent stripe and absorbs visible light of the respective colors emitted by other fluorescent stripes adjacent to the corresponding fluorescent stripe, wherein the fluorescent layer further includes a plurality of first stripe dividers, each first stripe divider being located between a pair of adjacent fluorescent stripes in the florescent layer and has side walls that are reflective and opaque, and wherein the first filter layer further includes a plurality of second stripe dividers, each second stripe divider being located between a pair of adjacent filter stripes in the filter layer and has side walls that are reflective and opaque.
