Abstract
A display screen having phosphor regions maximizes light leaving the phosphor regions using a gaseous, liquid or solid matter that is disposed between the light-producing phosphor regions and a divider member configured to separate the light-producing phosphor regions. The gaseous, liquid or solid matter may be air, a polymer, a gel, or other material that optically separates and has an index of refraction substantially less than the indices of refraction of the divider member and the light-producing phosphor regions.
