ABSTRACT:
A plasma display comprises a face plate; at least one energy source; a first layer comprising pigmented phosphors; and a second layer comprising non-pigmented phosphors. The at least one energy source emits energy that is capable of exciting the non-pigmented phosphors of the second layer. Thus, the non-pigmented phosphors of the second layer emit energy comprising visible light. The first layer comprising the pigmented phosphors acts as a filter to filter the emissions from the non-pigmented phosphors of the first layer. Therefore, the plasma display has at least an increase in contrast of the energy emitted therefrom.
