ABSTRACT:
A thin film phosphor screen structure includes a light-transmitting substrate layer, a phosphor layer on the substrate layer formed with a plurality of parabolic-shaped cells containing phosphor material, and a reflective layer coated over the parabolic phosphor cells for reflecting light generated in the cells for transmission externally through the substrate layer. The parabolic cells are configured corresponding to the desired resolution of the display and to critical angle of diffraction for the phosphor/substrate interface. An anti-reflection coating may be applied at the phosphor/substrate interface. The phosphor layer may have a graded dopant structure or an impressed electric field for causing generated electrons to migrate toward the focal plane of the parabolic phosphor cells.
