Abstract
The present invention is directed to color electroluminescent displays comprising a novel sub-pixel structure and method for making the same. The sub-pixel structure has an electroluminescent phosphor, which emits blue light, and a photoluminescent phosphor, which emits at least one other color as a result of absorption of the blue light. The invention is also directed to novel photoluminescent phosphor materials.

54. A photoluminescent phosphor material for emissive displays, said material comprising:
-
a pigment powder comprising a solid solution of organic photoluminescent molecules; and
a matrix material, wherein said pigment powder is dispersed in said matrix material, said matrix material being chemically and physically compatible with said pigment powder such that the photoluminescent efficiency of the organic photoluminescent molecules are substantially maintained. - View Dependent Claims (55, 56, 57, 58, 60, 61, 62, 63)
