Inorganic electroluminescent displays: the impact of new materials

An overview of inorganic EL (iEL) flat panel displays (FPD) is presented. This includes a summary of the key points of iEL device operation and on overview of the impact of new phosphors and dielectric materials critical in EL device operation. This is followed by in-depth review of iEL devices and displays utilizing rare-earth-doped GaN and transition-metal-doped ZnS, in conjunction with high dielectric constant insulating layers. Next, a brief status of companies in the iEL field is given. Finally, speculative concepts on combining inorganic and organic light emitting materials are discussed.
