Abstract:
1. A method of making a flat panel field emission display comprising the steps of: providing a phosphor coating on a display screen; arranging an emission source opposite said display screen for selectively exciting portions of said phosphor coating to generate visible light during subsequent operation; and providing a black matrix on said screen, said black matrix being formed from praseodymium-manganese oxide; wherein said black matrix forming step includes patterning a photoresist material on said screen to expose only those areas of the screen on which the black matrix is to be deposited; depositing said praseodymium-manganese oxide; and removing said photoresist material; and said step of providing a phosphor coating is performed subsequent to said black matrix forming step and includes patterning a second photoresist material to expose only those areas of the screen on which said phosphor coating is to be provided; depositing said phosphor coating; and removing said second photoresist material.
