Abstract
The required luminance for information display is near 300cd/cm/sup 2/ for white. The amount of emitted light in phosphor screen depends upon the anode voltage and electron density from field emitter arrays. Field emission displays to date do not use the high accelerating voltage but a great number of cold electrons from field emitter arrays for required brightness. In these situations, coulombic loading on the phosphors should be minimized for a long lifetime. It was found that the introduction of a wide band-gap material to the oxide phosphors was effective for the prevention of accumulation of the electrons on the surface of phosphors.
