Abstract
A new method for forming an anode plate for a color flat panel Field Emission Displays (FEDs) having improved gettering, was accomplished. The method involves forming on a transparent insulating plate (glass) an array of pixels of three phosphors comprising the primary colors and having in or/and around the array of pixels gettering material to provide more efficient gettering of volatile material from the FED cavity. The electrons are injected into the pixels when the electron field emitters are electrically accessed via the address and image forming circuits. The injected electrons heat and activate the gettering material in and around the pixels and provide very effective gettering in the FED cavity.
