Abstract
A ultra-high vacuum field emission display (100, 200) is disclosed including an anode (102, 202), a cathode (106, 206), side members (112, 212), a first non-evaporable getter material (120, 220) which is activated during the sealing and evacuation of the package, and a second getter material (122, 222) which is activated during the normal operation of the ultra-high vacuum field emission display (100, 200). The second getter material (122, 222) is activated by subsequent heating provided by radio-frequency radiation, resistive heating, or a laser.
