Abstract
A getter assembly for use in a vacuum display panel is described. The novel getter assembly can be provided including both a non-evaporative getter and an evaporative getter which are uniquely positioned juxtaposed to each other such that ions emitted by the evaporative getter upon activation substantially shield the non-evaporative getter so that gases emitted by the non-evaporative getter when activated does not affect the state of vacuum in the vacuum display panel. A preferred embodiment of the present invention novel getter assembly is shown for vacuum display panels that have sufficient thickness in the cavity so that the getter assembly can be installed inside the cavity. An alternate embodiment of the present invention illustrates that when the cavity in the vacuum display panel is too small to accommodate the mounting of the getter assembly, an exterior mounting of the assembly is possible wherein one of the getters may be activated by a radio frequency induced current, instead of by feedthrough electrodes. By utilizing the present invention novel getter assembly which is uniquely positioned to compliment each other's functions, a high and stable vacuum state in a vacuum display panel device can be achieved and maintained, for instance, at between 10 and 10 Torr.
