Abstract
An integral and internal matrix getter structure for capturing residual gas in a vacuum sealed container is disclosed. The vacuum sealed container may be a flat panel display having a small vacuum gap between two closely spaced panels. The getter structure may be provided on the inside of the walls of the display. In particular, the getter structure may be provided between phosphor groups and/or between field emitter groups on the display panels. The getter structure may be sealed to avoid exposure of the getter material until after a vacuum condition is reached within the display. Activation of the getter structure may be provided by selectively heating the getter structure with a laser or with resistive heating elements underlying the getter structure. Methods of making the getter structure are also disclosed.
