A field emission flat panel display utilizes get- tering material to absorb gasses and maintain ade- quate display vacuum after seal. During the seal process the anode and cathode are held in parallel, separated from each other in a seal fixture. The frit frame lies on top of the cathode, and the getters are loaded into retaining tabs on the frit frame. The entire fixture is then loaded into a vacuum sealing oven where it is pumped down to meet the high vac- uum requirement, and is ramped up in temperature. Once the frit sealing temperature has been achieved, the fixture is forced together completing the seal process.
