Abstract
By desorption processing of a flat panel display in a vacuum before hermetic sealing, it is possible to reduce operational outgassing. The first embodiment involves plasma scrubbing, the second embodiment involves electron irradiation pre-aging, and the third embodiment involves electron irradiation pre-aging of the faceplate in an evacuation process.
Claims5
A method for manufacturing a flat panel display comprising the steps of:
- providing a baseplate and a faceplate;
- desorption processing the faceplate in a vacuum;
- merging the baseplate and the faceplate while still in the vacuum after the step of desorption processing the faceplate;
- and
- sealing the vacuum between the baseplate and the faceplate;
- wherein the step of desorption processing includes a step of pre-aging the faceplate;
- wherein the step of pre-aging the faceplate is performed from 120 to 300 minutes;
- and
- wherein the step of desorption processing includes a step of pre-aging before merge of the baseplate and the faceplate.
