摘要
A pump is used to reduce the pressure in a field emission display package. The package is then filled with a gas or gas mixture, such as nitrogen and hydrogen. The package is then pumped again, to reduce the pressure in the package to the desired pressure and to obtain the desired partial pressure of the gas. Optionally, the process is then repeated, with a gas or gas mixture again inserted into the package and then the pressure reduced with a pump. After pumping, the package may be heated to cause outgassing and to activate a getter. The pumping is performed with a mechanical pump, an ion pump, or a combination of the two types of pumps.
