Abstract:
1. A packaging method of an electron emission device, comprising: providing an electron emission device comprising a first substrate and a second substrate, wherein the first substrate has a cathode thereon, the second substrate has an anode thereon, and a phosphor layer is disposed on the cathode or anode; forming a sealant between the first substrate and the second substrate, wherein the sealant has an opening; disposing a tube at the opening of the sealant; connecting the tube with a pipe, wherein the pipe connects to a gas-exhausting apparatus and a gas-filling apparatus; heating the electron emission device and exhausting the gas in the electron emission device by using the gas-exhausting apparatus; turning off the gas-exhausting apparatus and turning on the gas-filling apparatus so as to fill a gas into the electron emission device; and blowing the tube so as to seal the opening of the sealant.
