  • Method for sealing and fabricating cap for field emission display
    Patent number: 6881116
    Abstract: A method for sealing and fabricating a cap in an FED is provided which is able to seal a cap in a vacuum space. The method includes fabricating a cap on which sealant is applied, locating the cap with the sealant on a substrate of a panel on which a hole is formed in a vacuum chamber, and hardening the sealant by irradiating laser onto the sealant, in order to prevent oxygen from inducing into the panel, and to prevent electrodes formed on the panel from being contaminated.
