Abstract:
A method for producing a field emission display (FED), comprising the steps of:providing electrodes of an anode structure on a first substrate; providing electrodes of a cathode structure on a second substrate; covering the electrodes of the anode structure with a luminescent material; placing the first substrate against the second substrate, with the electrodes of the anode structure facing the electrodes of the cathode structure; sealing a space between lateral edges of the first substrate and the second substrate in a gas-tight manner except for a gas inlet and a gas outlet connection; introducing a carrier gas between the cathode structure and the anode structure and flowing the carrier gas through the gas inlet and gas outlet connections; heating the electrodes of the cathode structure to a deposition temperature; depositing field emitters on the electrodes of the cathode structure at the deposition temperature from the carrier gas introduced between the cathode and the anode structure; and sealing the gas inlet and a gas outlet connections.
