ABSTRACT:
A FED is provided comprising: an emitter located on a cathode; a pixel located on an anode positioned to receive electrons from the emitter; and a getter located on the anode. According to another aspect of the invention, a method of making an FED is provided comprising: depositing getter material over a tip on a cathode; assembling the cathode with an anode, wherein the getter is between the tip and the anode; and activating the getter, whereby the activation causes the getter to be deposited on the anode.
