Field emission displays (FEDs) having improved structure are provided. In one
implementation, a field emission display comprises a faceplate, a backplate, a
volume formed therebetween and maintained as a vacuum, a cathode and an anode.
A thickness of the faceplate and the backplate are sufficient to prevent deformation
of the faceplate and the backplate across their dimensions due to the vacuum such
that spacers are not needed to maintain a uniform separation between the anode
and the cathode. In an alternative implementation, the volume includes a first
portion between the cathode and the anode and a second portion between the cathode
and the backplate, the second portion continuous with the first portion. The second
portion provides an improved volume to surface area ratio, which improves vacuum
quality and which allows for improved gettering, which again allows for improved
vacuum quality and longer display lifetime.
