<p>An electron emitting structure, for example, for use as a cathode plate of a field emission display (FED). The structure comprise substrate (602), base electrodes (604a, 604b) formed on the substrate and gate electrodes (608a,..., 6QSf) crossing over the base electrodes. An insulating material (606) is formed on the substrate (602) and the base electrodes that separates the gate electrodes from the base electrodes, the gate electrodes (608a,..., 608f) formed on the insulating material and an electron emitting material (702) is deposited on active regions of the base electrodes, each active region (612) defined as a portion of each base electrode between a respective pair of gate electrodes. In one implementation, the FED produces a substantially uniform electric field in the active region (612) in order to produce a substantially straight electron emission little dispersion.</p> |
