Patent abstract
A field emission display (FED) is provided. The FED has an emitter structure where the emitter, a conductor and a cathode electrode are so arranged to produce a certain electric field about the emitter. The electric field about the emitter causes the electron beam emitted from the emitter to have improved focus and have less dispersion. This causes the electron beam to hit the intended pixel without exciting phosphor layers in neighboring pixels, thus improving image quality.
