Abstract
A field emission display includes a cathode plate and an anode plate. The anode plate is provided with an anode unit thereon. The cathode plate is provided on a cathode substrate with two electrodes that are located in a common plane and separated from each other to correspond to a common anode unit. Cathode electron-emitters are provided on the two electrodes respectively. A reverse voltage is applied to the two electrodes alternately, causing the alternation of the positive and negative voltages between the two electrodes. As a result, the two electrodes form a gate and an emitter alternately based on the applied positive or negative voltage. Therefore, the cathode electron-emitter provided on the coplanar electrodes will generate electron beams alternately.
