Abstract

According to the electricity property that is the electric field strength will be increased at the edge of a structure, the edge of negative plate is exposed by opening a hole on the grid layer, and an edge structure is created on the emission source to increase the electric field of the emission source so as to reach the purpose of reducing the driving voltage.

Description

technical field [0001] The invention relates to a field emission display, in particular to a field emission display with a three-pole structure. Background technique [0002] The principle of field emission display is to apply the voltage between grid and anode in a vacuum environment to provide an electric field to attract the electrons at the tip of the material, and the field emission electrons leaving the cathode plate are attracted by the acceleration of the positive voltage on the anode and hit the coating. The phosphor powder on the anode plate emits light (Luminescence). [0003] Please refer to figure 1 As shown, the basic structure of the field emission display generally includes an anode plate 10 and a cathode plate 20 , and a vacuum state exists between the two plates 10 and 20 . The anode plate 10 forms an anode electrode layer 12 and a light-emitting layer 13 sequentially under the glass substrate 11, and the cathode plate 20 forms a cathode electrode layer 2...
