Abstract

The invention provides a field emission electron device, which comprises an insulating base with a surface, multiple line electrode leads and multiple row electrode leads that are all arranged on the surface of the insulating base in parallel and at intervals, and multiple electron emission units arranged on the surface of the insulating base, wherein the multiple line electrode leads and the multiple row electrode leads mutually intersect to set and define multiple intersection points in an electric insulating manner, and each electron emission unit corresponds to one of the intersection points. Each electron emission unit further includes a second electrode electrically connected with the corresponding row electrode lead, a first electrode arranged at an interval with the second electrode and arranged in a manner of partially surrounding the second electrode at least, and multiple electron emission bodies arranged on the surface (far away from the insulating base) of at least one of the first electrode and the second electrode, wherein the first electrode is electrically connected with the corresponding line electrode lead.

Description

technical field [0001] The invention relates to a field emission electronic device, in particular to a planar field emission electronic device. Background technique [0002] Field emission electronic devices work at low temperature or room temperature, and have the advantages of low power consumption, fast response and low outgassing compared with thermal electron emission devices.
