| titleOfInvention | Cold cathode structure for emitting electric field and electron gun using the cold cathode |
| abstract | The present invention relates to a field emission type cold cathode structure capable of emitting electrons by an electric field to prevent electron emission defects caused by impurities, and an electron gun using the cathode.n n n According to the present invention, a plurality of emitter chips are formed on a base electrode at predetermined intervals, a gate electrode is formed around each of the plurality of emitter chips, the base electrode and the gate electrode are electrically insulated through an insulating layer, and the base In a field emission type cold cathode structure having a structure in which a predetermined direct current voltage is applied between an electrode and a gate electrode, a low melting point metal layer is formed between the base electrode and each of the emitter chips, and above the gate electrode. By forming a focus electrode with an insulating layer interposed therebetween, and forming a control electrode with an insulating layer interposed therebetween, reducing power for heating the cathode, and quickly displaying data and images on the screen, It simplifies the structure of an electron lens that focuses an electron beam, and improves precision when assembling an electron gun.
