A GUN WITH A COLD CATHODE |
摘要 |
A gun with a cold cathode is disclosed in the present invention. A cold cathode made of a material for a cold cathode is held on a base, a mesh gate is right over the cold cathode, a focusing electrode in a circular hole-shape is right over the mesh gate, and the above-described electrodes are insulated with each other and held on the base. A mesh shielding electrode may be also provided right over the focusing electrode and is fixed on the base by a support for the shielding electrode. Depending on circumstances, the shielding electrode is required in a smaller device such as a pixel tube, but is not required in the applicattion of a cold lamp. The gun with a cold cathode according to the present invention is simple in structure, excellent in performance, and mainly used for a electron source, a electrical lamp with a cold cathode, and a pixel tube, it may be also used for other circumstances having the require similar to that.
