High resolution CRT device comprising a cold cathode electron gun |
摘要 |
The CRT device comprises a cold cathode electron gun that includes cathodes, a peripheral focusing electrode, and an accelerating electrode. The cathode has a structure in which an emitter electrode and a gate electrode are joined together with an insulating layer interposed therebetween. The electric potential difference from the emitter electrode is 60V for the gate electrode, 0V for the peripheral focusing electrode, and 4.6 kV for the accelerating electrode.
