Field emission device and field emission display using the same having a concave-shaped cathode to enhance electron focusing |
摘要 |
A field emission device and a field emission display using the same. The field emission device includes a concave cathode electrode and an emitter formed at a center thereof. A gate electrode and a focusing gate electrode above the gate electrode serve to focus and refocus the electron beam emanating from the emitter to produce a better focused electron beam leading to improved color purity.
