US Patent No: 7601043

Method of manufacturing microholes in a cathode substrate of a field emission display using anodic oxidation

---

Abstract

---

A field emission display (FED) with an integrated triode structure is provided. The FED can be manufactured without using a complex packaging process and have a significantly reduced well diameter and a significantly reduced cathode-to-anode distance. In the FED, front and rear panels form a single body using an anode insulating layer as an intermediate. A method for manufacturing the FED using anodic oxidation is also provided.
