Conductive address structure for field emission displays
First Claim
1. An emitter structure for a baseplate of a field emission display, comprising:
- a substrate having a top surface;
an address line embedded in the substrate, the address line having an upper surface being at least substantially coplanar with the top surface of the substrate; and
an emitter assembly having an emitter superjacent to the top surface of the substrate apart from the address line and a contact having a first portion coupled to the emitter and a second portion coupled to the address line.

Abstract
An emitter structure for a field emission display includes: a substrate (100) having a top surface; an address line (142) embedded in the substrate (100) and having an upper surface substantially coplanar with the top surface of the substrate (100); and an emitter site (152) having an emitter (154) superjacent to the top surface of the substrate (100) apart from the address line (142) and having a contact (153) having a first portion coupled to the emitter (142) and a second portion coupled to the address line (142). The substrate (100) may further include a base layer (110), and a dielectric layer (120), and the contact (153) may further act as a resistor to limit the current to the emitter (154).
