ABSTRACT:
A high resistance resistor for regulating current in a field emission display is integrated into circuitry of the field emission display. The resistor is in electrical communication with emitter sites for the field emission display and with other circuit components such as ground. The high resistance resistor can be formed as a layer of a high resistivity material, such as intrinsic polycrystalline silicon, polycrystalline silicon doped with a conductivity-degrading dopant, lightly doped polysilicon, titanium oxynitride, tantalum oxynitride or a glass type material deposited on a baseplate of the field emission display. Contacts are formed in the high resistivity material to establish electrical communication between the resistor and the emitter sites and between the resistor and the other circuit components. The contacts can be formed as low resistance contacts (e.g., ohmic contacts) or as high resistance contacts (e.g., Schottky contacts).
