John Kichul Lee has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 6417616
    Abstract: In one aspect, the invention encompasses a field emission display device. The device comprises a base plate and a face plate which is over and spaced from the base plate. The device further comprises emitters associated with the base plate and phosphor associated with the face plate. Additionally, the device comprises a reflector associated with the base plate and having an upper reflective surface. In another aspect, the invention encompasses a method of forming a field emission display device. A base plate is provided, and a pair of spaced emitter-containing regions are provided over the base plate. A reflector is formed over the base plate and between the spaced emitter-containing regions. A face plate is provided, and a pair of spaced phosphor-containing masses are formed in association with the face plate. The face plate and base plate are joined to one another with the face plate being aligned over the base plate and spaced from the base plate.

  • Patent number: 5712534
    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).
