P-37: Electrophoresis Deposition Method to Fabricate CNT-FED Cathode in Water Base Solution

A novel process for fabricating field emission display (FED) devices with pulse DC electrophoresis deposition (EPD) method in water base solution is proposed. Electrophoresis deposition method can be applied to both cathode and anode fabrication process. It is a fast and low cost process that is easily scaling up for large size panel. Mixing MWNT, which is synthesized by arc-discharge, and some “charger” with water, we can get CNT solution for EPD method. Cathode is coated with CNT film by the EPD method and using pulse electric field source. After some simple process of baking process and surface treatment, we can get the CNT-FED cathode with good emission performance.

19.2: Spray‐Coating Process for Preparing CNT‐FED Cathode

A novel process for fabricating field emission display (FED) devices with spray-coating method is proposed. Spray-coating method can be applied to cathode and even possible for anode fabrication process. It is a fast and low cost process that is easily scaling up for large size panel. Mixing MWNT, which is synthesized by arc-discharge, some conductive materials, and binding with solvent makes CNT mixture for spraying. Cathode is coated with CNT film by the spray process. After sintering process, it is evaluated by electron emission. This diode type CNT-FED with spray-coating process possessed good electron emission properties.
