Abstract
One anode 350 and multiple cathodes 50, 60, 70, and 80 create a large display field emission device. The use of one anode 350 facilitates an image which is seamless to the viewer. The use of multiple cathodes 50, 60, 70, and 80 allows a single image or multiple images to be displayed. The use of multiple cathodes also provides fast refresh rates and a high resolution image. Methods of fabricating and operating the large display field emission device are disclosed.
