Abstract
A novel electron emitter utilizing the characteristics of ferroelectric ceramic materials has been developed. The electron emitter has a simple structure formed by using a thick film process, a small emission angle dispersion and its own memory function. The electron-emitting portion of the electron emitter has a unique microstructure. This micro-structure produces a novel two-step electron emission process by combining field emission characteristics with the ferroelectric characteristics of ceramic materials. To evaluate the electron emitter, a 4.3-inch prototype display panel was built that displayed a moving colored image using 128 gray scales per color.
