摘要：
Electrophoretic deposition provides an efficient process for manufacturing a field emission cathode (10). Particles (19) of an electron emitting material mixed with particles (18) of an insulating material are deposited by electrophoretic deposition on a conducting layer overlying an insulating layer to produce the cathode. By controlling the composition of the deposition bath and by mixing insulating particles (18) with emitting particles (19), an electrophoretic deposition process can be used to efficiently produce field emission cathodes that provide spatially and temporally stable field emission. The deposition bath for the field emission cathode includes an alcohol, a charging salt, water, and a dispersant. The field emission cathodes can be used as an electron source in a field emission source in a field emission display device.
摘要（中）：
电泳沉积提供了制造场致发射阴极（10）的有效方法。 与绝缘材料的颗粒（18）混合的电子发射材料的颗粒（19）通过电泳沉积沉积在覆盖绝缘层的导电层上以产生阴极。 通过控制沉积浴的组成并通过将绝缘颗粒（18）与发射颗粒（19）混合，可以使用电泳沉积工艺来有效地产生提供空间和时间上稳定的场发射的场致发射阴极。 用于场致发射阴极的沉积浴包括醇，充电盐，水和分散剂。 场发射阴极可以用作场发射显示装置中的场发射源中的电子源。
