Abstract: A field emission display panel that utilizes nanotube emitters as electron sources and is equipped with two cathodes i.e. a primary cathode and an auxiliary cathode, and an anode is provided. The nanotube emitters can be suitably formed by nanometer-dimensioned hollow tubes of carbon, diamond or diamond-like carbon mixed in a polymeric-based binder. The nanotube emitters are formed in two parallelly-positioned, spaced-apart rows on top of an electrode layer such as a silver paste by a thick film printing technique. Since both the primary cathode and the anode are formed on the bottom glass plate, the operating voltage can be controlled by the thickness of the dielectric layer that is used in forming the nanotube emitter stacks. An auxiliary cathode formed of an electrically conductive material is coated on the interior surface of a top glass plate to further repel electrons in a downward direction toward the anode on the bottom glass plate. As a result, the distance between the top plate and the bottom plate can be chosen to allow the rapid evacuation of the panel cavity to form a high vacuum therein without affecting the operating voltage of the device. The present invention novel FED panel can be fabricated with a large panel area and at a low cost.

Abstract translation: 提供了利用纳米管发射体作为电子源并配备有两个阴极，即初级阴极和辅助阴极以及阳极的场致发射显示面板。 纳米管发射体可以由混合在基于聚合物的粘合剂中的碳，金刚石或类金刚石的纳米尺寸的中空管适当地形成。 纳米管发射体通过厚膜印刷技术在诸如银浆的电极层的顶部上以两个平行定位的间隔开的行形成。 由于初级阴极和阳极都形成在底部玻璃板上，所以可以通过用于形成纳米管发射极叠层的电介质层的厚度来控制工作电压。 由导电材料形成的辅助阴极涂覆在顶部玻璃板的内表面上，以在向下的方向上朝向底部玻璃板上的阳极进一步排斥电子。 结果，可以选择顶板和底板之间的距离，以允许快速抽出面板空腔以在其中形成高真空而不影响装置的工作电压。 本发明的新型FED面板可以制造成具有大的面板面积和低成本。
