本文报导了一种用于平板显示的平面电子源。电子源除了包括灯丝外,还试用了三种不同结构的电极,以散射氧化阴极灯丝产生的电子流:一种是凸状电极,与灯丝相距一狭小空隙;第二种是圆柱形网状电极;第三种是椭圆形网状电极。在后两种电极结构中,灯丝放在电极中心。在最佳激励条件下三种电极都能产生均匀的平面电子流。椭圆形网状电极得到最均匀的电子流,其均匀性达到96%。还更进一步提出在矩阵电极外放一聚焦电极来聚焦通过矩阵电极时偏离的电子。目前各个领域都需要大面积、高分辨率 This paper reports a planar electron source for flat panel displays. In addition to including the filament, the electron source was also tested with three different configurations of electrodes to scatter the electron flow generated by the oxidized cathode filament: one is a convex electrode spaced a narrow gap from the filament; the second is a cylindrical mesh electrode ; The third is an oval mesh electrode. In the latter two electrode configurations, the filament is centered on the electrode. Under the best excitation conditions, all three electrodes can produce uniform planar electron flow. Elliptical mesh electrode to get the most uniform electron flow, the uniformity of 96%. It is still further proposed to place a focusing electrode outside the matrix electrode to focus the electrons that deviate when passing through the matrix electrode. At present, all areas require large area, high resolution
