Abstract

A flat visual display device (100) comprises a cathode sector (20) including a backing electrode (12), a multi-electrode monolithic grid structures (50) and a face plate assembly (40). The multi-electrode monolithic grid structures (50) are applicable to array type thin planar vacuum tubes (100) utilizing planar virtual cathodes in close proximity to these grid structures. The grid structures incorporates selection, intensity control, modulation, focusing and in some cases all in single monolithic system.
