Abstract: A cathode structure of triode type comprises, superposed, a cathode forming electrode (13) and supporting a layer of electron emitting material (14), an electrical insulating layer (11) and a grid electrode (15). An opening (12) cut in the grid electrode and in the electrical insulating layer exposes the layer of electron emitting material. The layer of electron emitting material is situated in the central part of the opening in the grid electrode. An Independent claim is also included for a flat field emission screen incorporating several of the above cathode structures.

Abstract: The flat screen display panel consists of two parallel plates defining between them an inter-electrode space. At least one of the parallel plates comprises small projecting tabs (20) in the active region. These tabs project a distance which is significantly less than the thickness of the space separating the two parallel plates. The tabs are grouped in either groups of three or four, and in such a group define a seating for a ball (23). The tabs may be aligned on the insulating lines which separate adjacent pixels of the screen, and may be in two pairs aligned along perpendicular axes. The ball serves as a spacer, defining the inter-electrode space and ensuring a uniform separation.
