The flat anode display screen (5') comprises at least two sets of parallel bands of anode conductors (9) coated with luminophore material (7). These are separated from each other by insulating bands (8) which may be biased to different potentials as a function of the luminophore elements to be excited. The screen also includes focussing conductive bands (19,29) which are aligned and preferably centred with the insulating bands. The focussing bands have widths which are less than those of the insulating bands. The focussing bands may be biased to either a negative voltage, or zero voltage. The thickness of the insulating bands (8) is between 1 and 5 micrometres, whilst the width of the focussing bands is 20 - 60% of this size. |
