Abstract
A flat display tube comprising an emission system (3) for emitting a planar electron beam (20), a modulation system (22) and a deflection system (5a, 5b, 28) for deflecting the planar electron beam towards the modulation system (22), which flat display tube also comprises a selection system (23) for selecting the planar electron beam transversely to this beam. The thickness of the electron beam (20) is increased by mutual repulsion of the electrons in the planar electron beam. The selection system in the flat display tube precludes that this adversely affects the resolution of the picture on the display screen.
