Abstract
A cathode ray tube device having an electronic cannon for producing a plurality of electron beams and a luminescent screen, on which side corresponding to the electronic cannon, at a short distance therefrom, is disposed a color selector electrode, in which the electron beams are made to converge in different electron beams, the electron gun comprising a separate cathode for each electron beam, in addition a first common grid provided with an opening for each beam, a second common grid serving as an accelerating electrode and which is provided with an opening for each beam, a third common grid having an opening for each beam and a fourth common grid of circular cross-section, characterized in that the distance between the successive centers of the openings of the third grid whose centers are substantially in one plane that passes through the geometric axis of the barrel, is less than 7 mm and l the dimension of the third grid in the openings in the direction of the axis of the barrel is not greater than 4 mm.
