Abstract

Device for the reproduction of color television images comprising a cathode ray tube and line deflector and electronic beam frame deviating means that produce a deflection field inside the cathode ray tube comprising an electronic gun an observation screen which irradiates light under electronic bombardment two color sorting grids that are mounted between the screen and the electronic barrel and whose active surfaces comprise exclusively parallel wires and a field electrode arranged on that side of the color sorting grids that are far from the cathode characterized in that the average potential of the color sorting grids is not greater than one tenth of the potential of the field electrode and that a grid of fine meshes provided between the color sorting grids and the field electrode has meshes whose width is equal to a maximum of one tenth of the sep aration between two successive wires of a color sorting grid and a potential that at most is equal to the average potential of the heat-selecting grids and that is not less than 10v than the lowest potential of a color-selecting grid with an electrode provided of focus whose potential is higher than the average potential of the aforementioned grids and lower than the potential of the field electrode between the deviator field and the color selection grids.
