Abstract
A color television picture tube device, of the type that includes: at least one electron gun; a screen of luminescent bands of different colors; a grid placed in front of the screen and in the vicinity thereof, said grid having openings whose direction coincides, at least approximately, with that of the bands, and said openings covering a portion of the grid surface at least thereof order that which is covered by the full portions; means for applying a high-value positive potential to the screen, said means including a coating covering the luminescent bands, said coating being such that during scanning of the screen by the beam from the barrel, an image of the grid more than for a grid potential lower than Vgo means to effectively apply to the grid a potential Vg lower than VE so that the grid-screen assembly constitutes a system of converging cylindrical lenses for said beam, said potential Vg being at least equal to VE/4, characterized in that the structure of said coating and the tension Vg are such that Vgo is lower than Vg and Vg is less than 3 Ve/4.
