ABSTRACT:
A color picture tube comprises electron guns disposed in the corners of a triangle, a slit-type shadow mask and a phosphor screen consisting of vertical phosphor stripes. In the electron-gun system and/or on the side thereof facing the deflection unit, or between the electron-gun system and the deflection unit, there is provided an additional magnetic deflector. This deflector serves to deflect the electron beams such that, within the range of action of the deflection unit, they extend in a horizontal common plane passing through the tube axis.
