Single beam tracking tube |
abstract |
Single beam color CRT of the beam tracking type having a display screen comprising a plurality of parallel phosphor lines, the CRT being equipped with a Distributed Main Lens type electron gun. The distributed main lens has a plurality of oblong grids which each have a single, oblong, beam passing aperture. The longitudinal axes of the grids and of the apertures are transverse to the direction of the phosphor lines. Correction means are provided to compensate for the astigmatism introduced by the main lens. |
