Abstract
A system for displaying a color broadcast television signal is provided. The system employs a cathode ray tube (CRT) which has only one electron gun and does not have a mask. The faceplate of the CRT has red, green, and blue phosphor stripes which form triads. A beam positioning gap, which may be patterned, is associated with each triad. By scanning the tube's electron beam along the beam positioning gap, vertical position information is obtained which is then used to accurately position the beam on the phosphor stripes as the stripes are scanned. Flyback of the electron beam can be avoided by scanning the phosphor stripes and the beam positioning gap in a serpentine pattern.
