ABSTRACT:
The invention relates to a method of manufacturing a color cathode ray tube, in which in one process step a color selection system and a glass display window having a display screen 2 are assembled. The color selection system and the display window are positioned relative to one another by optimizing a test pattern displayed on the display screen. The adjusted position of the parts relative to one another is then fixed by interconnecting weldable elements which are connected to the parts 1, 4, by means of laser welding through the glass.
