METHOD OF MANUFACTURING A CRT

摘要

The method of manufacturing a striped screen for a colored cathode-ray tube having a shadow mask with rows of elongate apertures. Adjacent apertures in each row are separated by a solid bridge. The photosensitized screen is exposed to light from a elongate light source parallel to the longitudinal directions of the apertures. By moving the light source uniformly during the exposure over a distance substantially equal to an integral number of times the length of the light source and the direction of the longitudinal axis, a line structure is exposed on the photosensitized screen, and the width of the lines is very constant.
