Abstract: Methods of fabricating dot fluorescent screens for color television mask-type tubes are summarized, and the dot size control factors associated with the different methods are explored. Special emphasis is given to screening factors for focus mask-type tubes which have high-transmission masks. The tube and mask geometry is studied, and the effect of light-intensity gradients across the dot image as a function of light source size is considered. From these studies, and a knowledge of the physical characteristics of the binder and phosphor materials, an optical method of dot-size control is developed using photographic exposure time and light source size as the parameters. Lastly, annulus-shaped light exposure sources are considered and are shown to produce images having improved size control characteristics.
