Abstract
Fine particle size phosphors are adhered to the back of the aperture mask of a cathode ray tube by spraying a dispersion of such particles in a coating vehicle containing a temporary binder, and baking to remove the binder. The adhered phosphor is useful in providing information about the location of the scanning electron beams during tube operation.
