    摘要: A process is provided for fabricating a multiplex screen structure for a color cathode ray tube whereof the window areas of a webbing structure are smaller than the apertures of a spatially related pattern member. The screen structure comprises a first apertured webbing of an opaque electrical conductive material formed by photo-processing on the inner surface of the tube viewing panel. A second apertured webbing of a substantially opaque material is electrophoretically superposed over the first webbing to provide a duo-webbing whereof the apertures are in alignment. The electrophoretic deposition of the second webbing produces a narrow mat-like encompassment within the perimeter of each aperture in the first webbing to effect a reduced-in-size second webbing aperture or window. An array of phosphor elements are formed to overlay the window areas, whereupon a reflective metallic backing is applied.

    摘要: Means and process are disclosed for disposing a patterned light attenuating coating of a differential density on a substantially transparent optical medium, used in the optical system for photoforming the windowed interstitial web portion of a color cathode ray tube composite screen structure. The apparatus comprises a hermetic chamber wherein there is included a vaporizing source, a rotatable first pattern mask, a movable second pattern mask, support means for positioning the optical medium, and optical means for monitoring the deposition of coating thereon. The apparatus enables the deposition of a nonsymmetrical coating formed to modify the photo-exposure illumination from the photoexposure light source.
