Abstract: Apparatus for use as a lighthouse in the manufacture of a color cathode ray tube (CRT) includes a housing with a cover lens. Disposed within the housing is a light source assembly including a light source in the form of a cylindrical shaped mercury lamp and an optical aperture closely spaced to the mercury lamp. The mercury lamp directs light through the optical aperture as well as through the cover lens onto the inner surface of the CRT's glass faceplate in a photo-stenciling process for registering, or aligning, phosphor dots on the faceplate's inner surface with electron beam passing apertures in the CRT's color selection electrode, or shadow mask. The optical aperture is elongated, with its longitudinal axis aligned generally transverse to the longitudinal axis of the mercury lamp, and is curvilinear having from two (2) to eight (8) inflection points along its length.

Abstract: An electron beam addressed electro-optical (EO) light valve (EOLV) having a matrix of openings formed on and extending through an input conductive layer and further extends into an electrically insulating layer. A partially conductive coating is formed on the surface of each opening in the insulating layer, and has a substantially good electrical contact with the input conductive layer. An EO layer, formed of either a liquid crystal (LC) or a solid state EO crystal, is positioned on the optical output side of the insulating layer. Through the openings electrons from a scanning electron beam can reach and be directly deposited on the partially conductive coatings at a depth substantially close to the EO layer and substantially far away from the input conductive layer. The insulating material surrounding the openings in the insulating layer strictly prevents these deposited electrons from inter-opening motion.

The side of the plate on which the electron beam writes has an insulating layer of magnesium oxide.

Abstract: A flushing system is provided for a light valve of the Schlieren dark field type. A small amount of filtered fluid is injected into the space between the rotating disc and the output window of the light valve. This is done by injecting the fluid through the center disc bearing, thereby providing a uniform radial flow outwardly from the center and flushing out any particles in the space and preventing any particles in the surrounding fluid from moving into the raster area. By properly regulating the flow of the center flush fluid, the disc can be floated off the support during rotation. This reduces wear generated particles which contribute to substrate buildup and subsequent loss of light throughput. In addition, erratic disc motion caused by a stick and slip frictional effect is reduced.

Abstract: A neutralizing electrode is provided in a light valve of the Schlieren dark field type. The purpose of this neutralizing electrode is to neutralize the large electrostatic forces which develop between the transparent conductive electrode on the rotating disc and the face plate of the light valve causing erratic rotational motion of the disk. The neutralizing electrode is connected to a source of potential which is of the same polarity and substantially the same the potential as that of the rotating disk electrode.
