Abstract: The invention concerns a black matrix in colour picture tubes, a positive photoresist composition, an agent for protecting a black matrix and a method of producing the latter. The object of the invention is to provide a black matrix which is produced by means of a positive photoresist composition, permits good structuring ability between exposed and unexposed regions, and reduces the method of producing the black matrix to a small number of technological steps. This object is achieved by obtaining a black matrix which consists of a light-absorbent matrix and can be produced from a positive photoresist composition consisting of a suspension which contains one or a plurality of compounds which indirectly or directly release gaseous compounds under the effect of light, a black pigment and suspension-stabilizing additives which enhance wetting and/or render the solution adhesive. The object is further achieved by obtaining an agent for protecting the light-absorbent matrix, which agent can be produced from a negative photoresist composition comprising a water-soluble organic polymer, a cross-linking actinic component, an alkylsilicate and water, said protecting agent having a pH of between 6 and 7.5.

Abstract: A process for making a pixelized phosphor structure involves the steps of forming an integral, non-layered mold by creating a plurality of openings in a substrate, and depositing a phosphor into the openings of the mold, thereby filling each of the openings of the mold with phosphor, and thereby forming a pixelized phosphor structure comprising an array of discrete phosphor elements. A second process for making a pixelized phosphor structure involves the steps of forming a first integral, non-layered mold by creating a plurality of first openings in a substrate, forming a series of one or more generations of replicas of the master mold, each of the one or more generations of replicas having a plurality of second openings, depositing a phosphor into the second openings of one of the one or more generations of replicas, thereby filling each of the second openings of the one of the one or more generations of replicas with phosphor, and thereby forming a pixelized phosphor structure comprising an array of discrete phosphor elements. A third process for making a pixelized phosphor structure involves the steps of providing a sheet of a first phosphor, creating a plurality of discrete holes in the first phosphor, each of the discrete holes extending through the first phosphor and having two openings, and depositing a second phosphor onto the first phosphor to form a pixelized phosphor structure, at least a portion of the second phosphor being deposited into the plurality of discrete holes in the first phosphor.

Abstract: Adherence of the phosphor screen to the face panel of a colour cathode ray tube is improved by placing a UV-reflective filter on the inside of the face panel prior to photolithographic forming of the screen, in order to reflect transmitted UV light back onto those areas from which the light emerged, thereby effectively increasing the exposure dosage of those areas.

Abstract: @ A colour-display picture tube display screen was made by providing a display screen substrate with a layer of a photosensitive composition which becomes sticky upon exposure to light. A black film matrix pattern and patterns of phosphor elements were formed on the photosensitive composition layer by imagewise exposing the layer to light in accordance with respective patterns of the black film matrix and of the respective phosphor elements, dusting the exposed layer with cobalt oxide particles and with particles of the respective phosphors, and blowing off the non-adhering particles. The photosensitive composition layer was then removed from the display screen substrate by condensing vapour of an organic solvent on the display screen structure so as to dissolve the material of the photosensitive composition layer, and continuing condensation of the solvent vapour until pure solvent falls off the substrate. During condensation of the solvent vapour the display screen is disposed so that the condensate falls off the substrate. The photosensitive composition is soluble in the solvent but the light-absorbing material and phosphors are insoluble in the solvent. The black film matrix and patterns of phosphor elements are fixed to the display screen substrate, for example, using an inorganic binder such as potassium metasilicate.

Abstract: A novel color selection electrode assembly is utilized in screening a pattern of phosphor areas upon the faceplate of a color cathode ray tube. The faceplate, which is formed of a material having a predetermined temperature coefficient of expansion, has registration affording means. The aforesaid assembly comprises an auxiliary mount formed of a material having a temperature coefficient of expansion greater than that of the faceplate and has a central opening of such span as to enable the mount to surround the periphery of the faceplate. Index bosses, cooperable with the faceplate registration affording means, are detachably secured to the mount. A planar metal foil having a predetermined pattern of apertures and formed of a material having a temperature coefficient of expansion not greater than that of the mount is secured to the mount. The index bosses cooperate with the registration affording means on the envelope to permit repeated precise registrations between the foil and the faceplate to facilitate screening of the phosphor pattern as well as to facilitate mating of the electrode assembly to the faceplate. Finally, the invention contemplates a method of utilizing the electrode assembly for screening a phosphor pattern as well as methods of making a color cathode ray tube having such an electrode assembly.

Abstract: In accordance with the invention, a photographic process for providing a phosphor pattern on a CCRT shadow mask comprises the steps of:
a) applying a uniform layer of a positive-working photoresist composition to the shadow mask surface, at least in the areas where phosphor is desired; b) applying a uniform layer of phosphor particles in contact with the photoresist layer; c) exposing the photoresist layer to actinic radiation through a positive photomask to solubilize the exposed portions of the photoresist layer; d) exposing the reverse side of the shadow mask to actinic radiation to solubilize portions of the photoresist layer in the aperture areas of the shadow mask; e) contacting the photoresist layer with a solvent to remove the solubilized portions of the layer; and f) baking the shadow mask to remove the remaining photoresist, to leave a uniform, adherent phosphor pattern layer on the mask. Such a process does not rely upon the use of a pattern stencil to define the phosphor pattern, and enables the application of a phosphor pattern without reducing the size of, or blocking the mask apertures.

Abstract: The invention relates to the provision of a paste on a substrate to manufacture color elements in accordance with a pattern, such as the provision of phosphor elements on display windows (for example of a CRT or a plasma display) or color-filter elements on substrates for display devices (for example LCDs). The dots can be provided on a substrate into a high or a low matrix, or on a substrate without a matrix. In particular, use can be made of special stencils which enable different layers to be successively printed on a substrate without a matrix, with previously printed layers hardly exerting an influence on the layers to be printed next.
