Abstract: PROBLEM TO BE SOLVED: To provide an electrophotographic screening method manufacturing a uniform luminescent screen by providing a substantially uniform OPC layer during 8 seconds or less.
SOLUTION: The manufacturing method of a luminescent screen assembly includes a step overcoating an interior surface of a faceplate for forming a volatile organic conductive (OC) layer, and a step coating the OC layer for forming a volatile organic photoconductive (OPC) layer. The step of overcoating the OC layer is improved by grounding the OC layer, providing an OPC solution comprising a resin, an electron donor material, an electron acceptor material, and a mixture of two solvents having different boiling points, and spraying electrostatically-charged droplets of the OPC solution onto the OC layer, with at least one electrostatic spray gun, to provide an OPC layer, having uniform thickness, overlying the OC layer.

Abstract: PROBLEM TO BE SOLVED: To provide a color cathode-ray tube with a getter assembly, ensuring accurate positioning and orientation. SOLUTION: The color cathode-ray tube (10) has an evacuated envelope (11) including a funnel (15) sealed at one end to a face plate panel (12). A luminescent screen (22) is provided on an interior surface of the panel (12). A color selection electrode assembly (27) is disposed within the envelope (11) in proximity to the screen (22). An internal magnetic shield (30) having an exterior surface (32) is secured to the color selection electrode assembly (27) and is spaced from and extends along at least a portion of the funnel (15). The getter assembly (33) is disposed within the envelope (11) to deposit a film of a getter material onto the exterior surface (32) of the magnetic shield (30). The getter assembly (33) is improved by being detachably attached to the color selection electrode assembly (27) and prevented from rotating by an orientation plate (60) having a projection (70) with a flat contact surface bearing against the color selection electrode assembly (27).

Abstract: A spray module 40 for manufacturing a cathode-ray tube (CRT) 10 comprises an enclosure 42 having sidewalls 44, a base 46 attached to the sidewalls 44, for closing one end thereof, and a panel support 48 having an opening, 50 therethrough. The panel support 48 is attached to an opposite end of the sidewalls 44. The spray module 40 has at least one electrostatic spray gun 36 therein for spraying charged screen structure material through the opening 50 in the panel support 48 and onto an interior surface of a faceplate panel 12 of the CRT 10. The spray module 40 includes a primary shield assembly 55 disposed within the enclosure 42 and extending through the opening 50 in the panel support 48. A secondary shield assembly 56 also is disposed within the enclosure 42 The primary and secondary shield assemblies 55 and 56, respectively, direct the charged screen structure material toward the interior surface of the panel 12, thereby increasing the transfer efficiency of the spray gun 36. A collecting tray 54 also is utilized to catch the spent spray which falls to the bottom of the spray module 40. The tray 54 is inclined toward a drain 100 that directs the spent material out of the spray module 40.

Abstract: The invention relates to a method of manufacturing a luminescent screen structure 22 with a light-absorbing matrix 23, having a plurality of substantially equally sized openings therein, on an inner surface of a CRT faceplate panel 12. A color selection electrode 24 is spaced a distance, Q, from the inner surface. The method includes providing a first photoresist layer 50, whose solubility is altered when it is exposed to light, on the inner surface of the faceplate panel 12. The first photoresist layer 50 is exposed to light from two symmetrically located source positions +G and -G, relative to a central source position, 0. Then the more soluble regions 54 of the photoresist layer 50 are removed, overcoated with a light-absorbing material 58 and developed to remove the retained, less soluble regions 52 of the first photoresist layer with the light-absorbing material thereon. First guardbands 60 of light-absorbing material remain on the interior surface of the faceplate panel 12. The process is repeated twice more, using second and third photoresist layers 70 and 90 and two asymmetrically located light source positions +B, -B and +R, -R, respectively to produce second and third guardbands 80 and 100.

Abstract: Un TRC tiene un envolvente evacuado comprendiendo un embudo sellado en un extremo a un panel de placa frontal, con una pantalla luminiscente en una superficie interior del mismo. Un electrodo de seleccion de color, montado en una estructura, está dispuesto dentro del envolvente en proximidad a la pantalla. Un blindaje magnético interno está asegurado a la estructura del electrodo de seleccion de color, y está espaciado de, y se extiende a lo largo de, por lo menos, una porcion del embudo. El blindaje magnético tiene una pluralidad de aberturas a través del mismo. Un desgasificador evaporable está dispuesto dentro del envolvente adyacente a la superficie exterior del blindaje. El blindaje magnético está mejorado por tener lengüetas asociadas con las aberturas, para restringir el deposito de una película de material de desgasificador a la superficie exterior del blindaje.
