Abstract: A Braun tube for use in a TV receiver or the like, in which its screen does not need high resolution, but the brightness of the screen is important. The Braun tube has a panel with a flat outer surface, an electron gun arranged in an in-line manner and a phosphor screen whose phosphors are arranged in a delta pattern, and the horizontal pitch of a shadow mask can be varied in the direction of the Y-axis. The mechanical strength of the shadow mask is improved by making the curvature of the shadow mask larger than the curvature of the inner surface of the panel in the direction of the vertical axis of the screen.

Abstract: A tension mask for a color cathode-ray tube, a method for manufacturing the tension mask, and an exposure mask for use in the manufacture of the tension mask are provided. The tension mask is manufactured by depositing photosensitive layers over the top and bottom surfaces of a steel foil. An upper exposure mask with a pattern including a series of parallel upper light transmission portions arranged in lines is aligned over the top surface of the steel foil, and a lower exposure mask with a pattern is aligned over the bottom surface of the steel foil. Here, the pattern of the lower exposure mask includes a series of parallel lower light transmission portions arranged in lines, a plurality of first light shielding portions intersecting adjacent lower light transmission portions among the series of the parallel lower light transmission portions, and a plurality of second light shielding portions partially extending between the edges of the adjacent lower light transmission portions. Following this, the photosensitive layers uncovered with the lower and upper exposure masks are exposed using an exposure light source, and then the upper and lower exposure masks are removed from the steel foil and developing the photosensitive layers remaining on the steel foil. Lastly, the steel foil which has undergone the developing process is etched, so that the tension mask is completed.

Abstract: A shadow mask is formed by press molding and includes a substantially rectangular mask effective portion in the form of a gently sloped dome having electron beam passage apertures and a skirt portion extending from the peripheral edge of the mask effective portion. The skirt portion has a plurality of apertures arranged parallel to the peripheral edge of the mask effective portion and spaced from one another and belt portions formed between the apertures and an extending end edge of the skirt portion and extending along the extending end edge. Each of the apertures is formed so that its width increases from the peripheral edge of the mask effective portion toward the extending end edge side of the skirt portion.

Abstract: In color display tubes (1) with a dotted shadow mask (13) structure and an in-line electron gun (10), the geometry of the screen (6) and the deflection field produced by the deflection unit (11) cause triad rotation, which is a rotation of the three phosphor dots (red, green and blue) corresponding to one aperture of the shadow mask (13) with respect to the horizontal scan lines (35). This problem can be solved by giving the horizontal lines (35) a curved shape. However, in the prior art situation a parabolic shape is used, leading to severe moiré problems, because the vertical pitch asv (38) is influenced too strongly at the vertical screen edges. This problem can be overcome by using fourth order or even sixth order terms in the shape of the horizontal lines (35). A pure fourth order function reduces the vertical pitch asv 38 variation by 50% with respect to the parabolic prior-art situation, and a pure sixth order function even leads to a reduction by 67%.
