  • Publication number: 20110139365
    Abstract: Provided is a mask for an evaporation apparatus, which includes a first division mask and a second division mask. The first and second division masks are directly bonded to each other by welding, thereby forming welding portion between the first and the second division masks. A method and apparatus for manufacturing a mask for evaporation are also provided. The division masks according to the embodiment do not use subframes, and are directly bonded to one another by welding, so that a shadow effect does not occur. The apparatus for manufacturing a mask for evaporation includes a work stage, a clamp fixing a first division mask and a second division mask to the work stage, and a laser welding part welding the first division mask to the second division mask. The apparatus may further include a first roller leading the laser welding part and a second roller following the laser welding part.

  • Patent number: 7471036
    Abstract: A shadow mask for a cathode ray tube has an effective screen portion having a plurality of beam passage holes arranged in a predetermined pattern, and an inactive portion with no beam passage holes. The length of a beam passage hole at a column adjacent to a division between the effective screen portion and the inactive portion (hereinafter “the beam passage hole length”) in the long-sided direction is set to be smaller than the length of a beam passage hole placed at the short-sided center of the column. The beam passage hole length “a” at columns which are even-numbered from the long-sided center of the effective screen portion is set to satisfy the condition of 1>a/A?0.45, compared to the length A of the beam passage hole placed at the short-sided center of relevant columns. The beam passage hole length “b” at columns which are odd-numbered is set to satisfy the condition of 1>b/B?0.35, compared to the length B of the beam passage hole placed at the short-sided center of relevant columns.
