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.

Abstract: A shadow mask for a Cathode Ray Tube (CRT) which achieves a high brightness and white uniformity by minimizing light emission of incorrect colors, includes: an effective screen portion with a plurality of beam passage holes arranged in a predetermined pattern and a non-holed portion surrounding the effective screen portion with no beam passage holes. The beam passage holes have a large-sized hole portion on a side facing a panel of the CRT and a small-sized hole portion that is smaller than the large-sized hole portion on a side facing an electron gun are selected such. A concave portion is formed on each of the beam passage holes arranged in a direction from a center of the effective screen portion to a direction of emission, and the concave portion is varied from the center of the effective screen portion diagonally such that a serif width D satisfies D=a−bx+cx2 (wherein a, b, and c are constants, and x is a spatial distance from the center of the effective screen portion to the center of the beam passage hole) and a, b, and c are selected such that {c/(b+c)} has an absolute value between 0.0092 and 0.0099.

Abstract: A tension mask assembly for a flat cathode ray tube includes a tension mask having a plurality of strips separated from one another by a predetermined gap, real bridges connecting adjacent strips to thus define slots through which electron beams pass, and first and second dummy bridges extending from adjacent strips toward each slot therebetween, the tension mask being installed such that its top surface faces a panel forming a screen and it is separated from the panel by a predetermined gap, a plurality of supporting members disposed at opposite sides of the tension mask to support the tension mask, and a plurality of rigid members secured to opposite ends of the supporting members to apply tension to the tension mask. A first etching boundary formed at an end of the first dummy bridge near to the center of the tension mask is lower with respect to the screen than a second etching boundary formed at an end of the second dummy bridge near to the periphery of the tension mask. The shape of a section of a slot having dummy bridges are formed such that an electron beam is prevented from passing through the slot, thereby solving the problem of visibility. Therefore, cathode ray tubes having a high definition can be manufactured.
